I have read the FAQ, and it states that encrypted data can''t be compressed. But is there any point in using compression on my media file server, that will store ripped DVD''s (which are compressed in their default state), our digital photos (JPEG - also compressed) and HD files (mostly .ts (transport stream) - also a form of compressionI). In other words can ZFS compress compressed files? Or should I just forget about having compression enabled? Mastiff - CEO of The Cinema Inferno This message posted from opensolaris.org

In other words can ZFS compress compressed files? Or should I just forget about having compression enabled?I would not use ZFS compression on filesystems intended to store already-compressed data such as images, mp3s, most video formats, etc. That is akin to zipping a .zip file, and will only waste cpu and memory, considering the compression in those formats will at least be on par with LZH if not better. -- Eric Enright
Thanks for the quick answer! That''s exactly what I suspected. Btw I''m looking around for hardware demands on this system, and I have problems finding anything. I was thinking about using an AMD XP2600 on a VIA KT-4 mobo wich has a few S-ATA ports, three IDE connections and an extra IDE card. Hard drives connected to them are all visible from the BIOS. Does that mean that I can use them with OpenSolaris as well, or isn''t it that simple? And is this system to anorectic for OpenSolaris which will mainly be accessed as a network media server from one computer at the time (either the HTPC or the bedroom computer) with the most demanding task being serving one ripped BluRay/HD-DVD at a time this way?

For a long time I used an AMD XP 2500+ as my "main" home machine, and it was just fine. I don''t believe you mentioned how much RAM you have. I had 1GB in that system, but 512 should be ok for light, streaming usage. My biggest concerns with your system would be the add-in IDE card not being supported, and/or the SATA chipset not being supported. I have little experience with SATA on Solaris, and have only ever used the SiiG 3114. From what I''ve read here YMMV... Quick answer though is to download CD1 of the latest release, boot to a shell, and take a look. -- Eric Enright

I just build a system with Gigabyte GA-M59SLI-S5 and 6 SATA2 drives. One system Seagate ES 250Gb disk, 5 Seagate ES 500Gb disks. 2.2Tb with raidz. Seems to work well with Nexenta. I could have put 5 ES 750Gb drives instead and had another TB. All in a midi-tower with an Athlon 3800+. This motherboard could probably handle another couple drives as well, although I''d probably get a full tower for that to deal with the heat. My laptop is actually loud that this system as well. I''d avoid IDE as even rounded cables are very fat. Nicholas -------------- next part -------------- An HTML attachment was scrubbed...

I assume Opensolaris will work since it is based on that. I couldn''t tell you if NCQ works, as Solaris is pretty new to me. If you give me some sort of cat /proc or dmesg | grep string I can send you the details. Nicholas -------------- next part -------------- An HTML attachment was scrubbed...

Attached. Had to install xserver-xorg-core, but thanks to apt it was relatively easy.

Note also I have the BIOS set to AHCI mode for the SATA controllers, not IDE. Nicholas -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://mail.opensolaris.org/pipermail/zfs-discuss/attachments/20070225/e7f22da8/attachment.html>

Although in IDE mode for the disk. Picked up everything. Now I''m having a iscsi target issue. Bad xml. Might be a Nexenta bug.

[zfs-discuss] Are media files compressable with ZFS?

Not all data can be compressed by a given algorithm. Turning on compression for some ZFS filesystem and then writing pre-compresed or encrypted data to that filesystem will only waste CPU cycles though -- ZFS will try to compress the data, fail to get a good enough compression ratio, and then store the data without compression.

Dang, I think I''m dead as far as Solaris goes. I checked the HCL and the Java compatibility check, and none of the two controllers I would need to use, one PCI IDE and one S-ATA on the KT-4 motherboard, will work with OpenSolaris. Annoying as heck, but it looks like I''m gonna have to stick with Windows. :-( Tor This message posted from opensolaris.org

Check it out: http://www.wizy.org/wiki/ZFS_on_FUSE The latest trunk version is already pretty good regarding stability, not so good regarding performance at the moment.
