Hi all,

i have a problem with vzdump and suspend.

cat /proc/version
Linux version 2.6.26-1-openvz-686 (Debian 2.6.26-13lenny2) (dannf@debian.org) (gcc version 4.1.3 20080704 (prerelease) (Debian 4.1.2-25)) #1 SMP Fri Mar 13 20:20:40 UTC 2009

vzctl --version
vzctl version 3.0.22

my problem is that only one vz can't go into suspend:

vzdump --compress --dumpdir /mnt/backup/OPENVZ/host/ --tmpdir /var/vztmp/ --suspend -all

205: Nov 09 04:11:21 INFO: Setting up checkpoint...
  205: Nov 09 04:11:21 INFO:  suspend...
  205: Nov 09 04:11:21 INFO: Can not suspend VE: Device or resource busy
  205: Nov 09 04:11:21 INFO: Checkpointing failed
  205: Nov 09 04:11:27 ERROR: Backup of VM 205 failed - command '/usr/sbin/vzctl chkpnt
205 --suspend' failed with exit code 16

The vz has no nfs connections.

Do you have any ideas?

Maybe you "stepped" on this container, i.e. there is a process in host system which is currently in CT directory. Try to suspend manually, see what's in dmesg, find out the reason.

vzctl chkpnt 205 --dumpfile /mnt/backup/OPENVZ/dump205
Setting up checkpoint...
        suspend...
Can not suspend VE: Device or resource busy
Checkpointing failed

the latest dmesg messages are

[7431996.225352]  CIFS VFS: No response for cmd 114 mid 17110

I think thats not very helpful?

What do you mean with "stepped" this container?
what is the CT Directory?

I've executed the command
with strace and found there following file:

more /proc/cpt
Ctx      Id       VE       State
eaf79000 000000cd 205      2

Does anybody know what this mean?
