Hello everyone,
first time poster and novice Proxmox user
The story from the begining:
I was trying to decrease the root space of an LXC by
Backup - destroy - recreate from backup
And that succeeded without a hitch, the issue was that i had a ZFS mounded to the LXC and the data is now gone.
PANIC
The zfs "tank" is still mounted on Proxmox but no data
I tried using this guide https://endlesspuzzle.com/how-to-recover-a-destroyed-dataset-on-a-zfs-pool/
I found the txg tag to be 97914
But it was not possible to recover from that point.
Is there anything to do, or am I screwed?
