Ocfs2 users - Nov 2005 - OCFS2 for webhosting?

I'm looking at getting some sort of shared storage with a GFS-style
filesystem on top of it, so I have no single point of failure or
bottleneck like I would using NFS (and have suffered from so far) - is
OCFS2 stable? Does it make much sense to use for this?

Right now I have 4 web nodes. Eventually that could grow to 20, who
knows, maybe more. I'd love to use Coraid's ATA-over-Ethernet storage
as well. Perhaps it does not properly support the semantics required
by OCFS2 though (see this thread[1] saying that it doesn't allow for
multi-path I/O which I believe OCFS2 would require?)

iSCSI would be the next option, just have to find good pricing on
that. The assumption is redundancy and scaling would be handled by the
hardware (so there would be no SPOF or performance bottleneck there to
have to rely on software to fix)

Thanks for any info

Hello,

What about coda or AFS network file systems. If you dont need
synchronous locked file access i consider this much better than the
hardware you will need for SAN filesystems.

BTW: iSCSI is also SPOF unless you have NAS Systems which support
failover. But in that case you could use NFS (2 NetApp Filers for
example).
