Hi,

 

I just recently setup an Openfiler 1.1.1 cluster using two IBM X345 servers and 6x 146GB RAID 5 disks in each one.  I used the Openfiler HA and Replication Howto, which by the way, isn’t anywhere on this site, but I was somehow able to find it in a google spider cache of sources.voluna.com.

 

Could you please publish that document somewhere?  It’s the only setup instructions I was able to find for Openfiler and DRBD/Heartbeat.

 

I wanted to provide some feedback, because there are some areas of this document that are wrong or out of date.

 

-          In section 2.1.4, step 5, I had to reboot the server before I was able to do a “drbadm adjust vg0_drbd”.

-          In section 2.1.5, the Heartbeat configuration asks you to put your files in /etc/ha.d directory.  The default configuration of heartbeat that comes with Openfiler 1.1 has heartbeat look at /usr/local/etc/ha.d for configuration files.  This problem is compounded by the fact that the /etc/ha.d/resource.d/drbddisk file is NOT located in /usr/local/etc/ha.d/resource.d.  In order to fix this, I had to copy /etc/ha.d/resource.d/drbddisk to /usr/local/etc/ha.d/resource.d/, then delete the /etc/ha.d directory and symlink /usr/local/etc/ha.d to /etc/ha.d

-          In section 2.1.8, step 6, the order for symlinking is backwards (I think).  Either it’s backwards, or every other symlinking instruction is backwards.  I think the intent is to have all other configurations pull from /cluster_metadata, while the rsync.xml file is actually pulled from /opt/openfiler.local/etc on each node (unique file on each node).  Is this correct?

-          I also had to manually create an /etc/ha.d/haresources file.  It got overwritten by openfiler at a later date, but in order to start heartbeat properly, I had to do this.

 

Things I’m confused about:

 

-          Openfiler wants to build its own haresources file, which is fine, but when I overrode my default Netbios name in Samba config (gave it a name that is assigned to the floating IP address of the cluster) it screwed up my haresources file by changing that to the same field as my Netbios name.  Is there a way to prevent this?  I want the Netbios name to be generic (not tied to either node name), so that it can failover properly.

-          How do I manually failover from one node to the other in order to do maintenance?  How do I failback?

 

I’m new to heartbeat and drbd, but so far it seems to be working ok.  Thanks in advance for your help.
