I want a shared filesystem on top of drbd8 on two nodes. The servers run ubuntu 9.10.

I googled a lot, but couldn't find an clear trend what the web community prefers. It's seems that OCFS2 is more used at the moment.

Which filesystem is more reliable, faster? GFS2 or OCFS2? Is the linux community going more towards GFS2 or OCFS2? Which of this two is better supported by ubuntu 9.10?

Are there better (or more common) alternatives?
