Suddenly my home zfs became inaccessible. When I try to ls a specific directory, no response is returned forever. zpool status/scrub is no longer responsive as well.
After some trial and error, I was able to recover using zpool export/import. I checked every errors with zpool scrub, fixed them, and took a backup again. I’ve observed just 1 file has been corrupted, but it was scratch for tempolary use and not critical for me.
