Right, I can mount read only. Running a find command across the
filesystem, yields lots of:
[ 7775.228342] btrfs: corrupt leaf, bad key order:
block=756502351872,root=1, slot=1
type messages in dmesg, running a scrub gives:
scrub status for 7d65d152-1200-4043-981a-06757707f1ba
scrub started at Wed Jan 18 22:29:30 2012 and was aborted after 5575 seconds
total bytes scrubbed: 1.26TB with 0 errors
And in dmesg:
