Static IP OpenSolaris
Setting a static IP in OpenSolaris is similar to Linux, but yet again; differences arise…
vi /etc/resolve.conf (make sure dns is correct [nameserver 10.0.0.1] vi /etc/nwam/llp [change 'gani0 dhcp' to 'gani0 static 10.0.0.100' where gani0 is your interface, and 10.0.0.100 is the ip address you would like to assign] # restart network vi /etc/defaultrouter (add your router '10.0.0.1') svcadm enable svc:/network/physical:default svcadm restart svc:/network/physical:nwam
This is a quickie but a goodie…

ZFS Dedup | OpenSolaris repos | beadm
DEDUP IS AMAZING. Can’t wait to try it out, but I’m waiting for my system to upgrade from the dev repository, err, I might just hold off cause it’s taking forever. Maybe I’ll play with it in a VM, instead of my Home NAS :*
Anywho please read up on it here: http://blogs.sun.com/bonwick/entry/zfs_dedupIt’s an amazing technology, and I’m super happy that it’s finally out.

Just in case you want to upgrade 111b to 127, or just have the most up to date packages try the following:
pkg set-publisher -O http://pkg.opensolaris.org/dev "opensolaris.dev" pkg set-publisher -P opensolaris.dev
Now when you look at your repos, dev is default or ‘preferred’
fsk141@TrayNAS:/mnt$ pkg publisher PUBLISHER TYPE STATUS URI opensolaris.dev (preferred) origin online http://pkg.opensolaris.org/dev/ opensolaris.org origin online http://pkg.opensolaris.org/release/

As I work with OpenSolaris I am continually amazed, and pissed off at the same time. Where some things are insanely simple and straightforward. Other things are tedious, and hard because of my Linux background. Another thing that I am letdown is the lack of community like Arch Linux. There is a very large OpenSolaris community, but not in the sense of packages, and a lot is left to you (as in manually compile)
——One of the difficult concepts to grasp is the boot environment concept. It’s kinda like a snapshot of sorts for your boot environment. Since OpenSolaris isn’t a rolling distro like Arch Linux, there are different revisions. Well instead of forcing some difficult reinstall you can simply ‘pkg image-update’ and upon your next reboot you have your new environment. You also have the ability to easily revert.

beadm is a great tool to modify your BE, and I love the simplicity in the BE scheme.

Speed up Open Solaris Boot (Fix Slow Boot)
It’s so annoying to wait 5+ minutes for Open Solaris to boot. Come to find out it’s because of the stupid graphical boot on startup. Damn gui’ness
1) Fix Grub menu.lst
- Edit /rpool/boot/grub/menu.lst
- Comment the following
splashimage foreground background
- Remove ‘console=graphics’ from the ‘kernel’ line
You should end up with something like this:
splashimage /boot/grub/splash.xpm.gz background 215ECA timeout 30 default 2 #---------- ADDED BY BOOTADM - DO NOT EDIT ---------- title OpenSolaris 2009.06 findroot (pool_rpool,0,a) bootfs rpool/ROOT/opensolaris #splashimage /boot/solaris.xpm #foreground d25f00 #background 115d93 #kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS,console=graphics kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS module$ /platform/i86pc/$ISADIR/boot_archive #---------------------END BOOTADM-------------------- title TrayNAS_Nov_21 findroot (pool_rpool,0,a) bootfs rpool/ROOT/TrayNAS_Nov_21 kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS module$ /platform/i86pc/$ISADIR/boot_archive #============ End of LIBBE entry ============= title opensolaris-1 findroot (pool_rpool,0,a) bootfs rpool/ROOT/opensolaris-1 #splashimage /boot/solaris.xpm #foreground d25f00 #background 115d93 #kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS,console=graphics kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS module$ /platform/i86pc/$ISADIR/boot_archive #============ End of LIBBE entry =============

ZFS Pool (Setup & Configure)
ZFS is the best option for a NAS system. It makes for a super simple home NAS, and does away with a lot of config hassles. This is due to the fact that a lot of core services are built into zfs, or into the zfs stack rather. To setup any “extra” of zfs, all you need is a one line zfs command. (zfs set sharenfs=on <pool> == instant nfs share)
1) Create the Pool
We need to fetch the disk ID’s (the number after the disk number)
format &lt;/dev/null
So if we run that command I can pull out (c8d0 c8d1 c9d0 c9d1) as shown below:
root@TrayNAS:~# format &lt;/dev/null Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c7d0 &lt;DEFAULT cyl 3904 alt 2 hd 128 sec 32&gt; /pci@0,0/pci-ide@1f,1/ide@0/cmdk@0,0 1. c8d0 &lt;DEFAULT cyl 60797 alt 2 hd 255 sec 252&gt; /pci@0,0/pci-ide@1f,2/ide@0/cmdk@0,0 2. c8d1 &lt;DEFAULT cyl 60798 alt 2 hd 255 sec 189&gt; /pci@0,0/pci-ide@1f,2/ide@0/cmdk@1,0 3. c9d0 &lt;DEFAULT cyl 60798 alt 2 hd 255 sec 189&gt; /pci@0,0/pci-ide@1f,2/ide@1/cmdk@0,0 4. c9d1 &lt;DEFAULT cyl 60798 alt 2 hd 255 sec 189&gt; /pci@0,0/pci-ide@1f,2/ide@1/cmdk@1,0 Specify disk (enter its number):
Take the extracted disk ID’s (c8d0 c8d1 c9d0 c9d1) and apply them to the next command. Edit accordingly depending on what pool type you would like. (mirror, raidz1, raidz2)
zpool create -f ambry raidz1 c8d0 c8d1 c9d0 c9d1
I had to use -f because I have 3x 1.5TB drives, and one 2TB drive…
Now that we have the pool created, lets marvel at what we accomplished:
root@TrayNAS:~# zpool list ambry NAME SIZE USED AVAIL CAP HEALTH ALTROOT ambry 5.44T 137K 5.44T 0% ONLINE - root@TrayNAS:~# zfs list ambry NAME USED AVAIL REFER MOUNTPOINT ambry 95.8K 4.00T 28.4K /ambry
The difference in size is just one of those little quirks (zpool == raw disks, zfs == real space)
Another check just to make sure were all good, and using raidz1 (1 parity disk)
root@TrayNAS:~# zpool status ambry pool: ambry state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM ambry ONLINE 0 0 0 raidz1 ONLINE 0 0 0 c8d0 ONLINE 0 0 0 c8d1 ONLINE 0 0 0 c9d0 ONLINE 0 0 0 c9d1 ONLINE 0 0 0 errors: No known data errors
Everything looks good, lets setup some filesystems, sharing, compression, and copy over our data…
For the rest of the write up, I’ll just output the commands I used to create my environment:
root@TrayNAS:~# zfs create ambry/Media root@TrayNAS:~# zfs create ambry/Downloads root@TrayNAS:~# zfs list | grep ambry ambry 176K 4.00T 31.4K /ambry ambry/Downloads 28.4K 4.00T 28.4K /ambry/Downloads ambry/Media 28.4K 4.00T 28.4K /ambry/Media root@TrayNAS:~# zfs get all ambry NAME PROPERTY VALUE SOURCE ambry type filesystem - ambry creation Sat Nov 21 12:48 2009 - ambry used 176K - ambry available 4.00T - ambry referenced 31.4K - ambry compressratio 1.00x - ambry mounted yes - ambry quota none default ambry reservation none default ambry recordsize 128K default ambry mountpoint /ambry default ambry sharenfs off default ambry checksum on default ambry compression off default ambry atime on default ambry devices on default ambry exec on default ambry setuid on default ambry readonly off default ambry zoned off default ambry snapdir hidden default ambry aclmode groupmask default ambry aclinherit restricted default ambry canmount on default ambry shareiscsi off default ambry xattr on default ambry copies 1 default ambry version 3 - ambry utf8only off - ambry normalization none - ambry casesensitivity sensitive - ambry vscan off default ambry nbmand off default ambry sharesmb off default ambry refquota none default ambry refreservation none default ambry primarycache all default ambry secondarycache all default ambry usedbysnapshots 0 - ambry usedbydataset 31.4K - ambry usedbychildren 144K - ambry usedbyrefreservation 0 -
I just created two filesystems to store my data, and then listed the zfs attributes available to me. I would like to take advantage of a few attributes, namely (compression, nfs, snapshots)
root@TrayNAS:~# zfs set sharenfs=rw,anon=0 ambry #allows root access from all hosts root@TrayNAS:/# zfs set compression=on ambry/Media root@TrayNAS:/# zfs set compression=on ambry/Downloads ^^^ I could set compression on for the whole ambry device, but want a little more fine grained control. ^^^ mkdir -p /old_ambry/Media mkdir /old_ambry/Downloads mount 10.0.0.100:/ambry/Media /old_ambry/Media mount 10.0.0.100:/ambry/Downloads /old_ambry/Downloads --- copied all my date over ---
I set compression on before moving data since it doesn’t activate recursively. Also I could have used zfs cloning, yet I have no need for my previous snapshots, so it’s not necessary…
More to come soon, but at this point you should be able to have a fully functioning NAS, with nfs. Enjoy

NTP Open Solaris (Setup & Configure)
NTP is awesome, it’s been around forever, and it’s one of the first things I setup on any new machine. This is an especially important service for a NAS device, since sync times are crucial, and there are many important services that are time dependent (snapshots for example).
1) Set the Time
ntpdate 0.pool.ntp.org
— Output —
root@TrayNAS:/etc/inet# ntpdate 0.pool.ntp.org 21 Nov 12:21:19 ntpdate[1296]: adjust time server 66.96.96.29 offset -0.000521 sec
2) Configure
cp /etc/inet/ntp.server /etc/inet/ntp.conf echo "server 0.pool.ntp.org\nserver 1.pool.ntp.org\nserver 2.pool.ntp.org" >> /etc/inet/ntp.conf svcadm enable ntp svcs ntp
— Output —
root@TrayNAS:/etc/inet# svcs ntp STATE STIME FMRI online 12:12:57 svc:/network/ntp:default
Woot, time is setup. Enjoy synchronized time…

Opensolaris blast on the way.
I was planning to put one giant post on how to setup a NAS with Open Solaris & NAS. Yet I think it would be nice to have a few key posts, and then group them together in the end. I just installed Open Solaris on my new machine. And am starting the setup… More to come soon.
