Hi everyone using the latest unraid version I had a zfs pool with 3 drives in raidz.

I tried to replace one of the drives but unfortunately somehow I managed to get the pool all messed up.

Even though I added the old drive back when I start the array I get a message saying "Unmountable: unsupported or no file system"

When I use the zpool import this is what I get:

   pool: cachessd
     id: 16821189125514654564
  state: UNAVAIL
status: One or more devices contains corrupted data.
 action: The pool cannot be imported due to damaged devices or data.
   see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-5E
 config:

        cachessd                    UNAVAIL  insufficient replicas
          raidz1-0                  UNAVAIL  insufficient replicas
            sde1                    ONLINE
            replacing-1             UNAVAIL  insufficient replicas
              14112098753288857692  UNAVAIL
              9022637102148647340   UNAVAIL
            sdd1                    UNAVAIL

As I said I have back in all the original drives. Is there a way to get them back online and not loose any data?

Many thanks,
zen

 

PS: If I destroy and recreate the pool with the original drives, will I lose all the data?

What happened to this device, is it still connected?

Yes it is still connected. However, when I connected it back it gave me an error:
"Unraid Cachessd 3 errorAlert [HADES] - Cachessd 3 in error state (disk bad)ST1000LM024_HN-M101MBB"

 

Is there a way to cancel the replacing-1? I change this disk back to the original so there is no need to do any replacement.

Somehow I would like to change:

replacing-1 UNAVAIL insufficient replicas

  14112098753288857692 UNAVAIL

   9022637102148647340 UNAVAIL

Not that I know of, best bet would be to get the other missing disk to show up, try replacing cables since SMART looks fine.

 

After replacing cables power back on, don't start the array and post the output of 

zpool import

I still get the same

I don't seem to be able to get the missing drive to show up.

In that case don't know what else you can do other than recreating the pool and restoring from a backup, if available.

Just one more thing, post the output of

blkid

 

Thanks for trying to help @JorgeB.

In the end I just erased and recreated the pool from scratch.

By the way, now I have 1 disk under unassigned devices with label pool greyed out. How can I format this one and just use it as an unassigned device?

Wipe it first with UD (requires destructive mode enabled) or with wipefs for example.

Thanks again, I used fdisk to remove the zfs_member signature.
