This invention belongs to the field of integral bladed disk size detection technology, and provides a three-coordinate measuring machine (TCM) method for detecting the dimensions of a double-layer integral bladed disk. The method includes the following steps: Step 1, designing the TCM probe structure based on the disk structure; Step 2, configuring the calibration ball orientation for the probe structure; Step 3, calibrating all probes and placing them in the probe replacement rack; Step 4, establishing the disk coordinate system; Step 5, automatically running the program and calling the corresponding probes to scan the disk profile; Step 6, using the scanned data for dimensional evaluation. This invention efficiently completes the detection of the double-layer integral bladed disk profile, avoids missing disk dimensions, achieves quality control, improves measurement efficiency and accuracy, and increases detection efficiency by 50%.

Systems and methods for supporting dynamic disk growth within a storage appliance are provided. According to one embodiment, a portion of a logical size of each of multiple disks (e.g., hyperscale disks or Logical Unit Numbers (LUNs)) are provisioned for use by a storage system as backing for respective file system disks. To accommodate growth, block numbers for the file system disks are pre-allocated within a sparse space of a contiguous sequence of block numbers corresponding to a number of blocks represented by the logical size. Metadata is maintained for the file system disks regarding a range of the pre-allocated block numbers that are available for use. Responsive to a triggering condition, the provisioned portion of a disk is increased and subsequently, responsive to detecting a change in a size of the disk by the storage system, a size of the corresponding file system disk is updated within the metadata.

The invention discloses an improved SLR-DP coding multi-disk repair data storage method, which comprises the following steps of: determining the number of disks for storage according to the size of original data and the size of the disks; dividing the original data into disks and segmenting the original data according to a specified size to form a plurality of data blocks which are arranged in sequence; performing staggered placement on the local redundant disk groups; and encoding the horizontal redundant blocks and the diagonal redundant blocks on the global redundant disk group, and respectively placing the horizontal redundant blocks and the diagonal redundant blocks in two disks in the global redundant disk group. According to the method, the calculation amount of redundant data recovery is reduced through a local recovery mechanism, so that when the fault occurs, the lost data block can be quickly identified and recovered, the data recovery time is greatly shortened, the response speed of the system is improved, and particularly, the recovery speed is higher than that of a traditional scheme under the condition of single-disk and double-disk faults.

The invention provides a method and a device for adjusting a storage space of a container data volume. Relates to the field of container data volume storage capacity expansion, and aims at a scene that a kata security container uses an external iscsi disk as a data volume, when a container storage plug-in controller module (controller) receives a capacity expansion request, the method comprises the following steps: firstly, carrying out capacity expansion on an iscsi LUN on an external storage system, then executing an operation of scanning the disk on a host running by the container to obtain a new size of the iscsi disk, and finally, carrying out data volume expansion on the new size of the iscsi disk. The method comprises the following steps: when a file system is mounted on a kata virtual machine, a container storage plug-in node module notifies a kata container to update the size of a data volume, finally, after a kata-agent running in the kata virtual machine receives a capacity expansion request, the space size of a virtual disk is refreshed, the file system on the virtual disk is expanded in a mounting state, and finally the capacity expansion processing is completed.
