Hello everyone,

I have a problem with starting the ZFS pool in mirror (where there are config, docker, vm, and some folders that haven't been backed up).

This is my system (now):

I successfully updated from version 6.12 to 7.1.4 last Thursday.

The pools all seemed fine after the update reboot. Subsequently, the parity check started and the web page was no longer reachable. I was also unable to access via ssh.

I powered off and restarted the server, and perhaps this was the problem.

The "WRONG CONFIGURATION" message appeared and the array did not start.

I did some research on the forum and found the following solution: - remove the pool - recreate it with the same name - reassign the devices - leave the file system set to auto - start the array.

I did this, now the system starts, but the config folders are moved to the HDD_CACHE pool, which doesn't have issues. Instead, the nvme_cache pool, where there are data and the cfg with docker and vm, gives an error of unmountable: unsupported or no file system.

I did this check anchd tried:

zpool status:

root@ISENGARD:~# zpool status

pool: hdd_cache

state: ONLINE

status: Some supported and requested features are not enabled on the pool.

The pool can still be used, but some features are unavailable.

action: Enable all features using 'zpool upgrade'. Once this is done,

the pool may no longer be accessible by software that does not support

the features. See zpool-features(7) for details.

Maybe the first disk (nvme0n1) now is corrupted. I've tried a switch drive (remove pool, assign the nvme1n1 on first and nvme0n1 on second) but notingh change.

I also another alert in gui popups

If unmount the array and remove the assign, i see a only one label of nvme1n1

I have a docker,vm backups but i didn't save the last data of few directory (about 65GB) of nextcloud directory into this nvme pool.

What i need to do now, for recover zfs pool and the system turn on work correctly?

Do I need to go back to 6.12? Am I at risk of not starting the entire array?

If it is not possible to recover the nvme_cache zpool, I could recreate it from scratch. I recover the folder that I did not save and easily restore the docker containers and the VMs?

Thanks Fabio

fdisk -l /dev/nvme0n1

This device is missing the partition, but something else is going one, since zpool import should still find the pool by the other device, post the output from zdb -l /dev/nvme1n1p1

For the other device, type sfdisk /dev/nvme0n1 then type 2048 and hit enter and post the results, don't type anything else for now

Thanks @JorgeB
i tried but nothing

root@ISENGARD:~# zpool import zdb -l /dev/nvme1n1p1

cannot import 'zdb': no such pool available

ZDB IS CORRECT?

I tried also

root@ISENGARD:~# zpool import nvme_cache -l /dev/nvme1n1p1

cannot import 'nvme_cache': no such pool available

Maybe i need to invert the disk ( nvme1n1p1 first and nvme0n1 second) ..

Or set ZFS RAID in mirror and not AUTO ?

The command is just this.

sfdisk /dev/nvme0n1

This one is also only this, only after hitting enter, do you type 2048 and enter again

Thanks @JorgeB , my wife distracted me for lunch lol

So it's no good?

Welcome to sfdisk (util-linux 2.41).

Changes will remain in memory only, until you decide to write them.

Be careful before using the write command.

Checking that no-one is using this disk right now ... OK

Maybe i need to try to load and mount the nvme1n1 in the first disk ?

I think that the nvme0n1 is corrupted

Not sure what happened to the pool, but I'm afraid it's gone, there's no zfs label on the device still with a partition, and there's no previous zfs signature on the device without a partition, so you will need to recreate the pool and restore the data from a backup, if there's no backup, you can try running a file recovery app like UFS explorer to see if it can still find anything.

Can i try to load nvme1n1 in a single pool (not mirror) ? It's a choice?

You can try, but it's not going to work since there's no zfs label on that device.

I try another check

Maybe only is working correctly now: nvme1n1 931.5G

└─nvme1n1p1 931.5G

So i think that i can work with this drive for recover data

Edited July 5, 20251 yr by Spa

@JorgeB i'm trying a trick, and recover some information
I download the lastest flash backup, extract and see some files

I Can see a pool cgf .. how can import in somewhere o something ? Can it helps?

Thanks

Also @JorgeB i did a mistake

i didn't export pool before remove and recreate!!

What can i do now?

@JorgeB ?

Restoring the pool cfg won't make any different, the command above shows that the zfs label is corrupt, you may still be able to recover some data with a file recovery app like UFS explorer.

It may also be worth trying the label repair option from zhack, but I have zero experience with that, though not much to lose at this point:

https://openzfs.github.io/openzfs-docs/man/v2.2/1/zhack.1.html

I've tried but nothing .. i check my backup and luckly i did a big backups 2 months ago .. it's good

In the end, i created new pool and restored all docker and data

I never did a VM backup :( so i'll create my two virtual machine

Thanks for help!!

Sorry @JorgeB ,

what it's safe to do for HDD_CACHE ?

in terminal, type zpool upgrade?

Thanks Fabio

root@ISENGARD:~# zpool status
