I have a proxmox host with a single SSD and a zfs filesystem.

The pool was created when installing proxmox (v7) and the pool name is rpool. Yesterday, the host failed and I’m not sure how to troubleshoot it.

The error said there was an unrecoverable I/O error and rpool has been disabled. (Paraphrasing, because I’m on my phone)

I pulled the drive and made a raw copy on another system using dd. I was able to mount the drive externally via USB, import the pool, and also mount/import the raw image without any issues. Zfs status says the pool is online for both.

It’s been difficult to troubleshoot because I can’t get a prompt on the host machine. I’m a ZFS newb and not sure what to do next.

I have a spare SSD I can use if that helps.
