The vps is locked by another user [message #32281]

Hello,

I have following error when i try to start some of our vps:

The vps konkoor87.vm is locked by another user. This would also be because you had interrupted an earlier activity that would take long time to complete. HyperVM has waited 15 seconds for the other process to finish. Please try after sometime.

I cant start vps with following too:
vzctl --skiplock start 380

and see following:
Starting VE ...
vzquota : (error) can't lock quota file, some quota operations are performing for id 380
vzquota on failed [7]

I see following in /vz/lock too:
310.lck 320.lck 330.lck 370.lck 380.lck

How can resolve this issue?

Thanks

Hi,

try this:
vzctl stop 380
vzquota off 380 (vzquota -f off 380).

Hi,

Is it possible to remove 380.lck file and then "vzquota drop 380"? Then quota must be recalculated.

It's not ok too:

[root@ lock]# rm -rf 380.lck
You have new mail in /var/spool/mail/root
[root@ lock]# ls
320.lck 330.lck
[root@m5088 lock]# vzquota drop 380
vzquota : (error) can't lock quota file, some quota operations are performing for id 380

Hi,

You shouldn't have been simply delete the file.

Ok,
1. Could you possibly show:
cat 320.lck
cat 330.lck

there should be some numbers.
could you please the check:
ls /proc/number
ps aux | grep number

1- Yes, it me. im use "vzctl start 380" after reboot server for start this vps and see:
[root@ ~]# vzctl start 380
Starting VE ...
vzquota : (warning) Incorrect quota shutdown for id 380, recalculating disk usage

But its taking unusally long time for recalculating disk usage and ctrl+c is not work for cancle this command too.

2- A) cat: do_wait
B) strace: Process 23408 attached - interrupt to quit wait4(23423,
0x7fff9da80e84, 0, NULL) = ? ERESTARTSYS (To be restarted)
--- SIGINT (Interrupt) @ 0 (0) ---
wait4(23423, 0x7fff9da80e84, 0, NULL) = ? ERESTARTSYS (To be restarted)
--- SIGINT (Interrupt) @ 0 (0) ---
wait4(23423, 0x7fff9da80e84, 0, NULL) = ? ERESTARTSYS (To be restarted)

wait4(23423,

Hi,

1.
recalculating disk usage - may be a very long process.
May be it worth waiting.
If this process doesn't wake up you can get the call trace of vzctl process via Alt-SysRq-T command but it shows a lot of information so there is a chance that syslog won't save appropriate information in /var/log/messages. If you want you can set serial console.

2.
More radical way is killing vzctl process.
I don't know if it helps. But you can try.
Try to off and drop quota after killing vzctl (vzquota off 380 (or vzquota off 380 -f), vzquota drop 380). Then try to start again.

by the way could you please estimate disk space of that VE. Is it huge?
