Re: FreeBSD + ZFS on a production server?
Thank you all for discussing this with me. I really like to here your opinions. I wont answer to all of your posts, because half of them is off-topic, but still interesting to read. I haven't heard/read about any huge CPU consumptions from ZFS, not yet at least. If you have links to benchmarks and comparisons with other fses (UFS2 in particular) it would be grate! For the memory I've read that ZFS use up to approximately 700MB of ram for caching, which is quite much, but not too much compared to my 4GB that is available. However there doesn't seem to be an upper limit for ZFS, which I think is very bad. 2008/6/8 Wojciech Puchar [EMAIL PROTECTED]: The choice is probably between Debian 4.0r3, FreeBSD 7.0 and OpenSolaris 2008.05. All of them have their pros and cons. could you tell any pros for opensolaris? OpenSolaris 2008.05 didn't boot on my hardware, so it's out of this project anyway. The live-cd hangs on device detect. One of the pros for OpenSolaris I've noticed is the support for a virtual host and at the same time able to use ZFS, but that doesn't matter anymore because I can not boot it and ZFS will probably eat my memory if I can set an upper limit. I think Debian / Linux, almost falls off because it lacks support for native ZFS and I have not found any alternative filesystem that offer checksums on the fly. agree I have now found a filesystem for linux that do checksum on the fly, btrfs. But it is still very experimental, so I wont try it for this project. http://btrfs.wiki.kernel.org/ // Anders ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

That's good to know, thanks! Do you have any reference/link that describes how to manage that? It's good to know for the future. I always run my server on amd64-software, as far as I can, because I see better performance and I do not have the trouble with 4GB memory limit.

FreeBSD + ZFS on a production server?
Hello list! I plan to install a web server for production use and ZFS looks very interesting, especially since it has built-in support for RAID and checksum. The hardware is already purchased, a 1U-casis with a PhemonX4 9550 CPU, 4GB ECC RAM @ 800MHz and 2x500GB SATA disks and I am about to select the operating system to use. The choice is probably between Debian 4.0r3, FreeBSD 7.0 and OpenSolaris 2008.05. All of them have their pros and cons. I think Debian / Linux, almost falls off because it lacks support for native ZFS and I have not found any alternative filesystem that offer checksums on the fly. My main question is: How is the support for ZFS on FreeBSD? Is it sufficiently stable and fast enough to be used in production yet? If not, is there any alternative filesystem that offers checksums on the fly or other similar technology to reduce the risk of a corrupt filesystem that at the same time plays well with software RAID (RAID-1 in particular)?

Re: FreeBSD + ZFS on a production server?
Thanks for the quick answers! 2008/6/8 Fabian Keil [EMAIL PROTECTED]: Just in case you assume that ZFS on OpenSolaris 2008.05 would be superior to ZFS on FreeBSD, this hasn't been my experience. Yes, I assumed that because Sun can implement and optimize ZFS to fit OpenSolaris, while we run the risk with FreeBSD to implement bugs while we implement ZFS. 2008/6/8 Dick Hoogendijk [EMAIL PROTECTED]: The best stable (production) server with ZFS is solaris-10u5 If you want to boot off ZFS, S10u6 will support that. But these versions too need lots of ram. I think fbsd has a lighter footprint. As you might have read, I have quite a lot of RAM available on this server (4GB), but ofcource I want the operating system to take as little as possible so that I have as much RAM as possible over for the server processes to work with (mostly web-server and mysql-server). According to a page I have found it says that some basic (FreeBSD-specific) functions are not ready, how does that affect ZFS in general? http://wiki.freebsd.org/ZFS Regards Anders ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
