Subject: btrfs receive deadlock and questions
Date: Tue, 22 Jan 2019 10:24:32 -0500 [thread overview]
Message-ID: <CAJtFHURMDnM9EMAeLE4yr-UbWHa=o8M0=Yvm-MZp8ixWykfxFw@mail.gmail.com> (raw)
I seem to have it a deadlock trying out btrfs send & receive. Now I
haven't used btrfs send & receive much, so don't have much experience
with them. Anyways, bug report and stack traces:
https://bugzilla.kernel.org/show_bug.cgi?id=202383
Seems like the receive is hung as well as several kworkers. It's about
1.2TB into a 9TB or so transfer onto a brand new pretty empty fs. This
is just a btrfs send snapshot, not an incremental. That was supposed
to come next. If this was an rsync based backup I'd just kill the
rsync process and restart it, not sure if there's a way to restart a
btrfs send receive, or if I'd have to delete the partially created
snapshot on the destination and restart the send. I guess I could just
use rsync to finish the copy of the initial snapshot as well before
using send | receive for the incrementals. Thoughts and options would
be appreciated, thanks.
