Hello,
Yesterday I was replacing a failing drive (turned the failing drive off, added new hdd, clicked replace, waited for resilvering). Afterwards my VMs and Jails stopped working, so I rebooted. Come to find out FreeNAS cannot see my ZFS pool.
I ran
System details and other info:
I do have a backup on old external drives, unfortunately they are roughly a year old. Really hoping we can save the data somehow, best case scenario reattach the pool and I get spanked and immediately create a backup. A tiny bit terrified right now.
Edit: Oh ffs. Apparently I unplugged a HDD somehow, so FreeNAS didn't attach the pool. Plugged the HDD back in, and all my files and stuff are back. Now to back everything up.
Yesterday I was replacing a failing drive (turned the failing drive off, added new hdd, clicked replace, waited for resilvering). Afterwards my VMs and Jails stopped working, so I rebooted. Come to find out FreeNAS cannot see my ZFS pool.
I ran
zpool import -fF ZFS
, this came back with the error:Code:
cannot import 'ZFS': I/O error Destroy and re-create the pool from a backup source.
System details and other info:
- Intel i3-4330 CPU at 3.50GHz (4 cores)
- 32 GB RAM
- FreeNAS-11.2-U7
- 2x Raidz2, for a total of 8 2tb hdds
- The hard drive failure was in one Raid, the other showed up as fine
- I messed up. There was a hard drive failure in August (?), but I didn't have the time to replace the hdd so I just unplugged it and let the raid run degraded. A second hard drive failure came up about two weeks ago, so yesterday I decided to replace it.
- Turn off newly failed hdd, unplug it, add in new hdd, click "replace" from the webgui
- Also plugged in old failed hdd. Then I stupidly turned it on, thinking it should "turn on" within the webgui so I can confirm the right hdd and then turn it off and replace it.
- Seemed to be working fine (freenas gui was reporting resilvering and replacing progress), but plex and VMs weren't working.
- Waited 24 hours, rebooted server. And here we are
- Last scrub of the pool was Dec 31, 2019
freenas-debug -A
command, not sure what would be useful but the output is attached below. I can't find a history of messages, just a current diagnoses, but I'm not sure if I'm looking at the right places.I do have a backup on old external drives, unfortunately they are roughly a year old.
