Hi guys. I have a backup server which is running a BTRFS raid10. This server is in the bedroom. So I have it set to suspend at night because of the noise, and then a systemd timer which resumes it at 07:00 a.m the next morning. As part of the suspend/resume script i issue a btrfs cancel before suspending and a btrfs scrub resume when the server wakes up again. I've noticed however that after a suspend the btrfs scrub resume doesn't seem to work properly. It just never finishes, even if the original estimate (before the resume) was roughly about 20hours, which it should have finished in one or two days. After waking up from a suspend, the btrfs scrub resume does indeed "resume" but it seems to have forgotten it's progress. It "looks" as though it just started over. Is this expected behavior or is it a bug? I'm running Debian Buster with backported Kernel 5.4.0 and btrfs version 5.4.1
