Could someone share their knowledge and experience with CentOS and Ubuntu server management, maintenance capabilities and community support? I would be running pacemaker cluster and LAMP stack on it with GFS2 (or OCFS2) and other services.

Currently I have Gentoo system and I am almost happy with it but now I consider moving my applications to cluster system and I think that Gentoo is sometimes "not reliable" for maintenance.

So... Which should be easier to manage and more reliable distribution in my case?

IMHO, Ubuntu would be easier to manage. The community is pretty strong, Canonical Inc put enormous efforts to fix bugs and provide support. They are also ahead in their software versions - most of Ubuntu packages are newer than the ones in RHEL/CentOS. However, GFS/GFS2 comes from Red Hat, so presumably CentOS should be better with it. Red Hat backports new features in its kernel (TRIM for instance). CentOS 6 came with very long delay, compared to the previous CentOS releases. Also, RHEL is up to 6.1 since May 2011, no signs from CentOS about it.

Personally, I switched from CentOS 5.5 to Ubuntu 8.04/9.10/10.04. I am happy with it.

Just my $0.02.
