<pre wrap="">Rois,
I don't have such sections on my drbd.conf is that relevant to
drbd 8.x perhaps. My versions are drbd 0.7.24 and heartbeat 2.1.2-3
I planned a downtime on Saturday during which I will try and see if I
can reproduce the fault again.
cheers

<pre wrap="">I'm using drbd 8 and don't know anything about 7 but part of what is in
these sections is the outdate-peer info. One of my initial problems
when I was setting up was that a failure would not fail over because the
secondary was being outdated (and thus not able to become primary) when
the primary failed. Someone who is more familiar with drbd 7 will have
to help you if this section is not important to drbd7.

<pre wrap="">I can fail over, and did plenty of tests with programs writing on the
shared nfs and rebooting the primary and they were all satisfactory,
but for Murphy's law (and perhaps cosmic rays!) for once that it had
to do it in production ... it failed!

<pre wrap=""><!---->When you say you did fail over tests do you mean you did
"heartbeat standby"
or did you actually pull the power plug or all the network cables? I've
noticed that the drbd/HA acts different when you do nice fail over test
(rebooting the machine or doing "heartbeat standby") as apposed to "down
right nasty" fail over tests (pull the power plug or all network cables
at once to simulate something very bad happening.)
I'm fairly paranoid about how stuff works so I like pushing the limit.

Rois, <br>
you're right I just tested standby and plain shutdown. I just
recently managed to acquire remote bios access to this machine, so I
will soon tell you (and the list) if this is replicable by resetting
the power.<br>
cheers<br>
