	| 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!
