RAID 10 Recovery

#1

Post by andy@omygoodness.com »

I am in the middle of a Forced Upgrade to NAS4Free after I had my USB die. I had 4 disks running a RAID 10. I had an initial challenge in that I didn't realize that freeNAS had forked and spent 3 days working with their latest. During which I removed 1 of the drives from 1 of my mirrors. So I used the ISO to create a new USB, started up the USB and Disks/Management/Import Software Raid Disks. This brought in the Mirrors correctly for the RAID 1 portion, but it didn't bring in the second part and add the RAID 0 across the top. When I go to Disks/Software Raid/Raid 0/1/5 and click on +, no disks show up. When I set up the disks, I needed to format Mirror 1 & Mirror 2 before I could build the RAID 0. I am afraid to do the formatting for fear that I'll loose my data (if it is not already lost!).

The Raid 10 has been imported:
nas4free:/dev/gvinum# ls -l
total 0
crw-r----- 1 root operator 0, 136 Nov 25 02:21 HomeDocs
crw-r----- 1 root operator 0, 137 Nov 25 02:21 HomeDocsp1

Any suggestions? Do I still have a shot at recovering my data? I have a partial backup, but not a current one. So I would like to try to restore if possible.

OK. Over 1 week, 29 readers and no answers. I'll take that as a reminder that RAID <> BACKUP, rebuild from scratch and move on. Meaningful lessons seem to always need to hurt.

If you don't get answers try in another ZFS-related forum, it works the same way in different operating systems with also the same command line options.

sorry no experience on RAID10 only on ZFS.

In general do a backup of your valuable data prior to a great change is clever.

PD: This time valorate to use ZFS RaidZ2 not Raid10, in general you have less problems and are well supported in this forum.
