Monitoring ZVOLs?

[dbi]

Is it possible to monitor the i/o stats of a ZFS volume (zfs create -V ...)?

$ zpool iostat

Nope. This will show the i/o stats for the whole pool or for the block devices of which it consists (-v). I need to monitor a particular zfs volume (or dataset).

zfs create -V 500G zfspool/zfsvolume01

export zfsvolume01 via iSCSI and monitor its I/O.
