Maybe a basic zfs question ...
I have a pool:
# zpool status backup
pool: backup
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
backup ONLINE 0 0 0
mirror ONLINE 0 0 0
c1t0d0s1 ONLINE 0 0 0
c2t0d0s1 ONLINE 0 0 0
raidz2 ONLINE 0 0 0
c1t1d0 ONLINE 0 0 0
c1t2d0 ONLINE 0 0 0
c1t3d0 ONLINE 0 0 0
c1t4d0 ONLINE 0 0 0
c1t5d0 ONLINE 0 0 0
c1t6d0 ONLINE 0 0 0
c1t7d0 ONLINE 0 0 0
c2t1d0 ONLINE 0 0 0
c2t2d0 ONLINE 0 0 0
c2t3d0 ONLINE 0 0 0
c2t4d0 ONLINE 0 0 0
c2t5d0 ONLINE 0 0 0
c2t6d0 ONLINE 0 0 0
c2t7d0 ONLINE 0 0 0
For which list reports:
# zpool list backup
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
backup 13.5T 434K 13.5T 0% ONLINE -
Yet df and zfs list shows something else:
root at backup1:~# zfs list
NAME USED AVAIL REFER MOUNTPOINT
backup 262K 11.5T 1.78K none
backup/files 32.0K 11.5T 32.0K /export/files
...
# df -h
Filesystem size used avail capacity Mounted on
...
backup/files 11T 32K 11T 1% /export/files
Why does AVAIL differ for such a large amount?

See the man pages for zpool and zfs for a description of their meanings. -- richard> (NexentaOS_20080131) > >
