Hello, I've been having issues with the host server crashing/freezing (not sure what you'd call it) since did an update 5 days ago Start-Date: 2016-07-20 18:43:11 Commandline: apt-get upgrade -y Upgrade: libanyevent-http-perl:amd64 (2.21-1, 2.22-1), libxapian22:amd64 (1.2.19-1...

@fabian: The fix I tried (just checking if the /proc/$PID dir exists) seems to have worked great for me so far The other containers I set up havent hung so far, but it's kinda hard without production data to give the cronjob something proper to work on I'll try and see if I can sort something...

From what I gather it's spinning in a loop waiting for processes to finish There's a isProcessStillRunning function.. which gets all pids via some ps/awk trickery and then searches for the pid in there - probably the best way that could feasably be solved *sigh* an exists(/proc/$PID) call would...

They should not suspend the container, but they briefly (if everything goes right, not noticable) freeze the container to create the snapshot volume . If stuff goes wrong.. it hangs indefinitely trying to freeze the container

I'm on a local storage aswell (thought i had mentioned that somewhere, sorry!) Just an ext3 file system on a different hdd Oh yeah, would also be good if it would handle the following error more gracefully (just restarting the backup makes it work normally) INFO: Starting Backup of VM 102...

The container is a converted openvz debian wheezy one, updating is on my todo list, but I havent gotten to it yet Network traffic to the vm looks fairly tame across the board Freezes are 29th and 3rd around 6am As for the ps loop.. couldn't really get much resolution out of it (see attached...

It's happening again Stacktrace where lxc-freeze is stuck: (gdb) bt #0 0x00007fcd89ebc060 in __nanosleep_nocancel () at ../sysdeps/unix/syscall-template.S:81 #1 0x00007fcd89ebbf14 in __sleep (seconds=0, seconds@entry=1) at ../sysdeps/unix/sysv/linux/sleep.c:137 #2 0x00007fcd8ac1d202 in...

Ah I see it freezes the vm while waiting for the filesystem to create the snapshot volume I still had the pstree output saved from when it froze: ├─cron───cron───vzdump───task UPID:host:───lxc-freeze # <-- hanging lxc-freeze ├─lxc-start───init─┬─atd # <-- container in question...

Same thing happened again, got nothing to add really

Not sure if this is related, but I just had a lxc container freeze during snapshot mode I noticed the machine wasnt responding so I checked what was going on - after a bit of searching I noticed an lxc-freeze command for the vm (the backup had been idling for a good 4 hours, usually takes 20min...

I do know how to use rsync, but I need to execute rsync (or any other syncronization utility) AFTER the backups have been created. I was asking if there was an easy/recommended way of executing a command once the backup task has been finished

Yes, that is what I am trying to do. Is there a recommended way to place a hook so rsync gets executed once the backup is done?

Hello, Currently we have multiple backup jobs, one per storage. This proves to be quite the performance hog though. There are constantly (during morning-noon) backup jobs running - even some timing out due to not being able to aquire the vzdump lock in time. What is the recommended way to...
