Hi,

i think my btrfs volume is hosed.... it mounts okay, but iostat shows /dev/sdg on \
100% load. dmesg shows lots of 'parent transid verify failed on x wanted y found z'. \
then after a while i can't read from it (access to the filesystem freezes).

the machine had crashed (prob from some other process), and upon reboot i've been \
experience this problem since.

can anyone provide any guidance in how to proceed?

cheers,

Yee.
