RAIDZ Calculator

This RAIDZ calculator computes zpool characteristics given the number of disk groups, the number of disks in the group, the disk capacity, and the array type both for groups and for combining. Supported RAIDZ levels are mirror, stripe, RAIDZ1, RAIDZ2, RAIDZ3.

RAIDZ Recovery

Remember that RAIDz is not perfect. You can still lose the zpool due to the hardware failure or operator error. If this happens, the first recommended action is to shut down the system and disconnect the drives.

Next, search the web for a possible solution. We stick to the read-only ZFS recovery approach with our ReclaiMe Pro software.

The software is capable of both reading slightly damaged ZFS metadata and reconstructing broken ZFS pool in cases where metadata records are lost.
