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

Logically, the above cases (reiser and swap verification errors) will only 
happen if DRBD and swap/reiser are being managed by the same kernel?

In other words, mismatches shouldn't happen if:

1) we run DRBD on one machine
2a) other machines access DRBD via iSCSI or other means, and write swap/reiserfs 
on it.
2b) other machines are being virtualized (Xen, VMware, KVM, etc.) on the machine 
running DRBD, and these virtual machines access DRBD
