- From: Nikolaus Rath <Nikolaus@rath.org>

- Message-id: <20140811050553.7351.15739.reportbug@vostro.rath.org>
Package: src:linux
Version: 3.14.13-2
Severity: normal
File: /boot/vmlinuz-3.14-2-amd64
Hello,
I started a scrub of one of my btrfs filesystem and then had to restart
the system. `systemctl restart` seemed to terminate all processes, but
then got stuck at the end. The disk activity led was still flashing
rapidly at that point, so I assume that the active scrub was preventing
the reboot (is that a bug or a feature?).
In any case, I could not wait for that so I power cycled. But now my
file system seems to be stuck in a scrub that can neither be completed
nor cancelled:
$ sudo btrfs scrub status /home/nikratio/
scrub status for 8742472d-a9b0-4ab6-b67a-5d21f14f7a38
scrub started at Sun Aug 10 18:36:43 2014, running for 1562 seconds
total bytes scrubbed: 209.97GiB with 0 errors
$ date
Sun Aug 10 22:00:44 PDT 2014
$ sudo btrfs scrub cancel /home/nikratio/
ERROR: scrub cancel failed on /home/nikratio/: not running
[2] nikratio@vostro:~/tmp
$ sudo btrfs scrub start /home/nikratio/
ERROR: scrub is already running.
To cancel use 'btrfs scrub cancel /home/nikratio/'.
To see the status use 'btrfs scrub status [-d] /home/nikratio/'.
