I hadn't turned on my NAS system for some time, and something regarding ZFS broke when I turned the system back on.
The setup for my ZFS pool is three 8TB drives in RAIDZ, with an NVME drive containing a ZIL slog partition and a cache partition. When I checked the drives in gparted, the ZIL log partition was somehow deleted and listed as unallocated.
From what I researched, it looked like the partition table for the pool was stored on that partition, so the pool no longer appears in the zfs/zpool programs.
My best guess is to try to recover the partition table for the ZIL log partition, which should restore the ZFS pool partition table with it, but I don't know of a safe to do this without risking losing the ZFS partition table. Would should I try to fix this?
