So zfs list shows: NAME USED AVAIL REFER MOUNTPOINT zroot 279G 6.75T 88K /zroot zroot/ROOT 1.74G 6.75T 88K none zroot/ROOT/default 1.74G 6.75T 1.74G / zroot/tmp 176K 6.75T 176K /tmp zroot/usr 277G 6.75T 88K /usr zroot/usr/home 276G 6.75T 276G /usr/home zroot/usr/ports 88K 6.75T 88K /usr/ports zroot/usr/src 670M 6.75T 670M /usr/src zroot/var 47.5M 6.75T 88K /var zroot/var/audit 88K 6.75T 88K /var/audit zroot/var/crash 88K 6.75T 88K /var/crash zroot/var/log 820K 6.75T 820K /var/log zroot/var/mail 46.3M 6.75T 46.3M /var/mail zroot/var/tmp 88K 6.75T 88K /var/tmp I had consultant configure another server for us. He set up the disk array with one dataset. so zfs list on this system give: NAME USED AVAIL REFER MOUNTPOINT zroot 2.65G 13.2T 2.62G legacy >From a sysadmin view I rather like the multiple datasets. Are there advantages to one over the other? _____ Douglas Denault http://www.safeport.com support@safeport.com Voice: 301-217-9220 Fax: 301-217-9277
