Debian Sarge
kernel-patch-vserver 1.9.5.3
util-vserver 0.30.204-5sarge
kernel-image-2.6.8+vserver_custom01_i386
drbd0.7-module-2.6.8+vserver_0.7.10-3+custom01_i386
Everything updated and recent from Debian stock.
Setting up a guest in the default /var/lib and /var/run worked nice.
DRBD alone works nice - as usual.
But I would like to have everything belonging to the guest on a
DRBD-device, to restart the guest in case of failover on the other node.
cel600:/# cat /etc/fstab | grep drbd
/dev/drbd0 /ha-vser42 ext3
rw,user,noauto,user_xattr,errors=remount-ro 0 1
First idea was to 'build' the guest directly into /ha-vser42
cel600:/# vserver -v vs27 build --force -m debootstrap --hostname
vs27.nack.at --netdev eth0 --interface 192.168.0.27/24 --context 27
sarge /ha-vser42 ftp://ftp.debian.org/debian
This does not work, and because of missing docs I could not find out
what the correct options and arguments should be, or if this is possible.
After some trial and error I did 'cp -a /etc/vservers' to /ha-vser42,
mkdir /ha-vser42/var/<bla>, exchanged /etc/vservers against a symbolic
link, changed the symbolic links in .defaults
cel600:/# ls -all /etc/vservers
lrwxrwxrwx 1 root root 23 2005-06-15 23:49 /etc/vservers ->
/ha-vser42/etc/vservers
cel600:/# ls -all /ha-vser42/etc/vservers/.defaults
total 16
drwxr-xr-x 4 root root 4096 2005-06-16 00:56 .
drwxr-xr-x 7 root root 4096 2005-06-16 01:56 ..
drwxr-xr-x 2 root root 4096 2005-05-24 22:22 apps
drwxr-xr-x 2 root root 4096 2005-05-24 22:22 files
lrwxrwxrwx 1 root root 31 2005-06-16 00:55 run.rev ->
/ha-vser42/var/run/vservers.rev
lrwxrwxrwx 1 root root 27 2005-06-16 00:56 vdirbase ->
/ha-vser42/var/lib/vservers
After removing all guests, I built new ones with the same method, which
worked nice before on the default configuration:
cel600:/# vserver -v vs27 build --force -m debootstrap --hostname
vs27.nack.at --netdev eth0 --interface 192.168.0.27/24 --context 27 --
-d sarge -m http://ftp.at.debian.org/debian/
This seemed to work nice, but is not startable:
cel600:/# vserver vs27 start
vcontext: execvp("/etc/init.d/rc"): Permission denied
Another trial:
cel600:/ha-vser42/etc/vservers/.defaults# vserver -v vs24 build --force
-m debootstrap --hostname vs24.nack.at --netdev eth0 --interface
192.168.0.27/24 --context 24 -- -d sarge -m http://ftp.at.debian.org/debian/

Hmm.
