Hi All,<br>
<br>
I've run into some problems on my DRDB cluster this week. This
cluster has been running fine for over a year. All of a sudden the
secondary failed:<br>
<br>
Jan 14 08:37:58 data2 kernel: [4895290.318176] drbd r0: meta
connection shut down by peer.<br>
Jan 14 08:37:58 data2 kernel: [4895290.318361] drbd r0: peer(
Primary -> Unknown ) conn( Connected -> NetworkFailure ) pdsk(
UpToDate -> DUnknown ) <br>

Jan 14 08:38:07 data2 kernel: [4895299.002852] drbd r0: Starting
asender thread (from drbd_r_r0 [3400])<br>
<br>
It would reconnect, sync, and disconnect again. I stopped the node,
checked the hardware (all seems fine), rebooted and tried to start
drbd again:<br>
<br>
root@data2:/var/log# drbdadm connect r0<br>
r0: Failure: (158) Unknown resource<br>
additional info from kernel:<br>
unknown resource<br>
Command 'drbdsetup-84 connect r0 ipv4:172.16.0.2:7789

<br>
My resource is:<br>
<br>
resource r0 {<br>
on data1 {<br>
device /dev/drbd0;<br>
disk /dev/sda1;<br>
address ipv4 172.16.0.1:7789;<br>
meta-disk internal;<br>
}<br>
on data2 {<br>
device /dev/drbd0;<br>
disk /dev/sda1;<br>
address ipv4 172.16.0.2:7789;<br>
meta-disk internal;<br>
}<br>
}<br>
<br>
And yes, /dev/sda1 does exist.<br>
<br>
I tried different things, I've updated to 8.4.7-1 (It was running
8.4.5), but I can't get it to work. I'm kind of stuck here - I have
no idea what is going wrong here. Any help would be greatly
appreciated.<br>
<br>
Kind regards,<br>
<br>
Dirk<br>
