Hi,
I have an issue {or I think it is} when I am in a VE
I notice that the following mount points are mounted 2
and sometimes 3 times...
/var/run
/var/lock
root@mysqlvz01:/# df -h
Filesystem Size Used Avail Use% Mounted on
simfs 4.0G 470M 3.6G 12% /
tmpfs 1.9G 32K 1.9G 1% /var/run
tmpfs 1.9G 0 1.9G 0% /var/lock
tmpfs 1.9G 0 1.9G 0% /dev/shm
tmpfs 1.9G 32K 1.9G 1% /var/run
tmpfs 1.9G 0 1.9G 0% /var/lock
tmpfs 1.9G 32K 1.9G 1% /var/run
tmpfs 1.9G 0 1.9G 0% /var/lock
tmpfs 1.9G 32K 1.9G 1% /var/run
tmpfs 1.9G 0 1.9G 0% /var/lock
tmpfs 1.9G 32K 1.9G 1% /var/run
tmpfs 1.9G 0 1.9G 0% /var/lock
Is this normal?
Current Setup:
Server: Ubuntu 8.04
Vzkernel: Linux vmserver 2.6.24-19-openvz #1 SMP Sat Jul 12 01:13:47 UTC 2008 x86_64 GNU/Linux
vzctl: 3.0.22
VE: ubuntu-8.04-amd64-minimal
Hardware:
CPU: Intel core 2 duo e6400
Mem: 4GB

Well i'm not using ubuntu in openvz, but out of curiosity i took a look at normal desktop ubuntu installation
# fgrep /var/run /proc/mounts
tmpfs /var/run tmpfs rw,nosuid,nodev,noexec 0 0
tmpfs /var/run tmpfs rw,nosuid,nodev,noexec 0 0
tmpfs /var/run tmpfs rw,nosuid,nodev,noexec 0 0
# fgrep /var/lock /proc/mounts
tmpfs /var/lock tmpfs rw,nosuid,nodev,noexec 0 0
tmpfs /var/lock tmpfs rw,nosuid,nodev,noexec 0 0
tmpfs /var/lock tmpfs rw,nosuid,nodev,noexec 0 0
#
So this looks like unrelated to openvz ubuntu bug probably
in init.d scripts
# egrep -e 'do.*/var/(lock|run)[[:space:]]' /etc/init.d/*
/etc/init.d/mountkernfs.sh: domount tmpfs "" /var/run -omode=0755,nodev,noexec,nosuid
/etc/init.d/mountkernfs.sh: domount tmpfs "" /var/lock -omode=1777,nodev,noexec,nosuid
/etc/init.d/mtab.sh: domtab tmpfs /var/run "varrun" -omode=0755,nodev,noexec,nosuid
/etc/init.d/mtab.sh: domtab tmpfs /var/lock "varlock" -omode=1777,nodev,noexec,nosuid
#
But # fgrep /var/lock /etc/mtab
varlock /var/lock tmpfs rw,noexec,nosuid,nodev,mode=1777 0 0

So any suggestions on how this can be resolved.
Here is the output from a VE.

Could this potentially be a problem?

I'm this having the same issue.
I would discard the option of an issue with the ubuntu template since I have 2 other VPS in the same server, based on the same template, without this issue.

tmpfs on /var/run type tmpfs (rw,nosuid,nodev,noexec,relatime)
tmpfs on /var/lock type tmpfs (rw,nosuid,nodev,noexec,relatime)
Any ideas how to sort this out? This is a production environment so I can not be experimenting this with a live server... 
Many thanks!

Hi all.
@TheStig - Thanks for your reply but as I mentioned, the issue is not likely to be related with the template since I have more than 10 VPS created with the same template and only 2 have this problem.
I spend some time trying to find out what was the difference between the VPSs and eventually managed to sort it out:
The only point in common between the 2 VPS showing duplicated mounts was that both had an entry in /etc/fstab with a nfs mount. More, this location was not available anymore as the machine had been removed months ago.
Just removed this entries from the fstab, restarted the VPS and... voilá! No multiple mounts for /var/lock or /var/run.
Hope this helps.

that's quite funny - i never ever use nfs 
i think, at least on my hardware the issue located somewhere here:
on HN
joseph@av-3:~$ ls -al /vz/private/104/etc/mtab

joseph@av-3:~$ ls -al /vz/private/103/etc/mtab
lrwxrwxrwx 1 root root 12 2010-01-25 12:51 /vz/private/103/etc/mtab -> /proc/mounts
joseph@av-3:~$ cat /proc/mounts |egrep "lock|run"

101 - 103 are Ubuntu 8.04 templates created via debootstrap, 104 is running a RHEL4-VPS that i created out of a former physical machine - thats why i guess, that at least in my case, it has something to do with ubuntu/debian-specific init.d's or OSTEMPLATE-scripts.
Bus as I believe the issue to be of an entirely cosmetic nature, I never bothered to try and fix it.
