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

you say above "sda4", now it is "sdb4" ?
why are you fsck'ing sdX, not drbdY ?

hard to tell.
I'd say, most likely due to the "hard reboot", whatever that means.
do your disks use volatile write caches?

since you fsck'ed the lower level device, thus modifying the data
bypassing DRBD, you absolutely need a full sync now.

on the node you want to be sync target,
say "drbdadm invalidate $resource"
