Yes. It is true that ZFS redefines the meaning of available space. But most people like compression, snapshots, clones, and the pooling concept. It may just be that you want zfs list instead, df is old-school :-) OTOH, df does have a notion of file system specific options. It might be useful to have a df_zfs option which would effectively show the zfs list-like data. BTW, airlines also overprovision seats, which is why you might sometimes get bumped. Hotels do this as well. -- richard > [EMAIL PROTECTED] # df -h > Filesystem size used avail capacity Mounted on > /dev/dsk/c5t0d0s0 454G 12G 437G 3% / > /devices 0K 0K 0K 0% /devices > ctfs 0K 0K 0K 0% /system/contract > proc 0K 0K 0K 0% /proc > mnttab 0K 0K 0K 0% /etc/mnttab > swap 8.4G 876K 8.4G 1% /etc/svc/volatile > objfs 0K 0K 0K 0% /system/object > /usr/lib/libc/libc_hwcap2.so.1 > 454G 12G 437G 3% /lib/libc.so.1 > fd 0K 0K 0K 0% /dev/fd > swap 8.4G 40K 8.4G 1% /tmp > swap 8.4G 24K 8.4G 1% /var/run > /dev/dsk/c5t0d0s5 3.9G 1.8G 2.1G 46% /var/crash2 > log-pool 457G 120M 447G 1% /log-pool > thumper-pool/n01_oraadmin1 > 16T 1.4G 13T 1% /n01/oraadmin1 > thumper-pool/n01_oraarch1 > 16T 159M 13T 1% /n01/oraarch1 > thumper-pool/n01_oradata1 > 16T 98G 13T 1% /n01/oradata1 > thumper-pool/tst08a_ctl1 > 16T 17M 13T 1% /s01/controlfile1 > thumper-pool/tst08a_ctl2 > 16T 17M 13T 1% /s01/controlfile2 > thumper-pool/tst08a_ctl3 > 16T 17M 13T 1% /s01/controlfile3 > thumper-pool/tst32a_data > 16T 135G 13T 1% /s01/oradata1/tst32 > thumper-pool 16T 1.1T 13T 8% /thumper-pool > thumper-pool/home 16T 45K 13T 1% /thumper-pool/home > thumper-pool/home/db2inst1 > 16T 163G 13T 2% > /thumper-pool/home/db2inst1 > thumper-pool/home/kurt > 16T 223K 13T 1% /thumper-pool/home/kurt > thumper-pool/home/mahadev > 16T 40K 13T 1% > /thumper-pool/home/mahadev > thumper-pool/mrd-data > 16T 75G 13T 1% /thumper-pool/mrd-data > thumper-pool/software > 16T 6.3G 13T 1% /thumper-pool/software > thumper-pool/u01 16T 5.2G 13T 1% /u01 > thumper-pool/tst08a_data > 16T 761G 13T 6% /s01/oradata1/tst08 > log-pool/swim 50G 24K 50G 1% /log-pool/swim > log-pool/butterfinger > 457G 24K 457G 1% /log-pool/butterfinger > > _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
