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.
