Over the weekend I got ZFS up and running under FreeBSD and have had much the same experience with it that I have with Solaris - it works great out of the box and once configured, it is easy to forget about. So far the only real difference is anything you might tune via /etc/system (or mdb) is done via sysctl.*
I have a server for internal use where we keep files for some months and then delete them. Usually we have some TB and I really wanted to use FreeBSD since it also run it as a mail-server and trouble-ticket-server. But ufs2 does not scale well especially if background-fsck is not possible after a unplanned restart. When zfs came along I was anxious to try it out. So I installed solaris on a test-server but managing apps on the solaris-server is a bit of a pain with my (FreeBSD) background. So last week I replaced the solaris-test-box with FreeBSD and zfs and is impressed with Pawel's great work :-)
And a big thanks to Pawel for making this available - its letting me use ZFS where I couldn't before!
Me too thank Pawel. Are there any tunables that I can look at to improve writes? The server is a 2-way dell pe 2850 at 2.8 GHz and 4 GB ram with HTT disabled and 2 qlogic 2300 hba's. I boot of internal scsi-disks and have attached a nexsan atabeast with 10 TB of storage where /usr/local and /home is located. Writes are usually approx. 20-30 MB/s (zpool iostat 1) and peak at 40-45 MB/s. I have recompiled the kernel without WITNESS. The nexsan has two raid-controllers where each controller has five LUN's. All 10 LUN's are in a raidz2 pool. Each LUN itself is four 400 GB disks in hardware raid-5. The nexsan can't do jbod. Being able to install apps using ports is a great relief. I can help test on my server if needed. regards Claus _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
