I do not use any reservations but compression is enabled. Due to the raidz with 4 disks, I would expect zfs list to say 150GB * 75% = 112.50GB free, not 47.1GB. Can someone explain where the 65GB have gone? uname -a: FreeBSD ludde.dyndns.org 8.2-RELEASE FreeBSD 8.2-RELEASE #0: Thu Feb 17 02:41:51 UTC 2011 root@mason.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64 zpool list: NAME SIZE USED AVAIL CAP HEALTH ALTROOT tank 5.44T 5.29T 150G 97% ONLINE - zfs list: NAME USED AVAIL REFER MOUNTPOINT tank 3.96T 47.1G 28.4K legacy tank/data 3.95T 47.1G 3.95T /data ... other file systems omitted ... zfs list -t snapshot: NAME USED AVAIL REFER MOUNTPOINT tank/data@2011-08-05 385M - 3.60T - zpool status: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 raidz1 ONLINE 0 0 0 gptid/da8c85e1-f9fa-11de-a19c-001731eee65f ONLINE 0 0 0 gptid/db86c6a9-f9fa-11de-a19c-001731eee65f ONLINE 0 0 0 gptid/dc4efa95-f9fa-11de-a19c-001731eee65f ONLINE 0 0 0 gptid/dcd40f4a-f9fa-11de-a19c-001731eee65f ONLINE 0 0 0 Thanks, Ludde
