Starting DRBD resources: [ d(SERVICE) s(SERVICE) n(SERVICE) ].

***************************************************************
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 10 seconds. [degr-wfc-timeout]
- If the peer was available before the reboot the timeout will
expire after 20 seconds. [wfc-timeout]
(These values are for resource 'SERVICE'; 0 sec -> wait forever)
To abort waiting enter 'yes' [ 20]:

data01-P ~ # drbdadm connect SERVICE

data02-P ~ # drbdsetup /dev/drbd0 syncer -r 90M

data02-P ~ # dstat 1
