A method, apparatus and program storage device for dynamically resizing mirrored virtual disks in a RAID storage system is disclosed. Mirrored virtual disks are expanded by creating the amount of storage necessary by providing RAIDs on each subsystem that is associated with each of the components of the mirror set, attaching the RAIDs to the specific Virtual Disks for each of the mirror devices, and specifying the Virtual Disk size and mapping this directly to all components via the source Vdisk of the mirror set. To decrease the size of mirrored virtual disks the process is reversed, with the inclusion of the optional requirement that some raids will need to be truncated to provide exact shrink values without sacrificing storage space.

The invention discloses a rapid horizontal extending method for databases, which belongs to the field of data migration and storage. The method comprises the following steps: a monitoring and control system carries out monitoring on the disk storage space of the existing database, and when the disk size reaches a preset storage capacity threshold, the monitoring and control system triggers a hardware storage increasing action so as to make a hardware environment preparation for data migration; and a routing protocol carries out a modular computation on the instance number N of the current database according to a major key ID to be inserted currently, and routes the line number of data to be inserted into a specified database, and when the number of inserted lines exceeds a preset storage number threshold, the routing protocol triggers a database segmentation action so as to migrate specified data into a new database, thereby completing the rapid horizontal extending of the database. The method disclosed by the invention can be applied to disk databases or memory databases, and the method is easy to use and simple, and avoids the problem that hotspots are distributed nonuniformly caused by traditional horizontal extending of databases; in addition, as the scale of migration of data segmented each time is small, the extending speed is improved. In conclusion, the overall architecture meets the requirements on high availability, high reliability, high speed, high efficiency and the like.

A computer-implemented method includes identifying a request to translate an existing storage pool having a smaller first chunk size to an expected storage pool having a larger second chunk size. Reels in an existing storage pool are reordered such that boundaries between physical tile disks of a volume and tile disks of an intended storage pool are aligned. Each of the blocks in the existing storage pool is transitioned from the first block disk size to a second block disk size. Thereafter, for each of the volumes: a temporary pause/lock is performed on the VST entry corresponding to the given volume, and an existing structure associated with the VST entry corresponding to the first block disk size is removed. In addition, the VST entry is populated with a new structure corresponding to the second block disk size.
