Hello,
Background:
First off, let me say thanks in advance and admit that I am a noob to NAS and zfs and undoubtedly broke rules in configuring things. I have TrueNAS running as a virtual machine in Proxmox and one day my server went down hard. I believe I had the pool imported in both Proxmox and TrueNAS (now I know better to use shares). After that, I could not get TrueNAS to boot because it fails to import the pool. At this point, I believe the pool to be completely broken and have no hope to fix it, but I would like to recover as many files as I can.
What I've tried:
I followed the steps here: https://www.truenas.com/community/threads/zfs-has-failed-you.11951/ to boot TrueNAS using Escape to Loader and boot to shell. I have then imported the pool using. The import succeeds, but I can't find any of the files in where I would expect them.
returns the following:
Attempting to mount without causes the zpool command to hang and nothing helps short of rebooting. I probably have killed the pool, but is there any chance to get my files back? I am confused about why the pool imports and reports ONLINE but the files are not there.
