[Ocfs2-users] ocfs2 hangs during webserver usage

[jmoseley at corp.xanadoo.com]

As others have indicated, I don't think that's going to work very well.
You've got two different nodes trying to write to the same file constantly.
I would keep each server's log on a locally mounted file system, or simply
keep the logs on the OCFS2 filesystem, but have each node write to
different log files.

Yeah, that makes parsing access_logs slightly more of a problem for
producing hit reports, etc, but I think you'll notice performance improve.

Yes, that is the case, multiple nodes with the same log file open &
being written to at once.

Worked well during all my testing environment stress tests, and even
worked great in production for over a month.
