October 26, 2025Oct 26 Hello everyone, I unfortunately misread something while changing an array and ejected/deleted my ZFS z2 pool with the “new config” tool. I then rewrote the config file from a USB backup onto the Unraid USB stick, but unfortunately it does not recognize the Raidz2 and always writes “Unmountable: wrong or no file system.” Would anyone be so kind as to help me? Thanks 🙂in the pool import I see that de device sdj is two times in there and in the unread main gui is it not!root@Diskstation:~# zpool import pool: zfs.spinners id: 263348690834153820 state: FAULTED 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: zfs.spinners FAULTED corrupted data raidz2-0 DEGRADED sdj1 ONLINE sdg1 ONLINE sdh1 ONLINE sdi1 ONLINE sdd1 ONLINE sde1 ONLINE sdf1 ONLINE sdj1 FAULTED corrupted data root@Diskstation:~#
October 26, 2025Oct 26 Community Expert The pool is damaged; this would not be caused by just doing a the new config, post the output from zdb -l /dev/sdX for all pool devices.

October 27, 2025Oct 27 Author I also changed the SATA controller beforehand, and everything ran normally afterwards. Then I wanted to replace the Force MP510 SSD and misread something, doing exactly the wrong thing in the new configuration. So, for the ZFS mirror raid ss.cache and for the ZFS raidz2 1vdev of 8 devices. I then imported the configuration file again and the ssd.cache was successfully recognized, but unfortunately not the zfs.spinner. Even though all 11 hard drives are displayed in the Unraid GUI, the command *ls /dev/mapper only finds 10 hard drives. See screenshot of the main GUI in Unraid. Here is my hard drive configuration. Oh, and they are all ZFS encrypted.

October 28, 2025Oct 28 Community Expert Just for the hell of it, also post the output from:zpool import -o readonly=on -f -F -n zfs.spinnersMost likely it won't be able to rewind, but it won't hurt to try.
November 2, 2025Nov 2 Author All right, thanks for your help and the information. Yes, I have a backup. First, I need to check what I set up for the backup back then and whether everything I need is there. Otherwise, I'll probably resort to klennet's solution or something similar and try to restore the pool with that. The price is high, but I haven't found anything cheaper. I'll run a test of the software to see what it can find and restore. Thanks
November 6, 2025Nov 6 Author Unfortunately, the software cannot find any data :/ I have now entered the above command to rewind, but nothing seems to be happening. So no output and no read/write access to the hard drives.I could send the hard drive that lost the partition to Seagate; maybe they can recover it. Data recovery is still included in the warranty.

November 10, 2025Nov 10 Community Expert It tried reqiendo to txg=2609492, but that is still too far away from the two devices with a much older one, I think data recovery app is the only possible route to try and recover some data from this pool.
