how to cancel scrub which got aborted due to hardly switching off the machine?

[Martin Steigerwald]

Hello,

I have:

merkaba:/mnt#1> btrfs scrub status -d /home
scrub status for […]
scrub device /dev/dm-0 (id 1) status
        scrub started at Fri Apr 18 17:48:10 2014, running for 335 seconds
        total bytes scrubbed: 74.80GiB with 0 errors
scrub device /dev/mapper/sata-home (id 2) status
        scrub started at Fri Apr 18 17:48:10 2014, running for 335 seconds
        total bytes scrubbed: 69.86GiB with 0 errors


merkaba:/mnt#2> btrfs scrub resume /home
ERROR: scrub is already running.
To cancel use 'btrfs scrub cancel /home'.
To see the status use 'btrfs scrub status [-d] /home'.


merkaba:/mnt#1> btrfs scrub cancel /home
ERROR: scrub cancel failed on /home: not running

merkaba:~> btrfs scrub start /home    
ERROR: scrub is already running.
To cancel use 'btrfs scrub cancel /home'.
To see the status use 'btrfs scrub status [-d] /home'.


merkaba:~> cat /proc/version
Linux version 3.14.0-tp520 (martin@merkaba) (gcc version 4.8.2 (Debian 
4.8.2-17) ) #52 SMP PREEMPT Mon Mar 31 13:41:48 CEST 2014


Seems like an logic error.

How to get out of there?


Thanks,
