zpool recovery from possibly formatting hard drives while installing Proxmox

[jwebb48111]

Hello, I’m trying to see if there are any good ZFS recovery options out there for the home user. I have been running TrueNAS core at home since the FreeNAS days with no issues. I have two zpools, one mainly used for backups and the other for general use, both setup with RAIDZ1. I have been wanting to tinker with VM’s on TrueNAS but haven’t had much luck running Windows in Bhyve so I thought I would try Proxmox with KVM and TrueNAS as a VM with a PCIe pass-through for the HBA for the zpools. I exported both zpools while in baremetal TrueNAS before I begun. Instead of disconnecting the HBA with the zpools like I should have I left them connected when I installed Proxmox 7.0. I believe one of two things happened. Either Proxmox relabeled the IDs on my zpool hard drives or somehow I installed Proxmox in RAID 1 across two 256GB SSDs plus 12 spinning hard drives or something in between the two scenarios happened. I have ran zpool status and zpool list commands in the shell but the two zpools do not show up. When I list available hard drives to create a new zpool the hard drives in my damaged pools I would like to recover are listed as options to create a new zpool. To try and fix this problem I’m running TrueNAS on baremetal. I’m open to suggestions on if there is a way to retrieve the zpools or commands I can run in TrueNAS shell. Trying to explore all possible options I have only found software options of UFS Explorer, ReclaiMe Pro, and Klennet ZFS Recovery.

Go to shell and try first:

zpool import

That way all HDDs are scanned for pools. If possible you can than import the pools.
If nothing is listed a recovery is probably not possible.
