I used wget and dragged some of the files over into a local directory and then modified Apache's DocumentRoot... restarted apache... and no problem at all.
I switch it back, and problems.
The same configuration did not give me a problem with the stable OpenVZ kernel.
Another question... sorta related but not.
Ok, in /etc/sysconfig/vz-scripts I have 101.mount and 101.umount and both are 755.
Check out the following behavior:
(before starting 101 - physical host)
[root@hprack6 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/cciss/c0d0p1 30G 1.8G 27G 7% /
none 1012M 0 1012M 0% /dev/shm
esus:/students 145G 31G 107G 23% /mnt/nfs/esus/students
esus:/home 145G 112G 26G 82% /mnt/nfs/esus/home
esus:/www/htdocs 55G 11G 43G 20% /mnt/nfs/esus/www
[root@hprack6 ~]#
(after starting vps - physical host)
[root@hprack6 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/cciss/c0d0p1 30G 1.8G 27G 7% /
none 1012M 0 1012M 0% /dev/shm
esus:/students 145G 31G 107G 23% /mnt/nfs/esus/students
esus:/home 145G 112G 26G 82% /mnt/nfs/esus/home
esus:/www/htdocs 55G 11G 43G 20% /mnt/nfs/esus/www
/mnt/nfs/esus/home 145G 112G 26G 82% /vz/root/101/home
/mnt/nfs/esus/students
145G 31G 107G 23% /vz/root/101/students
/mnt/nfs/esus/www 55G 11G 43G 20% /vz/root/101/www
[root@hprack6 ~]#
(after starting the vps - vps)
[root@web2 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
simfs 5.0G 426M 4.6G 9% /
nfs 145G 112G 26G 82% /home
nfs 145G 31G 107G 23% /students
nfs 55G 11G 43G 20% /www
[root@web2 ~]#
(after stopping vps - physical host)
[root@hprack6 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/cciss/c0d0p1 30G 1.8G 27G 7% /
none 1012M 0 1012M 0% /dev/shm
esus:/students 30G 1.8G 27G 7% /mnt/nfs/esus/students
esus:/home 30G 1.8G 27G 7% /mnt/nfs/esus/home
esus:/www/htdocs 30G 1.8G 27G 7% /mnt/nfs/esus/www
[root@hprack6 ~]#
Notice how all of info for the nfs mounts has chaanged and oddly enough they reflect the / filesystem rather than their real values? CDing into those dirs and doing an ls shows NO files... everything has disappeared. When I umount the dirs by hand they say they aren't mounted... yet they disappear from the df listing... and then I mount -a and they get mounted correctly again.
Here are the contents of my 101.mount script:
#!/bin/bash
#
# 101.mount - script to bind nfs mounts of physical host
# if one of these files does not exist then something is
# really broken
[ -f "/etc/sysconfig/vz-scripts/101.conf" ] || exit 1
# If home dirs are not mounted we exit with error
mount --bind /mnt/nfs/esus/home /vz/root/101/home
mount --bind /mnt/nfs/esus/students /vz/root/101/students
mount --bind /mnt/nfs/esus/www /vz/root/101/www
exit $?
Here are the contents of my 101.umount script:
#!/bin/bash
# if one of these files does not exist then something is really broken
[ -f "/etc/sysconfig/vz-scripts/101.conf" ] || exit 1
# umount nfs mounts
umount /vz/root/101/home
umount /vz/root/101/students
umount /vz/root/101/www
exit $?
Any idea what is going on? Sorry for the bad formatting. The <pre> tag doesn't seem to work for me here.
I'm not sure if this is related to the test kernel or if I had the same problem with the stable kernel. I installed the new vzctl with the migration features... which requires the test kernel. If I reboot and run the stable kernel am I in need of downgrading vzctl anv vzctl-libs?
