SUN wants to sue back against NetApp

As you might have read in blogs or on newssites, NetApp sued SUN, as they are infringing patents of NetApp (at least, this is what NetApp is saying). Now NetApp pushed SUN to unfree the ZFS filesystem and to only sell it with some properitary storages. This is of course a big slap into the face of the open source community and against all users of ZFS (including the whole FreeBSD community, who ported ZFS to their OS).
Now Jonathan writes in this blog (as usual his blog entry has a sassy URL again
), that SUN is not going to agree with NetApps allowances and that they'll use their patents to defend and protect their innovations and the open source community. From my sight, a very nice move of SUN as it's good to know, that the open source community has a big player in their rows.I personally hope that this battle can be fought without lawsuits and that both sides can find a solution that it good for either.

Wow! Pretty neat tool! Just tried it and it's really cool. I know "screen" can act similar,

The SUN Solaris 10 Media Kit, which I ordered (for free) about one ago, arrived today. A nice DVD jewel case with 3 DVDs in it.- 1 x Solaris 10 11/06 SPARC architecture
- 1 x Solaris 10 11/06 x86/x64 architecture
- 1 x SUN Studio 11 / Java Studio / Net Beans
Pretty cool. Thanks a lot SUN! I'll find some good places to use these DVDs

I've done my first steps in SUN's Dtrace today and I have to admit that it is a very mighty tool. It took me less than 7 lines to create a "strace/truss" like example script (taken from the very good documentation). Very interessting stuff. When I've got some spare time, I think I'll have a closer look at the D-language and will lear working with Dtrace (I didn't get further than page 40 or so )ZFS and "Poor Man's Thumper"

Today I got two new hard discs for my local file server (thanks to my mate Tommy for the discs ). So I quickly mounted them into the case of my server and booted the box.As expected the discs were dected as well by the BIOS as by SunOS. So all I had to do, was adding them to my current ZFS data pool- which was done in less than two minutes.
Verify the OS detected the discs:

There we are... c1d1 and c2d1 are the new discs (currently w/o label, that's why the drive type is unknow)

In his blog, Joerg Moellenkamp points to an interessting Benchmark. ZFS vs. Veritas' VxFS. Have a look at it- it's worth reading.
ZFS as kinda "version control system"

Here Joerg Moellenkamp developed an idea for using ZFS as kind of "version control system" e. g. for a website. IMHO a pretty neat idea!ZFS compression and filesystem cache

Even if the data I used in this example isn't reasonable, the result is pretty impressive though:Creation of a 1 GiB file w/o zfs compression/filesystem cache:
QUOTE:
[root@exitus ~pgsql]# time mkfile 1g foo.1g
mkfile 1g foo.1g 0.07s user 7.81s system 8% cpu 1:27.90 total
mkfile 1g foo.1g 0.07s user 7.81s system 8% cpu 1:27.90 total
After doing a "zfs set compression=on data/postgresql":
QUOTE:
[root@exitus ~pgsql]# time mkfile 1g foo.1g
mkfile 1g foo.1g 0.07s user 7.27s system 58% cpu 12.632 total
mkfile 1g foo.1g 0.07s user 7.27s system 58% cpu 12.632 total
More CPU usage (by the filesystem cache) but the write operation was 6 times faster as it was performed in memory before the physical write operation has been performed.
Playing around with zfs

I am currently playing around with ZFS on my SunOS File Server. ZFS is a new developed file system (initially called: Zettabyte File System). ZFS is an easy to administer but mighty file system. Find the basic administration guide here.I just created a ZFS for my /data directory. It is pretty easy, as the zfs commands do everything needed by theirselfs. Just do s. th. like this to create a pool: "zpool create <name> mirror c1d0s5 c2d0s5" (I created the zfs on a slice, as I don't have two additional disks in that server to accomplish the recommended creation over a entire disk). And there you are. Zpool checks the disks, creates a filesystem and mounts the newly created file system. No I created a sub-filesystem for my user with a quota of 35GiB which is pretty simple as well. "zfs create <name>/doomy; zfs set quota=35G <name>/doomy" and you are ready to go. Impressive! I'm going to play around a bit more with it and will let you know about my experiences (if I'll get some

A SUN v20z delivered directly by SUN Microsystems wasn't able to detect this harddisc. Now! The six-four-dollar-question is: Why?

Linux, Raid-1, Cheetah, Geil!
Ich hab auf der SUN v20z gerade mal aus den zwei Platten ein RAID-1 gebaut. In der Kiste haengen zwei Seagate Cheetah 10K.6 (ST373307LC).
