Many thanks for your advice. Definitely will have a look!

Any news on a function like this? I would like to delete a few older snapshots from my zfs disk in the array which causing very long mounting times when I reboot the server.

I believe the ZFS master plugin. I set everything up some time back. Maybe I should go ask in the ZFS master plugin thread rather than wasting your time

In the end I decided to just recreate the pools. Thankfully I had some partial backups of the VMs in this pool and I managed to have everything up and running almost as good as before. One of the things I found out though is that the array start up in my case takes too long. Disk 3 which is a zfs disk overall takes 50+ mins to be mounted. I don't know if its because it has too many snapshots (3000+) since it doesn't seem there is any other issue with it. Any idea how to remove some snapshots or how to decrease the frequency they are created?

Yes it was created with Unraid. I tried a couple of things but nothing worked for the cachessd pool. So I destroyed it and will rebuild it from scratch.

I entered this , took like 10 mins and came online. If not disk3 problem maybe its the cachessd pool zfs raidz1? I came across this topic Do you think it is a partition problem in my case as well? Even though the two bad disks aren't identical to the still working one? fdisk -l fdis If there is no other ideas I think I will try this solution

Hi everyone, hope you can help me fix the following issue. I had to shutdown my array today due to electrical work taking place, and the array isn't starting up anymore. It is stuck on mounting disks. I am attaching the diagnostics before I start the array. I don't see any issue on the log file. The process is stuck at trying to mount Disk 3 of the array. Disk 1 and 2 are xfs and Disk 3 is zfs. 8TB each. zpool import returns Which is strange since I didn't do anything to the cachessd pool which shows as unavailable. Any thoughts are more than welcome.

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

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?

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

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 to sdc1

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? hades-diagnostics-20231003-0713.zip

Did the migration to Nordlynx as well yesterday. Everything seems to work smoothly. I am using docker-compose.yaml for setting up my containers rather than the unraid gui.

Can you please give a few more details like a step by step guide? Or was it plug and play?

Updated to 6.9.1 as well and everything runs smoothly. As I can see the issue is resolved for everyone, so will be tagging this topic as solved.
