Subject: btrfs scrub: cancel + resume not resuming?
Date: Thu, 9 Jan 2020 11:03:08 +0100	[thread overview]
Message-ID: <CADkZQakAhrRHFeHPJfne5oLT81qFGbzNAiUoqb3r0cxVSuHTNg@mail.gmail.com> (raw)

Maybe I'm doing it entirely wrong, but I can't seem to get 'btrfs
scrub resume' to work properly. During a running scrub the resume
information (like data_bytes_scrubbed:1081454592) gets written to a
file in /var/lib/btrfs, but as soon as the scrub is cancelled all
relevant fields are zeroed. 'btrfs scrub resume' then seems to
re-start from the very beginning.

This is on linux-5.5-rc5 and btrfs-progs 5.4, but I've been seeing
this for a while now.

Is this intended/expected behavior? Am I using the btrfs-progs wrong?
How can I interrupt and resume a scrub?
