hi,
In my server i set up echo "set zfs:zfs_arc_max = 104857600" >> /etc/system ->100mb.
i rebooted and dd if=/dev/zero of=/y/y bs=1024 count=1000000000000
then
mdb -k

Kernel 61675 240 12%
ZFS File Data 86755 338 17%
Why ZFS File Data is not limited up to 100mb?
kstat -p zfs|grep size
zfs:0:arcstats:size 104839320 ->99m
why zfs file data from mdb is different from zfs:0:arcstatL:size?
which one show the correct zfs arc buffer?
