Hello,
I've just completed a scrub on my home filesystem and now I wanted to start
on my Archiv btrfs RAID 0.

A scrub I started at Jan 02 seems to be stuck somehow. The command outputs
above were generated right now.
I'll be hapy to provide any more information.
Thx!

Amendment:
anything btrfs related dmesg shows is
[ 38.240950] BTRFS info (device sdd1): csum failed ino 314 off 4129595392
csum 1774389615 expected csum 2138618437

This messages are the reason why I wanted to try a scrub.

Scrub log record file seems corrupted sometimes, if you use latest
btrfs-progs version.
There should be an option '-f' for 'btrfs scrub start' which will allow
scrub to skip check in userspace.
Actually, i am thinking whether it would be better to remove userspace
check about
scrub status since log record file is not so reliable.
Thanks,
Wang

Thanks! Changing to canceled:1 in /var/lib/btrfs/scrubXXXfooXXX did the
trick. Last night the scrub finished successfully.
