I did not get this email for some reason, Freddie. So, I am seeing it just now. zfs-fuse-0.6.9 is a different beast compared to 0.6.0. There are tonnes of fixes in zfs-fuse code and in zfs which are now part of 0.6.9. I think it may be worthwhile to invest a day and do the experiment again with 0.6.9. I have been very happy with dedup on my backup (which stores data from all my machines, and hence has lot of duplication). Dedup and compression combined saves me about 35% on my box (It is a i7 920 with 12GB RAM). In OS, I think there is a SMF tie up to handle the device removal/addition. The same is handled through a script in 0.6.9. A decent script which can handle hot spares comes with the install. You can of course change it to do whatever you want. -devsk -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

H Can you explain some of or link me to the bad design choices or H idiosyncrasies that make Ubuntu not stable as a server OS? H H I'm only refering to the Ubuntu Server LTS releases (5 year long term H support) which to date have included 6.06, 8.04, and 10.04. The LTS H releases are held to a higher standard (more showcase) than their other H releases (testing). Ubuntu uses non-LTS releases to encourage rapid H project development (e.g. adding GRUB2 in 9.10). I won't argue about H the non-LTS releases. E Specifically, even on the LTS releases, the server version actually E uses the same packages as the desktop version, which leads to problems E with assumed defaults. Classic case is iptables, where many of the E management packages that go with it use desktop-oriented defaults rather E than server-oriented defaults. So, when you upgrade (or, even just E update), it tends to break things. H I've seen stuff break on upgrades as well, although updates have been fine H for me. This breakage is why I delay upgrades on shared machines that H impact others (e.g. on HTPCs with MythTV on Ubuntu) until I know I can do H a clean slate rebuild if the upgrade doesn't go right, and often do the H clean slate rebuild anyway. I treat an Ubuntu upgrade similar to a H Windows upgrade (e.g. WinXP to Win7). E I've also seen issues with obsoleting/removing packages (or, more E likely, specific items from packages) without notification. I lost the E libstdc++5 library after 8.04 (it's not even in the 10.04 LTS), and E there was no mention of it being deleted, not even buried in release E notes. H Features lost to claims of 'UI design improvement and simplification' are H right up there on the annoyance list. Removed features often end up in H big discussion threads on http://brainstorm.ubuntu.com/ . This moving H target characteristic certainly makes it harder to get programs working H that aren't already in the repositories. At least an LTS release has a H safe 3 year usage window (as all LTS packages are maintained for 3 years, H and server packages are maintained for 5 years). E Ubuntu doesn't seem to really care about long-term stability. I'm not E talking about the kernel ABI (which, is really out of their hands). I'm E talking about being very careful about not breaking userland and E admin-land stuff without advanced notice, and significant failure to E support a transition period. Stuff just goes away and/or breaks at a E whim between releases. H Ubuntu's long term stability (i.e. software compatibility) appears H intended to stay within a single LTS version, which I feel is really H only 'for sure' for 3 years. That is on the short end of the range of H even popular general desktop OSes (WinXP is an outlier). H H In spite of its shortcoming, the primary advantages Ubuntu maintains are H 1.) wider, earlier hardware support H 2.) rapid iteration: a regular release cycle that gets software into H testing and use, in preparation for the next release cycle for that H software and Ubuntu as a whole H H I think Ubuntu LTS still makes sense for machines (even servers) that H don't need long-term stability (i.e. software compatibility) and can H benefit from the earlier hardware support it offers. It's not an OS to H install and leave alone (only patching) for extended time periods. E All of which is fine if you're running a home server, or maybe designing E a black-box device. None of which is acceptable for general-purpose, E server-room machines. H It is fine for virtual servers intended to run small/ephemeral H websites that you don't mind migrating again in the near term.

From: zfs-discuss-boun...@opensolaris.org [mailto:zfs-discuss- boun...@opensolaris.org] On Behalf Of Ben Miles What supporting applications are there on Ubuntu for RAIDZ? I see, supporting applications is just confusing English, because your filesystem isn't an application. I think you're just asking How can I do raid on ubuntu. This question might be more appropriate on an ubuntu list instead. But here's a quick answer anyway: You can do zfs-fuse. It's not as good as having ZFS included natively with your OS. Aside from that, there is no raidz available in ubuntu, or any linux. (Well, at least theoretically you could use the Lawrence Livermore National Laboratory linux port of ZFS, http://wiki.github.com/behlendorf/zfs/, which will allow you to create raidz zpool's and then you can format the zvol with ext3/ext4). But this is lacking a lot of functionality of zfs, and extremely new. If you don't need raidz for example, if raid5 is ok ... man pvcreate, man vgcreate, man lvcreate. It's not as good as zfs or raidz, but it does support software raid5. But why would you want to do software raid5 on anything that doesn't have zfs? If you're not using zfs, you should get a hardware raid controller with writeback cache and BBU. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

[zfs-discuss] ZFS on Ubuntu
How much of a difference is there in supporting applications in between Ubuntu and OpenSolaris? I was not considering Ubuntu until OpenSOlaris would not load onto my machine... Any info would be great. I have not been able to find any sort of comparison of ZFS on Ubuntu and OS. Thanks.

FreeBSD 8.1 includes ZFSv14 with patches available for ZFSv15 and ZFSv16. You'll get a more stable, better performant system than trying to shoehorn ZFS-FUSE into Ubuntu (we've tried with Debian, and ZFS-FUSE is good for short-term testing, but not production use). -- Freddie Cash fjwc...@gmail.com ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

See a previous thread on this list (i.e. look in the archives for May/June) for a still-in-progress port of kernel-level ZFS to Linux. It's not ready yet, but they promise Real Soon Now! That said, if you need ZFS right now, it's either FreeBSD or OpenSolaris (or Solaris 10). Two other considerations from your original message: (1) What do you mean by supporting applications? Do you mean are the same applications available on Linux and OpenSolaris? Or do you mean that you are writing an application (or have application source) that was targeted for OpenSolaris/Solaris, and would like to now port it to Linux? (2) Ubuntu is a desktop distribution. Don't be fooled by their server version. It's not - it has too many idiosyncrasies and bad design choices to be a stable server OS. Use something like Debian, SLES, or RHEL/CentOS. (also - have you tried installing the original 2009.06 stable OpenSolaris version? It might not have the install issues you're running into with the Dev branch, and give you something to do while you wait for the next 2010.X stable version of OpenSolaris...) -- Erik Trimble Java System Support Mailstop: usca22-123 Phone: x17195 Santa Clara, CA ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
