A few weeks ago, I posted a how-to that details what it takes to get OCFS2 and Pacemaker to work together on CentOS 6.x. In this how-to, I want to show you how you can leverage that platform to deploy a scalable and performant NAS filer.
This filer will be integrated with Active Directory for the purposes of authenticating clients and provide three different services:
- SMB/CIFS
- NFS
- FTP
SMB/CIFS will be provided by Samba (3.6), NFS will be provided by Linux’s native capabilities and for FTP, we will rely on VSFTP.
One other thing of note about this how-to is that the cluster nodes will be using shared storage. If you want to use OCFS2 and Dual Primary DRBD, then check out clusterlabs.com. They have an excellent how-to on it.
Note: I’m assuming that you read my previous how-to and have that you’ve already installed the uek-kernel, pacemaker, ocfs2, corosync, resource-agents the other dependencies in addition to installing dlm_controld.pcmk. If not, you should follow through that document first.

Excellent.
But I would like to see a samba ctdb only from you.
Possible ? 🙂
I could, but samba already has a pretty good explanation of how to do it at ctdb.samba.org. Not to mention, there are many reasons why you would not want to run ctdb, samba and a cluster filesystem without a full blown cluster-stack.
Hi,
When I try and apply the CTDB patch i get the following:
[root@cluster1 heartbeat]# cat ~/ctdb.patch | patch
patching file CTDB
Hunk #1 succeeded at 78 with fuzz 2 (offset -3 lines).
patch: **** malformed patch at line 34: @@ -371,6 +391,11 @@
Any suggestions ?
I am using the latest resource agents from GIT as I am using GlusterFS instead of fighting with DRBD / OCFS2.
I am also running directly on Oracle Linux rather than Centos with the kernel patched in.
Your guide has worked for the majority of it so far with a few teeth gnashes between parts 🙂
Cheers,
Kane.
Hey thanks for the comment and sorry for any troubles. I tried to test as much as possible lol.
Perhaps its the formatting of the patch? Try this db link . Let me know if it works/doesn’t work for you.
If you have time to elaborate, I’d love to hear about any other frustrations or problems you experiences.
Thanks
That worked, thanks.
Most of my problems were getting the ocfs2_controld.pcmk to come up, it would install each time but pacemaker could never start it. dlm_docntold.pcmk was running but there was no /dlm for ocfs2 to attach onto.
Otherwise it was silly things like DRDB tools (8.13) and kernel mod (8.11) are different in Oracle so when you yum update you then have to downgrade the tools or exclude them from the update.
I have to document the build I am doing for work so I will drop you a copy of it, GlusterFS once running seems to have a lot less to go wrong but of course only time and testing will tell.
Cheers
Kane.
