Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.
i don't get it synced again.
they are now both stand alone?
i can ping them both.
don't have any options left.

***************************************************************
DRBD's startup script waits for the peer node(s) to appear.
- In case this node was already a degraded cluster before the
reboot the timeout is 0 seconds. [degr-wfc-timeout]
- If the peer was available before the reboot the timeout will
expire after 0 seconds. [wfc-timeout]
(These values are for resource 'drbd'; 0 sec -> wait forever)
(i had to restart drbd on the second node)
To abort waiting enter 'yes' [ 54]:May 13 15:17:16 kvmstorage1 kernel: block drbd0: Handshake successful: Agreed network protocol version 96
