Techniques are taught for encrypting one or more target partitions effectively “in-place”. This effectively in-place encryption is extremely desirable when a root / OS partition (such as / , / usr, / bin, etc.) needs to be encrypted without having to manually back up its contents to another location where they may be exposed in plaintext form, encrypting a new partition, and restoring the contents back to it. The techniques of the present disclosure are also applicable for encrypting effectively in-place user data partitions. To accomplish its objectives, the technology provides an install sequence / process and a modified boot sequence to automatically encrypt partitions effectively in-place. In various embodiments, the selection of copy partitions where copy data is temporarily stored in encrypted form, is performed manually or automatically. In other embodiments, a logical volume manager (LVM) is employed that greatly facilitates provisioning of free space in the system where copy data will be temporarily and securely held / stored.

This disclosure presents a method for local high-performance storage processing based on logical volume management in a cluster. One specific implementation of this method includes: aggregating the disk space corresponding to each specified cluster node in the node cluster to obtain a resource storage pool; deploying a corresponding container interface service plugin for each cluster node in the node cluster; performing resource validity verification on the resource object to be constructed; in response to the successful resource validity verification of the resource object creation task, controlling the cluster scheduler to select a cluster node adapted to the resource object to be constructed as the target cluster node; controlling the container interface service plugin in the target cluster node to dynamically create the resource object and its corresponding logical volume in the resource storage pool of the target cluster node according to the resource object creation task, and binding the logical volume to the resource object. This implementation ensures efficient recycling of storage space.

Embodiments of the present disclosure disclose a logical volume manager-based disk allocation method, device, equipment and medium. A specific implementation of the method comprises: in response to receiving a disk allocation request sent by a client corresponding to a target user, performing loading processing on metadata of a volume group corresponding to the disk allocation request to obtain loaded metadata; performing analysis processing on the loaded metadata to generate a physical volume region object linked list and a physical volume label set; performing storage format conversion processing on the physical volume region object linked list to generate a physical volume region object array; performing mirror grouping processing on the physical volume region object array using the physical volume label set to generate a physical volume mirror sub-group array; and performing strip allocation processing on the physical volume mirror sub-group array to complete a disk allocation operation task. The implementation can improve the utilization of disk resources and the performance of a storage system while ensuring data redundancy and reliability.

The invention discloses a volume group configuration management method and device for logical volume management, equipment and a medium, and relates to the technical field of computers. The method comprises the following steps: constructing a volume group management drive program, and loading the program in a firmware initialization stage before an operating system is started; accessing an available storage device of the server through the volume group management drive program, and analyzing logical volume management metadata on the available storage device to extract a current volume group name; performing mode matching on the current volume group name and a preset conflict name list, and judging whether volume group naming conflict exists or not; if yes, modifying a volume group name field in the logical volume management metadata to update a conflicting volume group name into a new name, and writing back the modified logical volume management metadata to the available storage device. According to the technical scheme, the volume group naming conflict of logical volume management can be detected and avoided before the system is installed, so that the storage operation and maintenance efficiency is improved, and the manual intervention cost is reduced.

The embodiment of the invention discloses a logical volume manager-based disk allocation method and device, equipment and a medium. A specific embodiment of the method comprises the following steps: in response to a received disk allocation request sent by a client corresponding to a target user, loading metadata of a volume group corresponding to the disk allocation request to obtain loaded metadata; performing analysis processing on the loaded metadata to generate a physical volume region object linked list and a physical volume label set; performing storage format conversion processing on the physical volume area object linked list to generate a physical volume area object array; performing mirror image grouping processing on the physical volume region object array by utilizing the physical volume label set to generate a physical volume mirror image sub-grouping array; and performing stripe allocation processing on the physical volume mirror image sub-grouping array to complete a disk allocation operation task. According to the embodiment, on the premise of ensuring data redundancy and reliability, the utilization rate of disk resources and the performance of a storage system can be improved.
