Raidz and ZFS file system support
We are proud to present RAID Z and ZFS file system support to VMFS Recovery.
Errors in ZFS are not common as all data stored on this file system is constantly checksumed, checked for integrity and self healed. However sometimes it needs expert treatment too. Developers said they had a real pleasure to work with this complex and well thought-out file system and were also impressed with RAID Z realization. Normally RAID disk is one or two levels above the file system and is not to be affected in any way. Raidz represents a completely different approach mixing the file system, disks and files together and allowing similar features as RAID 5, but with a gain of improved performance and ability to self-heal a ZFS disk has.
Current realization of Raidz recovery doesn't integrated with Raid Wizard, like other RAID levels does. You need to open one of Raidz disks in order to start reconstruction process.
