If I recall correctly, all nodes in your GFS cluster need to be on the same kernel rev, so mixing and matching FC4/5 might work, but I don't think this configuration is supported from Redhat or even something you might want to do later down the line. What exactly are you accomplishing by spreading the storage across multiple systems and using them in a GFS shared file system? It really doesn't sound like you need GFS here? Are you just trying to keep a copy of each code repository on each system and provide r/w access from each node? Unless you're using some kind of distributed source code revision system that will handle you're locking and consistency checking I wouldn't advise going down this route you are really just increasing your chances of file/data corruption. If bandwidth isn't a concern I would go with either NFS, or dedicated iscsi LUNS to each host not under a shared fs. -----Original Message----- From: linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of HAWKER, Dan Sent: Wednesday, August 30, 2006 7:39 AM To: (linux-cluster@xxxxxxxxxx) Subject: GFS Based File Server Advice Hi All, I have a new iSCSI array arriving soon and would like to carve it up and use GFS to provide a central storage pool for a group of servers we use for building/compiling software. Each team of developers only has access to their own specific build server and as such I don't need the servers to *act as one* however as they all use a common data snapshot, a cluster FS would seem a sensible direction to take. My developers are coding an unholy mix of Java, C & C++ in the main, and although they access the data snapshot simultaneously (presently spread across a couple of servers and dragged around using NFS) they rarely, if ever are reading/writing the exact same part of the data store at the same time. They use a view of the snapshot (in essence a duplicate), edit/write/etc the code, build and then submit it back to our versioning software (Rational ClearCase) which is stored elsewhere. After reading through the docs and other resources, it seems GFS would be a good fit, what with us running a mix of FC4/5 and RHEL4 boxes. Having read through the docs and stuff it all looks pretty straightforward, however thought I'd ask some advice to check for any gotchas and general *that didn't quite work as anticipated* experiences from ppl that I presume use GFS on a daily basis, and hopefully anecdotes from ppl who use GFS in a software development role.
