Hi Sandra, Lars,

    I have the same problem too:

May  6 09:24:49 server kernel: EXT3-fs error (device drbd(43,0)):
ext3_free_blocks: Freeing blocks in system zones - Block = 152, count = 1
May  6 09:24:49 server kernel: EXT3-fs error (device drbd(43,0)):

ext3_check_descriptors: Block bitmap for group 896 not in group (block
29261657)!

    but my configuration is very different!

I have master machine with 760Gb on RAID 1+0 by 3Ware controller, It's
LAN-mirrored with drbd version: 0.6.13 (api:64/proto:62) on slave machine
with 777Gb /dev/md0 on software-RAID 0.

I read Lars's suggest about hardware write cache on 3Ware controller and I
turn it off.
I have resolved this problem, so in my log file it does'nt compare more!

Bye, Alessandro
