Hi,
I've recently started experimenting OpenVZ and ran into this issue.
On a Debian etch host, running an etch guest when I do a reboot inside a VPS, I can no longer destroy it (or remove the folder).
On a server that has just rebooted, and that has been recently installed with a kernel from download.openvz.org.
/var/lib/vz is a symlink to /vz and /vz is an ext3 partition.
server1:~# uptime

I then manually ran both scripts inside /etc/cron.d
/usr/share/vzctl/scripts/vpsnetclean then /usr/share/vzctl/scripts/vpsreboot so that the VPS comes back faster.

A vzctl restart xxx will also do the same.

lsof on the private area did not return anything.
Has anyone experienced the same behavior?

Hi,
1. What version of vzctl do you use?
2. If it is possible can you please conduct this experiment with the latest version of vzctl?
3. | Quote: |

|
Does it mean that lsof output doesn't contain any process which uses some file from ve private area?
4. In the last case please pay attention at the message | Quote: |
vzquota : (warning) Quota is running for id 125 already
|
try
a) vzctl stop 125
b) vzquota off 125
c) vzquota drop 125
d) vzctl start 125
e) vzctl restart 125
f) vzctl destroy 125
Thank You!

server1:~# dpkg -l | grep vz
ii linux-image-2.6.18-openvz-amd64 028.18.1-2.6.18-12-1 Linux kernel binary image for version 2.6.18
ii vzctl 3.0.11-13 server virtualization solution - control too
ii vzdump 1.0-2 OpenVZ backup scripts
ii vzquota 3.0.8-2 server virtualization solution - quota tools

By latest vestion do you mean a development version? Sure I can try it. Just let me know where to grab it from.

It seems that if the VE is stopped (even a vzctl stop) this happens.
Here is what I just tried (following the sequence you've put:
server1:~# vzctl create 105 --
server1:~# vzctl create 105 --ostemplate debian-4.0-amd64-minimal
Creating VPS private area: /var/lib/vz/private/105
Performing postcreate actions
VPS private area was created
server1:~# vzctl start 105
Starting VPS ...
VPS is mounted
Setting CPU units: 1000
VPS start in progress...
server1:~# vzctl stop 105
Stopping VPS ...
VPS was stopped
VPS is not mounted
server1:~# vzquota off 105
server1:~# vzquota drop 105
server1:~# vzctl start 105
Starting VPS ...
Initializing quota ...
VPS is mounted
Setting CPU units: 1000
VPS start in progress...
server1:~# vzctl restart 105
Restarting VPS
Stopping VPS ...
VPS was stopped
VPS is not mounted
Starting VPS ...
vzquota : (warning) Quota is running for id 105 already
VPS is mounted
Setting CPU units: 1000
VPS start in progress...
server1:~# vzctl stop 105
Stopping VPS ...
VPS was stopped
VPS is not mounted
server1:~# vzquota off 105
server1:~# vzquota drop 105
server1:~# vzquota show 105
vzquota : (error) Can't open quota file for id 105, maybe you need to reinitialize quota: No such file or directory
vzquota : (error) Quota file must exist for show command
server1:~# vzctl destroy 105
Destroying VPS private area: /var/lib/vz/private/105
Can't move /var/lib/vz/private/105 -> /var/lib/vz/tmp/X8zw8wd: Device or resource busy
Even though after the vzctl stop, vzquota off, and vzquota drop the vzctl start no longer complains that the quota is running, if I try to destroy it, it still won't let me.
