Isn't that a bit apples and oranges? Ceph is a network distributed
thingy, not a local solution.
I'd use linux/software raid + lvm, it's the only one supported (by
CentOS/RedHat).
ZFS on Linux could be interesting if it was supported by Cloudstack, but
it is not, you'd end up using qcow2 (COW) files on top of a COW
filesystem which could lead to issues. Also ZFS is not really the
fastest fs out there, though it does have some nice features.
Did you really mean raid 0? I hope you have backups. :)
