Detailed Description

Pool version is the subset of devices from the filesystem configuration: racks, controllers, disks, etc. If the whole cluster hardware configuration is represented as a tree, the pool version would be its sub-tree.

Motr objects and indexes are assigned some pool version when they are created.

Pool version is associated with a pool machine and contains a device to ioservice map.
