Hi, I'm doing the following actions on my solaris 10 system. Please let me know
if zfs will do the following things: -
Question1: - Will zfs employ ordinary raid0 stripes while creating the file
dust?
Question2: - Since most of my file /exp/dust1 (~74% = 1 - 400MB/1500MB) reside
on /tank/mnt-pt/file4, will zfs employ stripes while creating this file?
