Errors (re)createing zfs pool on OMV Version 7.5.0-1

theking2 · Jan 18th 2025

I attempt to recreate a ZFS pool

I formatted all the SSD in the old one
removed and reinstalled ZFS plugin
Attempt to create a pool results in:

(btw I cannot select my OMV version in the forum thread but it is what is listed on the System Information page)

Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LC_ALL=C.UTF-8; export LANGUAGE=; ls -la /dev/disk/by-id | grep 'sda$'' with exit code '1':

do you install proxmox kernel first like described here ??? : [HOWTO] Instal ZFS-Plugin & use ZFS on OMV

I see one problem here:

I didn;t (and I am not a beginner have been managing a zfs stack on Arch linux for 1.5 decade)

LIke I set. I had a pool installed did not do anything to the plugins removed the pool and wanted to create it again.

theking2 · Jan 18th 2025

I now see this has nothing to do with ZFS. If I shred /dev/sdd using the UI it starts shredding /dev/sdc.

This seem quite a harmful glitch.

I updated my question to reflect these new insights but wonder why raspbian not completely populates the /dev/disk folder even after a reboot.

Doing a manual shred of all the remaining ssd

I assume you have an RPi5 with a pcie to sata hat? Otherwise, usb is not support for raid including zfs. You do need to wipe the disks in order to create a new pool.

How did you "shred" it? If if was from the Storage -> Disks tab, I would like to see a screenshot with the Device Symlinks column enabled.

Yeah shred it with the shred command. or with UI using the eraser icon. Like I said this was a hardware problem. After setup I shutdown and moved the NAS to its final location dislodging some connection.
