Hi All,
I have a non-VZ NFS server with a few exports that I use autofs/automount to mount /home and /software as needed. I am having issues getting autofs to work properly on a VZ-VPS
/usr/sbin/automount --timeout=60 /home file /etc/auto.home
[root@qavmXX ~]# !ps
ps ax | grep auto
27830 ttyp0 S 0:00 /usr/sbin/automount --timeout=60 /home file /etc/auto.home
27835 ttyp0 S+ 0:00 grep auto
[root@qavmXX ~]# ls -l /home/bkosick
ls: /home/bkosick: No such file or directory
There's no corresponding error in /var/log/messages
autofs works just fine on the HW node.
Anyone run into this before? I've read that VZ has issues with NFS server (SW-Soft thinks that NFS is too unstable under linux!) but that the client should work.
[Edit]
The Node is running FC5/2.6.16-1.2111_FC5.026test012smp the VPS is running RHEL4
Also, I just read a threat stating that there are 2-3 kernel patches to apply before NFS clients will work. Is this true? and if so where do I get them?

1. In OpenVZ kernel from rpm autofs is off, so
if you want to use autofs on HOST with OpenVZ you should
recompile your kernel with CONFIG_AUTOFS_FS, CONFIG_AUTOFS4_FS
parameters on.
2. However autofs (and nfs) are not virtualized,
so you can't use it inside VE.
3. You can mount autofs somethere on HOST,
and then do --bind mount inside any VE you wish.
May be such scenario passes for you.
4. Yeap, there were some patches here at forum,
that makes autofs/nfs available in VE. Try to use search.
However, after such patching you kernel becomes unsecure.
HTH, vass.

OK,
I've tested it out, and it doesn't seemd to work very well. I reported earlier that the autofs worked on the HW node with the fedora kernel... Well it does kinda...
For example. After starteing autofs on the HW node, you can do a "ls /home/bkosick" and it works fine. However if you immediately do the same thing on another user "ls /home/lchamp". It comes back with "No such file or directory". Wait a few minutes, and do the "ls /home/lchamp" command it suddenly works. Note that /home/bkosick is still mounted.
so with these still mounted, I perform the mount --bind command
mount --bind /home /vz/root/334/home
then enter the VPS, vzctl enter 334
and do an "ls /home/bkosick" it comes back with no such file or directory.
ls bkosick
ls: bkosick: No such file or directory
-bash-3.00# ls /home/bkosick
ls: /home/bkosick: No such file or directory
-bash-3.00# cd /home/bkosick
-bash-3.00# ls
ls: .: No such file or directory
Doh!
