Federico Biancuzzi interviewed the developers to discuss all the details of FreeBSD 7.0: networking and SMP performance, SCTP support, the new IPSEC stack, virtualization, monitoring frameworks, ports, storage limits and a new journaling facility, what changed in the accounting file format, jemalloc(), ULE, and more."

      Me too. I was excited when I saw they had i386 drivers on FreeBSD (and I had been using the linux x64 ones for a while) but was more than slightly annoyed that they didn't have x64 FreeBSD drivers.

      Really, if you can do one, why is the other so much more trouble that you would ignore it?

          Thanks for the info. While I don't have the abilities to do any of this, or the resources to "encourage" someone else to, it is nice to know that the problems preventing better i386 and any amd64 use are being worked on.

      I was toying around with Freebsd 7.0 RC3 just a few days ago, well actually I was testing it to see if ZFS was really working as claimed. A very basic installation to a 40gb disk went pretty quick (5 to 10 minutes). Rebooted into the installed system and everything was fine. Took an old 1.6gb drive I had and plugged it right in, recognized as /dev/da1 or whatever. Ran "zpool create tank da1" and BAM! /tank already mounted and ready to go. No stupid fdisk, no stupid format command, no fstab nonsense.

      Now I wouldn't run out and switch everything to freebsd 7 and zfs because work isn't finished. For example there's no ACL support since ZFS supports NFSv4 ACLs while freebsd only supports Posix1e. My next test will involve getting samba working and this may be a little tricky since there are some reports of issues with running samba on ZFS. But all of the available reports are quite old (half a year or older). I don't really care about the ACLs because I just intend to use the system as a single user and a convenient area to dump my files on a bunch of disks that all conveniently appear as one along with some redundancy (better than just a bunch of disks and raid5).

      • by nbritton (823086)
        Yes, but does ZFS RAID-Z2 work yet? The last time I tried it (FreeBSD 7-RC1) I got a kernel panic right off the bat. The test system was a 16 disk array using two Supermicro AOC-SAT2-MV8 cards (Marvell Hercules-2 PCI-X chipset). This same system worked perfectly fine using Solaris Express 10/07.
        • by Fweeky (41046)
          Using Broadcom ServerWorks motherboard chipset? Some pretty serious DMA bugs in the HT1000 were worked around pretty recently, not sure if they made it to RC1. There were also reports of problems with the Marvell SATA chipset used on that card, though mine works fine for what little use I have of it.
        • by Daniel_E (75554)
          raidz2 is working just fine on a 10 disk array I set up a few months ago.
      • I can tell you from first-hand experience that whatever the samba issues were, they've since been fixed. I've run ZFS with Samba as my home fileserver with 7.0RC1 and had no issues.
    • I switched from Gentoo Linux on my server to FreeBSD solely for ZFS.

      Yes, I'm running FreeBSD on a SPARC for ZFS. Not Solaris. LONG story; nothing against Solaris.

      You probably would, if you liked it, if not for any other reason. For most use cases, wether The Right Tool for The Job(tm) is Linux, BSD, Solaris or just about anything else should be determined by asking the people due to be in charge what they feel most comfortable with. And that's it. If you don't expect to push the system to its limits in a very specific way, fear a particular kind of attack vectors or require in-kernel support for this or that newfangled widget, be it hardware or software, and don't consider some platform a burden in the case of staff turnover, the most sensible choice is really what the staff would like to work with.

      Actually, in most other cases it's even easier, because there often is an industry standard - e.g. half (warning: that's an educated guess, that is, a number pulled out of my, er, back pocket, representing something close to reality in a simplified, but suitable way) of the banks and other financial institutions tend to use Solaris a lot (the other half using IBM stuff) just because a tried way of doing things for them and there's no point in changing that.

      And if you want an OS for personal use, feel free to choose on any basis you like, from the license to the number of lines of code to the project founder's hair color - just be careful not to become a brainwashed zealot...

      This is going to sound snarky, but it's not intended that way- if you don't already know the answer to that, you probably aren't going to choose FreeBSD.

        Just a little curious as to why you're still using pkg_add instead of portupgrade?

        For example, your "two commands" could just be one command, `portupgrade -R gnome2`, after which it'll figure out what else needs to be installed that you don't have and take care of it all.

        Do you use cvsup or cvsup-without-gui [slashdot.org]? I'd hope so....

          Or rather, `portinstall -R gnome2` for a new installation. You'd have to add a -N to the portupgrade command if you wanted it to install if it doesn't exist already. Of course, the two progams are actually the exact same program, sharing a man page.

I'm speaking here of FreeNAS [freenas.org] and pfSense [pfsense.com]. Both are designed to be embedded and run on FreeBSD, and both were designed to do very specific tasks. Both will install entirely on and boot directly from any garden variety USB flash drive. Because the memory footprint is so small, they run by loading the entire OS into a RAMdri

      According to the Guest OS compatibility table, FreeBSD 6.2 is supported on VMWare Workstation 6.0.2 and VMWare ACE 2.0.2

      Having said that, VMWare guest is running on a fairly standard sort of virtualised platform. With VMWare ESX 3.5 you can use a Buslogic virtual scsi controller or an LSI virtual scsi controller. So you may have to do some fiddling to get FreeBSD to load the appropriate device driver (don't ask me how, I've only ever done generic installs of FreeBSD)

      VMWare ESX Server 3.5 will (officially) support:
        * Ubuntu Linux 7.04
        * Solaris 10 for x86
        * Suze Linux Enterprise Server 10
        * Redhat Enterprise Linux 5
      and various other OSs...
