Hello Roland,
Sorry, I didn't attach it because it does not seem to have any relevant
information in it. But of course, here it is:

Hi,
can you provide the log (from the same connection attempt) from
the other node (primary) also?

I have two servers to host a website.
Only one is actively used at a time, the other one acts as hot standby.
All data ist replicated via DRBD from the currentlly active server
(primary) to the backup server (secondary).
I recently had to set up a new secondary, because the original one had
hardware problems.
So i followed the instructions in the documentation
(http://www.drbd.org/users-guide-8.3/s-node-failure.html#s-perm-node-failure).
The status of the primary node:
version: 8.3.7 (api:88/proto:86-91)
srcversion: EE47D8BF18AC166BE219757
1: cs:StandAlone ro:Primary/Unknown ds:UpToDate/DUnknown r----

ap:0 ep:1 wo:b oos:215272
The status of the secondary node:
version: 8.3.11 (api:88/proto:86-96)
srcversion: F937DCB2E5D83C6CCE4A6C9
1: cs:WFConnection ro:Secondary/Unknown ds:Inconsistent/DUnknown C r-----
ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f
oos:242699884
This seems to be all right.
But when issuing a connect on the primary it immediately disconnects again.
The log on the secondary has the following entries:

As far as i understand it, they do have a connection, agree on a
protocol, notice that secondary needs to be fully synced and then just
drop the connection for no apparent reason.
Can you tell me why this might be or where i can get further information
as for why the conenction is being dropped?
Thanks a lot
Koschi
