Looking for advice if anyone has it as to how I can recover my filesystem after being affected by this bug. I installed zfs 2.0.6 via dkms and have moved affected files like my chrome cache to a quarantine location as suggested by Trent. However, I seem to continue stumbling on affected files, and even with /sys/module/zfs/parameters/zfs_recover=1 set I see panics in dmesg and hung processes that cant be killed.

From what I've gathered:

Running 2.0.6 via dkms means that I'm not running the affected code anymore. However, it seems like there is permanent FS corruption (which is very unfortunate since this is the sort of thing ZFS is supposed to be good at preventing).

Is there a best course of action to prevent future kernel panics? Would reverting to a snapshot from before I noticed this issue work, or is there shared metadata that's been corrupted? Should I just copy the files I can access onto another disk and re-create my ZFS pool / dataset?

Any advice is appreciated :/ Thanks
