[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0059] The core of the present invention is to provide a method, device, equipment and medium for preventing accidental deletion of storage logical volumes, so as to solve the technical problem of accidental deletion of logical volumes.

[0060] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods. Figure 1 The flowchart of the storage logical volume anti-accidental deletion method provided by the embodiment of the present invention is as follows: Figure 1 As shown, the method includes the following steps:

[0061] S101: Receive an instruction to enable an anti-accidental deletion function.

[0062] S102: In response to the instruction to start the anti-accidental deletion function, extract the preset protection time.

[0063] It should be noted that the instructions for enabling the accidental deletion prevention function of the present invention can be specific to different types of logical volumes. These types of logical volumes can include standard volumes, compressed volumes, thin volumes, active-active volumes, local replicated volumes, remote replicated volumes, and the like. The instructions for enabling the accidental deletion prevention function can include the type of logical volume and a pre-set protection period. Different types of logical volumes have different accidental deletion prevention policies, which determine whether the accidental deletion prevention function is enabled for that type of logical volume and configure the corresponding protection period. This allows for effective and flexible protection of different types of volumes against accidental deletion.

[0064] The protection period can be pre-set by the administrator or user. It can be a fixed duration, such as 24 hours or 48 hours, or a fixed time period, such as from 8:00 AM to 8:00 PM on a particular day, or from 12:00 AM on the 1st to 12:00 PM on the 5th day. This allows for more refined configuration of the protection period based on actual conditions, adapting to various application scenarios and providing a wide range of applicability.

[0065] S103: Monitor the status of the logical volume.

[0066] In practice, the present invention can integrate a volume status monitoring module into a storage management system. The system uses the volume status monitoring module to monitor the status of logical volumes, including checking whether the logical volumes are active. Active logical volume status indicates that the logical volume has been activated and is accessible, allowing system administrators to operate the logical volume as needed and providing the basis for flexible management and dynamic adjustment of storage resources.

[0067] S104: When the logical volume is monitored to be in an active state, determine whether the logical volume is within the protection time.

[0068] If the logical volume is within the protection time, step S105 is executed; if the logical volume is not within the protection time, step S106 is executed.

[0069] S105: prohibit the operation of deleting the logical volume, and return corresponding prompt information.

[0070] In implementation, when an active logical volume is within the protection time, for example, the active logical volume is within a set time length or within a set time period, the deletion operation can be prohibited and the corresponding prompt information will be returned. This effectively prevents the logical volume from being accidentally deleted within the protection time, and reminds the system administrator that the logical volume is at risk of being deleted externally during the protection time, so that the administrator can promptly discover and handle possible erroneous operations, further improving the security of data storage.

[0071] S106: Allow the operation of deleting the logical volume.

[0072] In implementation, when the active logical volume is not within the protection time, for example, the active logical volume has exceeded a set time length or is not within a set time period, it may be allowed to be deleted.

[0073] In the above-mentioned storage logical volume anti-accidental deletion method provided by an embodiment of the present invention, after receiving the anti-accidental deletion function activation instruction, the anti-accidental deletion function is activated, the pre-set protection time is extracted, and by monitoring the active status of the logical volume, the logical volume is prohibited from being deleted within the protection time, and the corresponding prompt information is returned. In this way, an intelligent and automated anti-accidental deletion method is implemented, which can effectively prevent the logical volume from being accidentally deleted within the specified time, thereby avoiding data loss and system failure caused by accidental deletion operations, timely discovering and processing possible accidental deletion operations, and improving the security of logical volume management in the storage system.

[0074] Furthermore, in a specific implementation, in the above-mentioned storage logical volume anti-accidental deletion method provided in an embodiment of the present invention, step S103 monitors the status of the logical volume, which may specifically include: reading the input and output logs and access record information of the storage device; monitoring the status of the logical volume in real time or periodically based on the read input and output logs and access record information; and marking the logical volume as active when it is monitored that there are read and write operations or data changes on the logical volume.

[0075] In practice, the present invention can read the input / output (IO) logs and access records of storage devices in real time. Using these logs and access records, the status of logical volumes can be monitored in real time or periodically, including read and write operations, access frequency, and data changes. When read and write operations or data changes are detected on a logical volume, the logical volume can be marked as active.

[0076] Furthermore, in specific implementation, in the above-mentioned storage logical volume anti-accidental deletion method provided in an embodiment of the present invention, when the protection time is a set time period, a protection time label is added to the logical volume, and the start time and end time of the set time period are recorded; when the protection time is a set time length, when the logical volume enters an active state, the timing starts, and during the set time length, the operation of deleting the logical volume is prohibited.

[0077] In practice, the set time period has a start time and an end time. When the protection time is a set time period, it means that the protection time has a start time and an end time. The present invention can add a protection time tag to the logical volume according to the management settings to accurately determine whether the active logical volume is within the protection time. As long as the active logical volume is within the set time period, the operation of deleting the logical volume is prohibited. When the protection time is a set time length, the logical volume enters the active state and the timer of the set time length can be started. After the set time length, such as 24 hours or 48 hours, the operation of deleting the logical volume is prohibited.

[0078] Furthermore, in a specific implementation, in the above-mentioned storage logical volume accidental deletion prevention method provided by an embodiment of the present invention, if the logical volume is not within the protection time, the operation of allowing the logical volume to be deleted in step S106 may specifically include:

[0079] When the protection time is a set time period, if the logical volume is not within the protection time, the time at which the logical volume is after the end time of the set time period is determined; at this time, if the logical volume is still active, whether the active time of the logical volume per unit time exceeds the set time threshold is determined; if the active time of the logical volume per unit time exceeds the set time threshold, the end time of the set time period is automatically extended; if the active time of the logical volume per unit time does not exceed the set time threshold, the operation of deleting the logical volume is allowed; or, whether the input and output traffic of the logical volume per unit time exceeds the set traffic threshold is determined; if the input and output traffic of the logical volume per unit time exceeds the set traffic threshold, the end time of the set time period is automatically extended; if the input and output traffic of the logical volume per unit time does not exceed the set traffic threshold, the operation of deleting the logical volume is allowed.

[0080] Correspondingly, when the protection time is a set time length, upon receiving a deletion operation request, it is determined whether the logical volume has been in an active state for the set time length before the current moment; if there is an active state, the operation of deleting the logical volume is prohibited, and a corresponding prompt message is returned; if there is no active state, the operation of deleting the logical volume is allowed.

[0081] During implementation, when the protection time is a set time period, the threshold judgment method can be selected. When the threshold judgment is selected, it can be judged whether the volume activity level in unit time reaches the threshold, such as the volume activity time in unit time, the volume input and output traffic in unit time (that is, the access traffic of the host to the logical volume in the storage system), etc. If the set threshold is reached (if the default threshold in the program is not set), the end time can be automatically extended. This automatic adjustment of the protection time makes the anti-accidental deletion method more flexible and convenient.

[0082] When the protection time is a set length of time, for example, 12 hours, the protection time starts counting when the logical volume enters the active state. After 12 hours, if the logical volume is no longer in the protection time, the logical volume deletion operation can be allowed regardless of whether it is in the active state. However, when receiving a deletion operation request, the present invention can only consider whether there is an active state within 12 hours before executing the volume deletion operation. If so, the deletion operation is not allowed; otherwise, the deletion operation is allowed.

[0083] Furthermore, in a specific implementation, in the above-mentioned storage logical volume anti-accidental deletion method provided in an embodiment of the present invention, step S104 determines whether the logical volume is within the protection time, which may specifically include: traversing the active state of the logical volume, reading and counting the latest access time of the logical volume; determining whether the latest access time exceeds the protection time; if so, determining that the logical volume is not within the protection time; if not, determining that the logical volume is within the protection time.

[0084] In practice, after the accidental deletion prevention function is enabled, the storage system can automatically read and count the latest access time of the logical volume from the background and save the data. Based on the comparison result of the latest access time and the protection time, it is determined whether the logical volume is in the protection time, which can further ensure the accuracy of accidental deletion. The latest access time of the logical volume counted by the present invention can include the latest access time of the specified volume, the latest access time of the host-mapped volume, the latest access time of the mapped volume within the input and output group, the latest access time of the mapped volume within the volume group, and the latest access time of the mapped volume within the host group.

[0085] Furthermore, in specific implementation, in the above-mentioned storage logical volume anti-accidental deletion method provided in an embodiment of the present invention, while prohibiting the operation of deleting the logical volume, it can also include: prohibiting the logical volume from releasing the host mapping relationship, prohibiting the deletion of active hosts, prohibiting active hosts from deleting mapped ports, and prohibiting active hosts from deleting the input and output groups to which they belong.

[0086] In practice, in addition to providing deletion protection for protected logical volumes, the present invention can also provide deletion protection for the storage-related modules involved, including preventing active volumes from releasing host mapping relationships, preventing active hosts from accidentally deleting volumes, preventing active hosts from deleting mapped ports, preventing active hosts from deleting their assigned input and output groups, and preventing related host-combined volume groups from accidentally being deleted.

[0087] Furthermore, in specific implementation, in the above-mentioned storage logical volume anti-accidental deletion method provided in an embodiment of the present invention, receiving an anti-accidental deletion function activation instruction may specifically include: receiving an anti-accidental deletion function activation instruction from a visual management interface or a command line interface (CLI).

[0088] Similarly, the method may further include the steps of: receiving an instruction to turn off the anti-accidental deletion function from a visual management interface or a command line interface; and stopping monitoring the status of the logical volume.

[0089] During implementation, the system provides a visual management interface or command line interface to facilitate administrators in setting and viewing information such as the active status and protection time of logical volumes. Administrators can use this interface or command line interface to easily set protection time for logical volumes, view the active status of logical volumes, and enable or disable the volume's accidental deletion protection feature. This allows for personalized customization, with the ability to set global or customized configurations. Code logic is implemented through environment variables, improving management efficiency and reducing operational difficulty and complexity. The command line interface allows users to enter commands to enable or disable the accidental deletion protection feature via the keyboard, and the computer executes the commands upon receiving them.

[0090] In the above embodiments, a method for preventing accidental deletion of a storage logical volume is described in detail. The present invention also provides corresponding embodiments of a storage logical volume accidental deletion prevention apparatus and a storage logical volume accidental deletion prevention device. It should be noted that the present invention describes embodiments of the apparatus from two perspectives: one based on functional modules and the other based on hardware.

[0096] The deletion operation restriction module 14 is used to prohibit the operation of deleting the logical volume and return a corresponding prompt message if the logical volume is within the protection time; and to allow the operation of deleting the logical volume if the logical volume is not within the protection time.

[0097] In the above-mentioned storage logical volume anti-accidental deletion device provided in an embodiment of the present invention, the above-mentioned five modules can interact with each other, and after receiving the anti-accidental deletion function activation instruction, the anti-accidental deletion function can be activated, the pre-set protection time can be extracted, and the deletion of the logical volume can be prohibited within the protection time by monitoring the active status of the logical volume, and corresponding prompt information can be returned. In this way, an intelligent and automated anti-accidental deletion method is implemented, which can effectively prevent the logical volume from being accidentally deleted within the specified time, thereby avoiding data loss and system failure caused by accidental deletion operations, timely discovering and processing possible accidental deletion operations, and improving the security of logical volume management in the storage system.

[0098] Since the embodiments of the apparatus part correspond to the embodiments of the method part, the embodiments of the apparatus part refer to the description of the embodiments of the method part and are not described here in detail. The invention has the same beneficial effects as the above-mentioned storage logical volume accidental deletion prevention method.

[0099] Furthermore, in a specific implementation, in the storage logical volume anti-accidental deletion device provided in an embodiment of the present invention, the instruction receiving module 10 can be specifically used to receive an anti-accidental deletion function activation instruction from a visual management interface or a command line interface.

[0100] Correspondingly, the instruction receiving module 10 can also be used to receive an instruction to disable the anti-accidental deletion function from the visual management interface or command line interface. After the instruction receiving module 10 receives the instruction to disable the anti-accidental deletion function, the volume status monitoring module 12 can stop monitoring the status of the logical volume.

[0101] Furthermore, in a specific implementation, in the above-mentioned storage logical volume anti-erroneous deletion device provided in an embodiment of the present invention, the volume status monitoring module 12 can be specifically used to read the input and output logs and access record information of the storage device; based on the read input and output logs and access record information, the status of the logical volume is monitored in real time or periodically; when it is monitored that there are read and write operations or data changes on the logical volume, the logical volume is marked as active.

[0102] Furthermore, in specific implementation, in the above-mentioned storage logical volume anti-accidental deletion device provided in the embodiment of the present invention, the protection time can be a set time period or a set time length; when the protection time is a set time period, a protection time label is added to the logical volume, and the start time and end time of the set time period are recorded; when the protection time is a set time length, the timing starts when the logical volume enters the active state, and the operation of deleting the logical volume is prohibited during the set time length.

[0103] Furthermore, in a specific implementation, in the above-mentioned storage logical volume anti-accidental deletion device provided in an embodiment of the present invention, the time judgment module 13 can be specifically used to traverse the active state of the logical volume, read and count the latest access time of the logical volume; judge whether the latest access time exceeds the protection time; if so, judge that the logical volume is not within the protection time; if not, judge that the logical volume is within the protection time.

[0104] Furthermore, in a specific implementation, in the storage logical volume accidental deletion prevention device provided in an embodiment of the present invention, the deletion operation restriction module 14 may specifically include:

[0105] The first restriction unit is used to, when the protection time is a set time period, if the logical volume is not within the protection time, determine the time when the logical volume is after the end time of the set time period; at this time, if the logical volume is still in an active state, determine whether the active time of the logical volume per unit time exceeds the set time threshold; if the active time of the logical volume per unit time exceeds the set time threshold, automatically extend the end time of the set time period; if the active time of the logical volume per unit time does not exceed the set time threshold, allow the operation of deleting the logical volume; or, determine whether the input and output traffic of the logical volume per unit time exceeds the set traffic threshold; if the input and output traffic of the logical volume per unit time exceeds the set traffic threshold, automatically extend the end time of the set time period; if the input and output traffic of the logical volume per unit time does not exceed the set traffic threshold, allow the operation of deleting the logical volume.

[0106] The second restriction unit is used to determine whether the logical volume has been in an active state for the set time length before the current moment when a deletion operation request is received when the protection time is the set time length; if the active state exists, the operation of deleting the logical volume is prohibited and a corresponding prompt message is returned; if the active state does not exist, the operation of deleting the logical volume is allowed.

[0107] Furthermore, in a specific implementation, in the storage logical volume accidental deletion prevention device provided in the embodiment of the present invention, the deletion operation restriction module 14 may further include:

[0108] The third restriction unit is used to prohibit the logical volume from releasing the host mapping relationship, prohibit deleting the active host, prohibit the active host from deleting the mapped port, and prohibit the active host from deleting the input and output group to which it belongs.
