Thanks. I might try putting the GFS1 in the kernel tree... but quite frankly, adding bits to the kernel without a patch is a bit beyond my talents.
I've been using GFS2 for a project for some time. It's GFS2 over DRBD. The system is production, but the GFS2 filesystem on it isn't. In fact, left mounted for a few weeks and untouched, it eventually zombies any process that tries to even 'ls' the filesystem... leading to a late night reboot. Granted, this project has had a lot of side tracking... such as being shipped out with a fubar L2 switch.
I am building a second cluster for a separate project, and I can be more daring with this until it has to go production... the reason I'd like to give GFS1 a try.
I have used DRBD for years... but GFS/Cluster is still new to me. To build the GFS2 volume, I followed the LinBit GFS2 documentation. I recently looked at some of the DRBD_Cookbook and I noticed it uses fencing, whereas LinBit's doc doesn't use it. My cluster.conf is short and sweet:
<cluster name="clust" config_version="1">
<clusternode name="clust1a" nodeid="1">
<clusternode name="clust1b" nodeid="2">
<logger ident="CMAN" debug="on" to_stderr="yes"/>
Have I followed an oversimplified path? Is it a case where I need the fencing as in the DRBD_Cookbook? From the perspective of the LinBit GFS2 doc, Cluster is only used to get the DLM and CLVMD running.
Thanks in advance.
