LVM2 is really your best choice. ZFS is only supported via FUSE, and unlikely to ever be ported directly to the linux kernel mostly because of license issues, but certain design incompatibilities as well (crossing linux's device and filesystem abstraction boundaries). LVM'd drives work well. I heartily recommend it. Further, building ext3 filesystems on top of LVM allows online addition of device and online growth of the ext3 filesystem. - -- Pat Eric Chevalier wrote: > Hello, fellow Linux/390 list members! > > The company where I works runs a mainframe Debian system for a variety > of functions.
