Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

I have replaced all hard-drives on the first server and upgraded DRBD
kernel modules to 8.3.15. I do verifying every week. It usually founds new
out-of-sync sectors, then I check if they are false-positive or not (with
md5sum) and find that 95% of them are real.
Could anybody suggest a way to debug? Can it be DRBD + RAID problem? Or
DRBD + one specific RAID problem?
