[Linux-cluster] EXT3 or GFS shared disk

[James Marcinek]

I forgot to turn on clvmd but now that I do I'm getting some 'Call Trace' issues...

I'm running 5.3 and it gave me a locking issue and indicated that it couldn't create the logical volume. However it showed up and I had some issues getting rid of it.

I couldn't get rid of the LVM because it couldn't locate the id. In the end I rebooted the node and then I could get rid of it...

I would prefer to use logical volumes if possible. The packages are there, one of the nodes did have an issue with the clvmd not starting...

I'm working on rebuilding the cluster.conf. It kept coming up as in the config but 'not a member'. When I went into system-config-cluster on one node it showed up as a member but not the other. Went to the other node and the same thing, it was a member but not the other.

Right now, I've totally scratched the original cluster.conf. I created a new one and copied it to the second node. started cman and rgmanager and the same thing they both are in the configs but only one member in the cluster management tab...

What's going on?

what grief did it give you? also- what version of RHEL are you running?

5.1 has some known issues with clvmd
