Subject: btrfs scrub process prevents system suspend
Date: Thu, 20 Mar 2014 16:21:31 +0100 [thread overview]
Message-ID: <20140320152131.GA1172@asusntb.lan> (raw)
[-- Attachment #1.1: Type: text/plain, Size: 406 bytes --]
Today I accidentally discovered that it is not possible to suspend (hibernate)
the system while the btrfs scrub process is running (see the attached log).
Could this be considered a bug, or did I miss something?
Some more info:
$ uname -a
Linux asusntb 3.13.6-1-ARCH #1 SMP PREEMPT Fri Mar 7 22:47:48 CET 2014 x86_64 GNU/Linux
and btrfs-progs-3.12 is installed.
Regards,
Jakub Klinkovský
