Hello all, Hope everyone is well and safe.
This is a plea to push along the resolution of this bug. I'm heavily invested in zfs and this has been a huge problem for me. Just like TimK I'm a sanoid/syncoid user and have seen the zfs recv problem. Changing syncoid's perl to not use "-s" worked for me. But thats not been an end to my problems. Originally I thought I had "lost" my main 10TB zpool for e.g hardware reasons, but its not proved simple as that. I can import and read from the zpool but see zfs timeouts regularly in syslog. If I try to write to this pool it hangs. zfs list hangs as well. Eventually zfs seems completely "stopped" and I have to reboot. Assuming my "tank" was trashed, I had been using my (syncoid) backups to reestablish my files in a new zfs pool on new hardware. Which worked fine (+1 syncoid). I've been trying to reestablish backups for my new pool/hardware this morning and find whereas I can zfs send a 4.8GB snapshot ok, I can not send a 7.2GB (or larger) snapshots - I get the rather anodyne message "Input/output error". I have also seen hangs when trying to zfs destroy snapshots on one of my other pools. Whether the hanging destroy is the root cause or just a casualty of other zfs stuff going on, I've no information. I realise that relating the generally instability of my system is pretty vague: its proving hard to pick apart the problems and demonstrate repeatable effects. So I'm eager to try the proposed fix but, as Jason has said, there is no amd64 version yet in focal-proposed. Can I encourage you to make the fix available please? Really appreciate everybody's effort.
