Hi Gianluca,
I'm pleased to announce I now have it working Yay!!!
Turns out the DRBD configuration was just fine.
I was a combination of using the right resource type (postgres-8) and the
order/dependencies of the resources.
Thanks for your help!!!
Here's my cluster.conf and drbd.conf for a
Hi!
I have a very strange performance issues with DRBD. I have two DRBD
nodes - nasnode0 and nasnode1. They are running two raid 10 with 4 sata
disks, and 1 raid10 with 6 sata disks. All volumes are exported via
iSCSI (ietd) to client servers. Client server run Xen vm's.
Now, my problem is that w
Thanks for your reply. I did try the built-in ocf script but ran into some
problems early on. Now that I understand some of this a little better, let me
go back and try it again.
I just wanted to make sure that it's not something I did wrong with DRBD.
Thanks for helping me understand. I'll g

Here's the data from the kernel panic - I'm not sure where the core

Hi Gianluca,
You have described exactly what I'm doing to test this. I kill the postmaster
process. I've tried both a script resource as well as a postgres-8 resource
but neither seem to work. What's odd is that I can relocate the service to
either node without issue. It's only when I "Brea
Can we please get a complete stack trace?
Thanks.

As a followup, I tried different versions of DRBD on the Xen machines,
and was able to get it working with DRBD 8.3.2 and earlier. 8.3.3 and
later causes the kernel panic.
Were any changes made to DRBD from 8.3.3 onward that causes problems
with Xen? Are there parameters I need to set?

Right.. what is the card? If Ethernet, no problem.

We are using DRBD v8.2.6 and recently ran into an issue where the primary and
