Scrub does not fix the problem. I replaced the real host name with "myhost".
Strange for me: the mentioned pathes for errors point to the same file names,
just a part of the "myhost" is different.
The btrfsck fails with the same crash after the scrub.
speedy:/home/cv # btrfs scrub status /backup.old
scrub status for fa7034c8-86d4-4aa3-9fde-ecd7051ff43c
scrub started at Thu Jul 12 20:21:08 2012 and finished after 1495 seconds
total bytes scrubbed: 115.49GiB with 9 errors
error details: verify=3 csum=6
corrected errors: 3, uncorrectable errors: 6, unverified errors: 0
Should I continue with any analysis for bug hunting or just reformat and forget?
Best regard,
Christian
