ZFS 2.0.5 contains bugfixes for issues that hang ZFS threads and prevent send/receive from functioning (until the next reboot). Particularly (from the changelog):
Do not hash unlinked inodes #9741 #11223 #11648 #12210
It was released on June 23, 2021 and we're eager to get this change on to our systems. It doesn't appear to be available yet in any of the PVE repositories for Buster or Bullseye so this is just to highlight that there are important issues resolved by this release and to request a package update.
Thanks!
