摘要： A data management method for logical volume manager (LVM), called LVM includes a first type of physical volume and a second type of physical volume. Access speed of the first type of physical volume is higher than that of the second type of physical volume. Each physical volume has a plurality of physical extents, and a data storage method includes the following steps. Obtaining access frequencies of all the physical extents in statistics; performing a data migration operation, migrating and saving data in the physical extents satisfying an access frequency threshold value in the second type of physical volume to the physical extents without any data in the first type of physical volume; and rewriting a corresponding physical extent number for the migrated data.

摘要： A remote replication synchronizing/accessing system and a method thereof applied between a local system and a remote mirroring system of the local system. After the remote mirroring system is created, an initialization synchronous operation of the remote mirroring system is sequentially performed according to a sequence of data blocks in storage of the local system. A small-granulated exclusive lock function is established between the initialization synchronous operation and a data-accessing request operation of the local system. During the initialization synchronous process of the remote mirroring system, it is determined whether a data block position corresponding to the current initialization synchronous operation is the same as that corresponding to the data-accessing request operation or not. Finally, according to a position determination result and the small-granulated exclusive lock function, a data-accessing request is directed processed or processed after finishing the initialization synchronous operation.

摘要： A data manipulation method of a logical volume manager is applicable to data management of dependent snapshot volumes (SVs) of a logical volume manager. The data management method includes the following steps generating a plurality of SVs, defining the SV generated at first as a first SV, defining the SV generated at last as a last SV, and defining the rest SVs as middle SVs; selecting a middle SV; combining content stored in the selected middle SV into a neighboring SV; according to the combined SV, combining meta-data of the selected middle SV into meta-data of the middle SV; deleting the selected middle SV. The logical volume manager does not need copy the data again, thereby saving access time in data management.

摘要： A method for processing a bad block in a redundant array of independent disks (RAID) is presented, which is characterized by a software RAID constructed by a scale computer interface disk, and adapted to backup data in a bad block in the software RAID. The method includes invoking an access error program to intercept an access instruction for a data block in the software RAID when the data block is a bad block; searching a disk number and a logical block address of the data block in the software RAID according to the access instruction; selecting the scale computer interface disk; and mapping data stored in the data block, the disk number, and the logical block address to a reserved local memory of the scale computer interface disk. Through the above steps, the data in the bad block can be mapped to a normal block, thus maintaining the data integrity.
