vzdump fails - cannot suspend

[JBK]

We tried to backup a VE with:

vzdump --suspend 101

but got the following error:

INFO: suspend vps
INFO: Setting up checkpoint...
INFO: suspend...
INFO: Can not suspend container: Device or resource busy
INFO: Error: file struct is referenced outside 1 2
INFO: Checkpointing failed
ERROR: Backup of VM 101 failed - command '/usr/sbin/vzctl chkpnt 101 --suspend' failed with exit code 16

Any ideas? We can backup if we stop the VE

is this a special container, any additional settings and tweaks?

 

[JBK]

This is a Centos5 container. We ran yum update and installed apache 2.2.11, php 5.2.8, mysql from yum update, proftpd 1.3.1, ncftp, tripwire, and ZendOptimizer. We also added a bunch of perl CPAN modules, and php modules and php required stuff like gd.

so no bind mounts or any other references to external filesystems?

can you backup with snapshop mode (vzdump)?

 

[JBK]

NFS, AUTOFS are off. I tried:

vzdump --dumpdir /var/lib/vz/dump --snapshot 101

and we're still getting failures. Again if we stop the VE from the control panel we can do the dump but not otherwise. Here's the log output:

NFS, AUTOFS are off. I tried:

vzdump --dumpdir /var/lib/vz/dump --snapshot 101

you cannot do a snapshot into the same partition.

see the error message:

ERROR: unable to dump into snapshot

pls use a dumpdir which is outside, e.g. make a dir on the root partition - /backup or mount a remote filesystem like samba.

Hey - that worked. Thanks!!!

How to define de tmp dump directory??

Greetings!!

 

[dietmar]

How to define de tmp dump directory??

# man vzdump

 

[jmjosebest]

# man vzdump

OK, with --tmpdir
but, how to configure in Proxmox? this parameter not run in the Proxmox vzdump...

(root) CMD (vzdump --quiet --stop --compress --dumpdir /vz/backup --mailto xx@xx.com 113)

Thanks!!

Use the admin web interface (gui) to define the backup destination (dumpdir).

 

[jmjosebest]

I say the tmpdir, not the dumpdir.

If i need edit some file, is not a problem

as Dietmar already wrote: 'man vzdump' to see all options so what is the question?

 

[jmjosebest]

in the proxmox gui, there isnt any option to configure the tmpdir.
My question is, if they are any option (editing any file for example) to define this parameter, and when I configure the backup in proxmox, the tmpdir will defined, because by default, there isnt configured...

(root) CMD (vzdump --quiet --stop --compress --dumpdir /vz/backup --mailto xx@xx.com 113)

I need this

(root) CMD (vzdump --quiet --stop --compress --dumpdir /vz/backup --tmpdir /vz/backup --mailto xx@xx.com 113)

Thankss!!!

ok, now I understand your question.

the GUI configure a cron job. you can edit this cron job manually (but this will be overwritten if you change something on the gui).

see /etc/cron.d/

 

[jmjosebest]

Fenomenal!! this is that i need!! Thanks!!!

PD- It's a good idea configure for the new version of Proxmox, this parameter

Again, Thanks very much!!
