Believe all of them. They are only telling you what they know. The problem might just be how to interpret what they say :-) The man page for zfs says, For volumes, specifies the logical size of the volume. By default, creating a volume establishes a reservation of equal size. For storage pools with a version number of 9 or higher, a refreservation is set instead. Any changes to volsize are reflected in an equivalent change to the reservation (or refreservation). The volsize can only be set to a multiple of volblocksize, and cannot be zero. The reservation is kept equal to the volume's logical size to prevent unexpected behavior for consumers. Without the reservation, the volume could run out of space, resulting in undefined behavior or data corrup- tion, depending on how the volume is used. These effects can also occur when the volume size is changed while it is in use (particularly when shrinking the size). Extreme care should be used when adjusting the volume size. So you can expect that the zfs or zpool commands will take into account this space as being used/reserved. OTOH, the swap -l command will show the actual use of the device at the present time. -- richard > Justin > > # df -hk > > Filesystem size used avail capacity Mounted on > > /dev/dsk/c3t0d0s1 14G 4.0G 10G 28% / > > /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 6.4G 684K 6.4G 1% /etc/svc/volatile > > objfs 0K 0K 0K 0% /system/object > > /usr/lib/libc/libc_hwcap2.so.1 > > 14G 4.0G 10G 28% /lib/libc.so.1 > > fd 0K 0K 0K 0% /dev/fd > > swap 6.4G 28K 6.4G 1% /tmp > > swap 6.4G 24K 6.4G 1% /var/run > > swap 9.8G 24K 236M 1% /swap > > # swap -l > > swapfile dev swaplo blocks free > > /dev/zvol/dsk/swap/vol 181,1 8 19922936 19687704 > > # zfs list > > NAME USED AVAIL REFER MOUNTPOINT > > swap 9.61G 236M 24.5K /swap > > swap/vol 9.61G 236M 9.61G - > > # zpool list > > NAME SIZE USED AVAIL CAP HEALTH ALTROOT > > swap 20G 19.2G 791M 96% ONLINE - > > ------------------------------------------------------------------------ > > _______________________________________________ > zfs-discuss mailing list > zfs-discuss@opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss > _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
