Re: /tmp sticky bit differences on FreeBSD 8
2009/9/16 Matthew Seaman m.sea...@infracaninophile.co.uk: On FreeBSD 6,7 files are created with wheel group, but on 8 - with `gid`. It seems that ZFS uses SysV group semantics (new files get the 1ary group of the user unless the directory is set to SGID). UFS filesystems on 8.x still behave in the expected BSD way (new files get the same group as the directory unless the user is not a member of that group, when they get the users' 1ary group). There's a thread 'ZFS Group ownership' on this topic in freebsd-hack...@... at the moment. hmm, I use ZFS on FreeBSD 7, but still get wheel group and not egid. -- Artis Caune Everything should be made as simple as possible, but not simpler. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: Boot from RAIDZ in 8.0-BETA3?
2009/9/1 Jason Garrett kinged...@gmail.com: IMHO, unless you have a NEED to do this with the 8-BETA's I would not attempt. While I had this working in 8.0-BETA1 upon reboot I would loose data from entire mountpoints on the root pool. First it was /usr/ports, not a big deal. Then it was /var/db/pkg.. the system had no idea what was installed and what wasn't. This was a test machine, so no harm, no foul. I would definatley not recommend this AT ALL. Maybe you just messed with wrong zfs option or in wrong order and your mountpoints are not lost, but not-mounted or over-mounted? It's a little bit tricky to get zfs-root working, some things can go wrong if installation is not automated. -- Artis Caune Everything should be made as simple as possible, but not simpler. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

shell power in rc.conf
Hi,
Is there any reason of not using shell variables in rc.conf?
I want to tune rc.conf for easy editing and administration. Take for
example jail_list or cloned_interfaces with 10+ entries:
# interfaces
cloned_interfaces=carp1 bce0.10 carp10 bce0.20 carp20
ifconfig_bce0_10=10.0.0.1/24
ifconfig_bce0_20=10.0.1.1/24
ifconfig_bce0_20_alias0=10.0.1.2/32
ifconfig_carp10=vhid 10 advskew 100 pass MySecret 10.0.0.100/32
ifconfig_carp20=vhid 20 advskew 15 pass MySecret 10.0.1.100/32
# jails
jail_list=ns mail
jail_ns_hostname=ns
jail_ns_ip=10.10.10.1
jail_mail_hostname=mail
jail_mail_ip=10.10.10.2
Instead I can rewrite this to:
# interfaces
cloned_interfaces=${cloned_interfaces} bce0.10
ifconfig_bce0_10=10.0.0.1/24
cloned_interfaces=${cloned_interfaces} bce0.20
ifconfig_bce0_20=10.0.1.1/24
ifconfig_bce0_20_alias0=10.0.1.2/32
cloned_interfaces=${cloned_interfaces} carp10
ifconfig_carp10=vhid 10 advskew 100 pass MySecret 10.0.0.100/32
cloned_interfaces=${cloned_interfaces} carp20
ifconfig_carp20=vhid 20 advskew 15 pass MySecret 10.0.1.100/32
# jails
jail_list=${jail_list} ns
jail_ns_hostname=ns
jail_ns_ip=10.10.10.1
jail_list=${jail_list} mail
jail_mail_hostname=mail
jail_mail_ip=10.10.10.2
Now I can just comment out unused interface or jail, and it won't start up.

Re: fixit console with sshd
2009/4/28 n j nin...@gmail.com:
I was just wondering if someone could give me a quick advice on how
(or at least confirm it's possible) to start sshd in fixit console
i.e. how to boot FreeBSD off the CD1 (6.4-RELEASE) and enable SSH
access to it.
I believe booting off a live CD and restoring a backup over network
should be a relatively common recovery scenario, but googling around
produced no usable results other than get FreeSBIE live cd.
or you can build your own live cd:
# BUILDDIR=/home/my_live_cd
# mkdir $BUILDDIR
# cd /usr/src
# make buildworld
# make buildkernel
# make installworld DESTDIR=$BUILDDIR
# make distribution DESTDIR=$BUILDDIR
# make installkernel DESTDIR=$BUILDDIR
echo '/dev/acd0 / cd9660 ro 0 0' $BUILDDIR/etc/fstab
echo 'init_script=/etc/rc.my' $BUILDDIR/boot/loader.conf
echo exec /bin/sh $BUILDDIR/etc/rc.my
# you probably should script /etc/rc.my and
# mount rw memory fs over /var, /tmp, and others
# add useful packages
mount -t devfs devfs $BUILDDIR/dev
for pkg in apg-2.3.0b_1 bonnie++-1.93.04 stress-1.0.0; do
cp /home/pkgs/${pkg}.tbz $BUILDDIR/
chroot $BUILDDIR pkg_add /${pkg}.tbz
rm $BUILDDIR/${pkg}.tbz
done
umount $BUILDDIR/dev
# generate ssh keys
chroot $BUILDDIR /etc/rc.d/sshd keygen
# mkisofs -quiet -b boot/cdboot -no-emul-boot -r -iso-level 4 -V my
live cd -o /home/my_live_cd.iso $BUILDDIR
# burncd -v -s max data /home/my_live_cd.iso fixate
You can even read some new manpages while fixing servers :)

Re: Anyone runs 7.1 with an IBM X3650 (64 bits ARCH) ?
2009/3/13 Frank Bonnet f.bon...@esiee.fr: Hello Everything is in the subject :-) Thanks for any infos Purpose is migration of a mailhub We have some weird problems with sata disks, sas works just great. (ServeRAID 8k) 3Gbps not working, we get lot of aac cmd timeouts. IBM support cooked new firmwares, no help, raid bios is now loading 3-4 minutes, finaly they told to switch to 1.5Gbps. Works better, but anyway, we have replaced 2 disks in last 6 months and now one is waiting for replacement because of: aacd0: hard error cmd=write fsbn 455142322 btw, linux is freezing on ours x3650+sata (even their supported red hat or whatever it was) :) IBM support have also replaced IBM sata disks to non-IBM sata disks for 15 x3550 boxes, works fine. Before sata, we have only sas disks, no problems, ever. -- regards, Artis Caune .

ZFS on root with atime=off
Hi everyone, I install ZFS on root just like in Andrew ZFSOnRoot wiki page. I don't use legacy mount points. I also set atime=off on tank and all partitions inherit it from tank. When I reboot after install, root file system is mounted with atime option: # zfs get atime tank NAME PROPERTY VALUE SOURCE tank atime on temporary I can fix this with creating entry in fstab for root fs with noatime, but maybe there is some way how to pass options to vfs.root.mountfrom? -- regards, Artis Caune .
