Can I use an existing partition and setup ZFS on this partition using = a standard Zpool (no RAID).=20 2. Should I use any other solution in order to setup this (like full ZFS = install on disk using the entire pool with ZFS).=20 3. Should I avoid using ZFS since my system is not well tuned and It = would be asking for trouble to use ZFS in these conditions.=20 P.S. Stability is a must for this system - so I won't die if you answer = "3" and tell me to keep on using UFS.=20 Thanks.=20 ________________________________________________ =AB?=BB=A5=AB?=BB=A7=AB?=BB=A5=AB?=BB=A7=AB?=BB=A5=AB?=BB=A7=AB?=BB=A5=AB?= =BB=A7=AB?=BB=A5=AB?=BB=A7=AB?=BB=A5=AB?=BB=A7 =AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF= =AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF BSD - BSD - BSD - BSD - BSD - BSD - BSD - BSD - ________________________________________________ =AB?=BB=A5=AB?=BB=A7=AB?=BB=A5=AB?=BB=A7=AB?=BB=A5=AB?=BB=A7=AB?=BB=A5=AB?= =BB=A7=AB?=BB=A5=AB?=BB=A7=AB?=BB=A5=AB?=BB=A7 =AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF= =AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF=AF PGP ID --> 0x1BA3C2FD
