Hello folks
supermicro x11ssl-f
Intel(R) Xeon(R) CPU E3-1280 v6
32GB ECC
1xNVME for apps pool
32gb SSD boot drive
tank pool with 4x 4TB HHD zfs2
datos pool 1x8TB HDD
truenas scale 25.04.1
I was very happy with my rock solid server, I left my google drive and google photos, trusted my fancy Nextcloud drive and installed a media server, vaultware, etc… It was working perfectly fine for a year or so… but the other day one of the hdds reported some problems, so I bought another drive, installed the new one, resilvered and two days later I reboot the system because I wanted to add a GPU for my media server.
The nightmare started after the reboot, because my pool tank had disappeared, all the 4 drives were exported and I can’t mount them again… ChatGPT had very good intentions and there is apparently a lot of knowledge behind… but it didn’t help me to solve the problem
I still can’t believe that a zfs2 can break so easily, it should have 2 redundant disks…

Please provide the output of this command, as formatted text (</> button):
lsblk -bo NAME,MODEL,ROTA,PTTYPE,TYPE,START,SIZE,PARTTYPENAME,PARTUUID
I assume that there is no SAS HBA or “PCIe SATA card”.
Have you checked cables (power and data)?

If you are going to import then you need to specify where it will get mounted. Usually you don’t need to tell ZFS where to look, but if you do then it needs to be by partuuid not by disk id. I suggest that you try the following and see what it says:
sudo zpool import -R /mnt tank
Also please run @etorix ’s command to give us details of what disks and partitions Linux can see.

admin@truenas[~]$ sudo zpool import -R /mnt tank
cannot import 'tank': one or more devices is currently unavailable
BTW, Could reinserting the old HDD that had caused problems before the resilver help?
Unless that drive is completely dead/causes system to hang/freeze or any other kind of degradation; yes, re-inserting the failing HDD can help.
Generally recommended (if possible/enough ports & introduces no additional faults) to keep all drives connected when replacing.

Please supply the output of the following commands for the 4 x 4TB disks;
zdb -l /dev/sda2 | grep txg: | grep -v create_txg:
zdb -l /dev/sdc2 | grep txg: | grep -v create_txg:
zdb -l /dev/sdd2 | grep txg: | grep -v create_txg:
zdb -l /dev/sde1 | grep txg: | grep -v create_txg:
They should all have the same ZFS transaction number. Let us see what the drives say they have.
Next, the disks should all have 4 labels:
zdb -l /dev/sda2 | grep labels
zdb -l /dev/sdc2 | grep labels
zdb -l /dev/sdd2 | grep labels
zdb -l /dev/sde1 | grep labels
i don’t get anything:
admin@truenas[/]$ sudo zdb -l /dev/sda2 | grep txg: | grep -v create_txg:
admin@truenas[/]$ sudo zdb -l /dev/sdc2 | grep txg: | grep -v create_txg:

Weird.
Can you get us the output of 1 disk, the supposed working disk?
sudo zdb -l /dev/sde1
i installed again the resilvered one and the output changes:
admin@truenas[/]$ sudo zdb -l /dev/sde1 | grep txg: | grep -v create_txg:
txg: 6606762

I’m not sure why the other 3 are not showing any data. But, without enough disks, (2 in a 4 disk RAID-Z2), that have valid ZFS header / label, the pool can’t be imported.
Perhaps someone else will be able to take this further.
@Jorge_Fernandez
Please run the following command to checks that device names didn’t change with a reboot etc.:
lsblk -bo NAME,LABEL,MAJ:MIN,TRAN,ROTA,ZONED,VENDOR,MODEL,SERIAL,PARTUUID,START,SIZE,PARTTYPENAMEsudo zpool import
Assuming that the disk names didn’t change please run the following and post the results (apologies but they will be lengthy):
sudo zdb -l /dev/sda2sudo zdb -l /dev/sdc2sudo zdb -l /dev/sdd2sudo zdb -l /dev/sde1
Then try the following in sequence and STOP immediately if any of them give no output and return straight to the command prompt:
sudo zpool import -R /mnt tanksudo zpool import -R /mnt -d /dev/disk/by-partuuidsudo zpool import -R /mnt -d /dev/disk/by-partuuid tanksudo zpool import -R /mnt -f tanksudo zpool import -R /mnt -f -d /dev/disk/by-partuuidsudo zpool import -R /mnt -f -d /dev/disk/by-partuuid tank
If any of these gave no output (so you stopped), then run the following commands:
`sudo zpool list -vL tank
`sudo zfs list -r tank
(Apologies for the multitude of commands but I prefer to ask for copious debug output all at once because it saves on the back and forth and can end up being quicker.)

Should I do this with the resilvered HDD or the defective one.
No - definitely do NOT put the old drive back in. Let’s try to stick to a fixed set of hardware and not try to chop and change.
RAIDZ2 should be able to survive this - we just need to work out how to import the pool. If you swap the drive back, then you will have one drive which is known failing and which has a very old TXG.
What’s on the datos pool?
it is just data I don’t need to secure with additional parity, like media…
I have doubled checked the connections, changed one of them…
After inserting the resilvered one, I realised during the boot process that it gives me the option to boot whit version 25.04.1 and with 24.04.2.1 and 24.04.2.2. I guess this is no important, but if nothing works maybe I could try…
BTW, the UI gives me the option of adding the 4 disks to a new pool:
Now, to your commands:

Ok - I think the reason it won’t import is that 1 of the drives (currently /dev/sdd - a Seagate ST4000VN drive with serial number ZW628JGE on the label) has a lower TXG than the other 3.
You have two choices I think:
Shutdown, remove the Seagate ST4000VN drive with serial number ZW628JGE, reboot and try to import the degraded pool using sudo zpool import -R /mnt -f tank. If that works, then you will have one drive marked unavailable. You need to clean the removed drive (someone will need to advise how to do it), before reinstalling it and using it to resilver the degraded RAIDZ2 back to full redundancy.
Try to mount the pool read-only with a roll-back to TXG 6590607 and then copy the data elsewhere before cleaning the disks and recreating the pool - but this is 16,000 transactions previous so the uberblocks may have wrapped around which means that some data freed up blocks may have been overwritten and you will lose the data written in the 16,000 transactions and there might be files lost too.
Obviously the first of these seems to be most sensible - but get a 2nd opinion on this.
