Our company is in the process of moving the production server data on a
enterprise storage servers and therefore we are considering which setup
would have the best performance and stability at the same time. Our
preliminary tests showed us that, at the filesystem level, XFS performs
best. Unfortunately, to be capable of growing the volumes we need to add
another layer - the volume manager. This increases the chances for
something to go wrong.
As I've read through the mailing list and other sources, there are only two
possible software packages on Linux - LVM and EVMS. From what I've read I
understood that LVM 1.x is feature-frozen and maybe even bugsolve-frozen in
favor of LVM2 development (see the deadlock while using xfs_freeze issue).
LVM 2.x is unstable beta and EVMS is so fresh that no real experience has
been heard of.
I understand that there's no bug-free software and no guarantee of anything
but maybe some of you have some enterprise-level experience with, say, 2+
TB data pool on XFS and some volume manager. I appreciate any reference of
any kind, some known imcompatibilies, what mistakes to avoid.. it would
help me a lot.
With best regards,
