Not better ... I just suggested this being conservative and cautious. With a classic root-fs things would be splitted ... if the root-fs breaks or I need to use some live-media to fix things this would all be non-zfs-related operations. In the specific case I am still unsure if I want to use zfs at all. And I could suggest the customer a test-phase ... if it is not working as intended I could easily roll back the 6 disks to an LVM-based software RAID etc (moving data aside for the "conversion"). I am hesitating because I don't have zfs anywhere productive at customers ... only for my own purposes in the basement where there is no real performance issue. And the customer in case wants reliability ... ok that would be provided by zfs but I am not as used to admin that as I am with "native linux file systems". It also leads to other topics ... I can only backup VMs via LVM-based-snapshots (virt-backup.pl) when I use LVM, for example. rootfs on ZFS or "everything on ZFS" would have advantages, sure. No partitioning at all, resizeable zfs-filesystems for everything, checksums for everything ... you name it. In my case I have to decide until Sep, 25th -> installation day ;-) Stefan
