Even if ZFS would be the only filesystem in existence i would make one per
2 disks (single mirror).
No matter what's going on, what do you prefer in case say - double disk
failure from one mirror on 48 disk systems?
losing completely data of 1/24 of users (and then restoring that amount
from backups), or losing randomly chosen 1/24 of files from whole system?
With UFS of course i would have single disk fsck time - less than a hour. which CAN be done
out of work hours with soft updates.
i normally turn off automatic fsck for large data filesystems, and if
crash happened i run it after/before work hours.
