Finally, justice is done.

Griffin PowerMate

Dug up the old PowerMate today. I had forgotten how much fun it was. Glad I didn’t throw it away.

The irony is not lost on me

On dealing with unresponsive/uncooperative vendors and consultants…

It’s like looking at my shower for three weeks because the plumber won’t return my calls. Yeah the plumber’s an asshole, but I’m the one who stinks.

Final Cut Pro X seriously makes me want to start editing again

The Sound of 1,700 Jaws Dropping – Larry’s Blog.

The new interface drew applause, 64-bit support and background rendering had people drooling and the new price of $299 received a standing ovation.

A bit of shameless self promotion

Setup NFS on Mac OS X 10.6

Couldn’t find a single good guide for doing this, so here it goes. It’s super simple (once you know the trick).

On the Server Mac:

Open Terminal:
sudo nfsd enable

This starts the nfs server and sets it to startup on reboot.

Edit /etc/exports (create if it does not exist)
Type the full path of the folder you want to share. In my case it was the USB drive attached to my MacMini but it could be any folder. Optional: Use the “-alldirs” option to allow clients to mount any directory under there.

If your UIDs across machines do not match the “-mapall” will map all IDs with an ID that has access to the directory. Find your ID by typing “id” at the terminal on the server. This may not be the most secure setup in the world, but it works and for my home use is perfectly acceptable. There are ways to restrict to a specific network or host.

Anyway, my /etc/exports looks like this.

/Volumes/storage1 -alldirs -mapall=501

Verify via a showmount -e

gallifrey:~ smcgrath$ showmount -e
Exports list on localhost:
/Volumes/storage1                   Everyone
gallifrey:~ smcgrath$

Your server is ready. On the client, create a directory to mount to (recommended somewhere in /Volumes) and mount the nfs export.

sudo mkdir /Volumes/storage1-nfs

sudo mount -o rsize=32768,wsize=32768,intr,noatime -t nfs gallifrey.local:/Volumes/storage1 /Volumes/storage1-nfs

Obvious replace with:
host:/full/path/to/export /path/to/local/mountpoint

Done.

ZFS Dedup Available – Revised

With the holidays and all, I missed the release of OpenSolaris build snv_128 which (finally) includes zfs dedup. So it’s time to catch up. I fired up my snv_126 VirtualBox Machine,

sean@neptune2:~$ uname -a

SunOS neptune2 5.11 snv_126 i86pc i386 i86pc Solaris

sean@neptune2:~$

and performed the image update.

pfexec pkg image-update –be-name b128a

After Install, Update, reboot…

sean@neptune2:~$ uname -a

SunOS neptune2 5.11 snv_130 i86pc i386 i86pc Solaris

sean@neptune2:~$ 

We’re up to snv_130

And there is a new version of zfs available

sean@neptune2:~$ zpool upgrade

This system is currently running ZFS pool version 22.

The following pools are out of date, and can be upgraded.  After being

upgraded, these pools will no longer be accessible by older software versions.

VER  POOL

—  ————

19   rpool

19   tank

Use ‘zpool upgrade -v’ for a list of available versions and their associated

features.

sean@neptune2:~$ 

sean@neptune2:~$ pfexec zpool upgrade rpool

This system is currently running ZFS pool version 22.

Successfully upgraded ‘rpool’ from version 19 to version 22

sean@neptune2:~$ pfexec zpool upgrade tank

This system is currently running ZFS pool version 22.

Successfully upgraded ‘tank’ from version 19 to version 22

sean@neptune2:~$ 

And dedup is now an option

sean@neptune2:~$ zfs get dedup rpool

NAME   PROPERTY  VALUE          SOURCE

rpool  dedup     off            default

sean@neptune2:~$ 

Now we turn on dedup or our boot volume and our “tank” pool

sean@neptune2:~$ pfexec zfs set dedup=sha256,verify rpool

sean@neptune2:~$ pfexec zfs set dedup=sha256,verify tank

and turn in off on our “swap” and “dump” file systems

sean@neptune2:~$ pfexec zfs set dedup=off rpool/swap

sean@neptune2:~$ pfexec zfs set dedup=off rpool/dump

Let’s look at the free space on tank

tank                                  5.37G  4.46G  1.19G  /tank

We copy an ISO that’s about 1 GB

sean@neptune2:~$ ls -lah /tank/sean

total 1.2G

drwxr-xr-x 2 sean root     3 2010-01-17 15:00 .

drwxr-xr-x 5 root root     5 2010-01-17 14:59 ..

-rw-r–r– 1 sean staff 1.2G 2010-01-17 11:34 ARCHIVE-011710.iso

We see tank’s available size has decreased accordingly

tank                                  5.37G  4.46G  1.19G  /tank

We copy the file

sean@neptune2:~$ cp /tank/sean/ARCHIVE-011710.iso  /tank/sean/ARCHIVE-011710-dupe.iso

Now we have 2 1.2 GB files

sean@neptune2:~$ ls -lah /tank/seantotal 2.4G

drwxr-xr-x 2 sean root     4 2010-01-17 16:31 .

drwxr-xr-x 5 root root     5 2010-01-17 14:59 ..

-rw-r–r– 1 sean staff 1.2G 2010-01-17 16:32 ARCHIVE-011710-dupe.iso

-rw-r–r– 1 sean staff 1.2G 2010-01-17 11:34 ARCHIVE-011710.iso

But the free space has not gone down in “zfs list”, although interestingly the total size went up.

Filesystem            Size  Used Avail Use% Mounted on

tank                  6.56G  4.44G  2.38G  /tank

For laughs let’s copy it a third time

and we have three 1.2 GB files

sean@neptune2:~$ ls -lah /tank/sean

total 3.6G

drwxr-xr-x 2 sean root     5 2010-01-17 16:43 .

drwxr-xr-x 5 root root     5 2010-01-17 14:59 ..

-rw-r–r– 1 sean staff 1.2G 2010-01-17 16:32 ARCHIVE-011710-dupe.iso

-rw-r–r– 1 sean staff 1.2G 2010-01-17 16:44 ARCHIVE-011710-dupe2.iso

-rw-r–r– 1 sean staff 1.2G 2010-01-17 11:34 ARCHIVE-011710.iso

Free space is about the same:

sean@neptune2:~$ zfs list | grep tank

tank                                  7.75G  4.42G  3.57G  /tank

tank/files                              21K  4.42G    21K  /tank/files

tank/iscsiluns                        4.00G  4.42G  4.00G  /tank/iscsiluns

tank/svnzone1_ds                       157M  4.42G    21K  /zfs

tank/svnzone1_ds/svn                   157M  4.42G   157M  /svn

tank/zone1_ds                         23.5M  4.42G    21K  /tank/zone1_ds
