Hi,
on a pair of Debian etch server (kernel 2.6.22-4-686) I'm using DRBD 8.0.12
(from the backports repository).
Yesterday I noticed that DRBD disconnected and went into StandAlone state and
I have no clue why this happened.
Below I'll include the relevant part of the syslog on both servers and my
drbd.conf.
Does anyone have an idea what happened?
Could this have been caused by a network disruption?
Why din't DRBD reconnect?
Thanks for all your help!
