Hi all,
If you have had experience hosting GFS/GFS2 on CentOS machines could you share you general impression on it? Was it realiable? Fast? Any issues or concerns?
I've only run GFS2 on RHEL5. It's been quite reliable, but certainly has a bit of a learning curve from regular filesystems.
It's fast enough, but if you have more than one node, keep in mind you'll potentially be held back by lock manager contention under certain workloads (like reading information on every inode on the system for backup purposes, etc).
For our uses (home directory server), it's more than adequate.
Also, how feasible is it to start it on just one machine and then grow it out if necessary?
Haven't yet done this, but it can run on top of LVM just fine (clvm in fact).
Thanks.
Boris.

Thanks Ray!
Is it feasible to export GFS to NFS clients?
And one more interesting thing. Wikipedia ( http://en.wikipedia.org/wiki/Global_File_System ) says that GFS2 is supported only starting at kernel 2.6.19 but on my CentOS 5.5 uname says:
[bepstein@dellnikon ~]$ uname -a Linux dellnikon 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:35 EDT 2010 i686 i686 i386 GNU/Linux [bepstein@dellnikon ~]$
Could thins be a problem?
Boris.
