SmartOS Command Line Tips
This topic contains helpful commands with examples of each command that will help you manage SmartOS. These tips were derived from a blog post by community member Mark Slatem. You can follow Mark and his adventures with the Illumos family of technology at:
Disk¶
These commands are specifically related to disks and ZFS pools.

Checking the status of usable space on a ZFS volume¶
zfs list zones
[root@smartosn2 ~]# zfs list zones
NAME USED AVAIL REFER MOUNTPOINT
zones 60.9G 485G 518K /zones
Turning on ZFS compression for an entire SmartOS system and confirm its enabled¶
zfs set compression=on zones && zfs get compression zones
[root@smartosn2 ~]# zfs set compression=on zones && zfs get compression
zones
NAME PROPERTY VALUE SOURCE
zones compression on local
Checking the status of the data compression ratio for zones¶
zfs get compressratio zones
[root@smartosn2 ~]# zfs get compressratio zones
NAME PROPERTY VALUE SOURCE
zones compressratio 1.46x -
Checking the current ZFS ARC size¶
kstat -p zfs:0:arcstats:size | cut -f2
[root@smartosn2 ~]# kstat -p zfs:0:arcstats:size | cut -f2

Networking¶
These commands are specifically related to statistics about networking.
Seeing the status of Network interfaces¶
dladm show-phys
[root@smartos-node-1 ~]# dladm show-phys
LINK MEDIA STATE SPEED DUPLEX DEVICE
igb0 Ethernet up 1000 full igb0
igb1 Ethernet unknown 0 half igb1
Seeing the MAC addresses for Network interfaces¶
dladm show-phys -m
[root@smartos-node-1 ~]# dladm show-phys -m
LINK SLOT ADDRESS INUSE CLIENT
igb0 primary 0:1e:67:1d:58:38 yes igb0
