You didn't mention XFS. Just curious if you considered it or not.
Most definitely. There are a few features that I'm looking for:
- MOST IMPORTANT: STABLE!
XFS is quite stable in CentOS 6.4 64bit. there was a flakey kernel issue circa 6.2.
- The ability to make the partition bigger by adding drives with very
minimal/no downtime.
XFS+LVM+mdraid does this, but it requires several manual steps...
I'd take the new drives, add them to a new md mirror, then add that md device to the volume group, then lvextend the logical volume, and finally xfs_grow the file system. yes, thats a bunch more steps than the zpool/zfs commands, but in fact zfs is doing much the same thing internally.
I believe lvm also lets you replace pv's in the vg with new larger ones. I haven't had to do this yet.
