Reboot loop,Unable to mount the pool as rw

TrueNAS General

Sorry for just creating an account and jumping in like this — I’ve been a long-time lurker, first-time poster.
OS: TrueNAS scale 25.04
Host: Proxmox Virtual Environment 8.4.1
After a large write operation, the system became unresponsive. Upon reboot, it entered an infinite reboot loop. The serial shell output displayed the following error:

I’m able to mount the pool in read-only mode, but attempting to import it normally causes the system to enter an infinite reboot cycle.

My goal is to recover the pool so that it can be used normally again.

You need to describe your Proxmox settings for your TrueNAS VM, especially how you have PCIe passed through the disk controller and the disks and whether you have blacklisted the disk controller.

My advice is NOT to try to resolve the disk import issue until we have discovered what is causing the pool to become exported.

Please run the following commands in TrueNAS and post the results for each in a separate </> box:

  • lsblk -bo NAME,LABEL,MAJ:MIN,TRAN,ROTA,ZONED,VENDOR,MODEL,SERIAL,PARTUUID,START,SIZE,PARTTYPENAME
  • sudo zpool status -vsc upath,media,lsblk,serial,smartx,smart
  • lspci
  • sudo sas2flash -list
  • sudo sas3flash -list
  • sudo storcli show all

I have no idea whether the above commands will work in Proxmox, but if they do please run them there also and post the output.

Sorry for the late reply. I wasn’t near the device, and I had shut it down remotely, so I only just got the chance to operate it now.

Ok - I can see your boot disk in this Proxmox configuration, but I can’t see anything relating to passing through disk controllers or disks, or blacklisting the controller to stop TrueNAS ZFS pools being imported by Proxmox.

I just spotted this. I think this is good news because it suggests that the pool should be fixable. Fixing issues of mounting datasets is easier than fixing corruption inside the pool, and it is perhaps this that is causing the boot loop.

I would suggest that you mount it read-only again so that you can run diagnostic commands against it, and then run the following commands to try to see where ZFS is trying to mount the pool:

  • /sbin/zpool list -vL zpool
  • /sbin/zpool get altroot zpool
  • /sbin/zfs list -r zpool

(As an aside, calling a pool “zpool” is not a great idea IMO - I don’t think it should cause any technical issues, but since it is also a ZFS command it could create confusion.)

I passed through the entire SATA controller via PCIe passthrough.However, the controller has not been blacklisted in PVE yet.

Check your Proxmox host using zpool status to ensure that it did not attempt to (or successfully did) import your pool. If it has, you may be in a pool rollback scenario.

10

Reboot and do the import again only this time:

sudo zpool import -R /mnt -o readonly=on zpool

and then:

/sbin/zfs list -r zpool

11

Proxmox did not perform the import. This access happened because the original TrueNAS system fell into an infinite reboot loop, so I reinstalled the boot drive.

13

That looks correct.

14

With all due respect, how do you know?
Proxmox has the capability of importing zfs pools with no user input.

Checking the status @HoneyBadger mentioned is a good idea.

15

But I still can’t import the zpool through the web UI.

16

Alright, but after passing through the PCIe device once, the disk was no longer visible in Proxmox. Since I didn’t reboot Proxmox during the time the bug occurred, I believe it’s unlikely that the disk was imported by Proxmox.

17

They want you to check the status in Proxmox using the CLI. If it’s found Proxmox did ‘touch’ it, @HoneyBadger will need to walk you through the rollback attempts for TrueNAS

18

I hope you can provide specific commands to help me check my Proxmox system.

19

If I attempt to import with read-write access, the TrueNAS system will reboot within a few minutes.
