I just started planning for a HA cluster system now. I want to
setup a HA file server that have its file shared to several
other server (planning for load balancing). Therefore I will
need a network / distributed file system that can work well with
certain replication system (either DRBD, rsync / csync, or even
better if it come with the file system).
My big question now is what network / distributed file system to
use? I did some research and came with some alternative, would
you mind give some comment on them?:
1. NFS, most commonly use, most flexible in setup. Issue: prone
to stale file handle, which will happen in failover situation.
Anybody know how's NFSv4 in this issue?
2. OpenAFS, good and secure network fs. Issue: some old design
problem, like only 15 characters per directory entry. No idea
how it will work with replication and how it will react in
3. PVFS2, need to learn much more about this.
4. GFS on the top of GNBD or iSCSI. No idea about performance.
Will it run on DRBD? I guess file-level replication is out of
the question. No idea how it will react in failover.
5. Lustre. Issue: the disk cannot mount locally / through local
loop, at least not recommended. Will it run on DRBD? I guess
file-level replication is out of the question. No idea how it
will react in failover.
6. Coda (or InterMezzo), actually ideal concept, replication and
network / distributed file system in one. But it apparently it
is not stable yet.
7. OpenSSI. Issue: distribution in limited form: in full kernel
and few of them. Kind of bad if I need to change kernel.
8. any thing else?
Thank you for reading this far!
