since my last debian kernel-update to 2.6.38-2-amd64 i got troubles with
csum failures. it's a volume full of huge kvm-images on md-RAID1 and
LVM, so i used the mount options: 'noatime,nodatasum' to maximize the
performance.
it happened two weeks ago for the fist time. and now again a kvm-image
isn't readable again. i have to use an older snapshot to substitute the
virtual machine.
this are the entries in dmesg/kernel-log on any access:
...
[2412668.409442] btrfs csum failed ino 258 off 2331529216 csum
3632892464 private 2115348581
...
it's a production machine, so i can not make to much experiments on it.
do you see an obvious way to solve this problem?
thanks!
martin
