OpenVz Snapshot work from GUI but not from Vzdump command

[krok]

Hi,

i have upgrade to proxmox 2 Rc1, i have test a vzdump dump in command line :

# vzdump 102 -mode snapshot
INFO: starting new backup job: vzdump 102 --mode snapshot
INFO: Starting Backup of VM 102 (openvz)
INFO: CTID 102 exist mounted running
INFO: status = running
INFO: mode failure - unable to detect lvm volume group
INFO: trying 'suspend' mode instead
INFO: backup mode: suspend


but this work fine in GUI :

INFO: starting new backup job: vzdump 102 --mode snapshot --compress lzo --storage backup --node phy1
INFO: Starting Backup of VM 102 (openvz)
INFO: CTID 102 exist mounted running
INFO: status = running
INFO: backup mode: snapshot
INFO: ionice priority: 7
INFO: creating lvm snapshot of /dev/mapper/pve-data ('/dev/pve/vzsnap-phy1-0')
INFO: Logical volume "vzsnap-phy1-0" created
INFO: creating archive '/backup/pve//dump/vzdump-openvz-102-2012_02_17-20_59_29.tar.lzo'

an idea ? thanks for your help.

You run totally different commands:

# vzdump 102 -mode snapshot

and

INFO: starting new backup job: vzdump 102 --mode snapshot --compress lzo --storage backup --node phy1

So what is the question?

Note: try "--storage backup"

# vzdump 102 --mode snapshot --compress lzo --storage backup --node phy1
INFO: starting new backup job: vzdump 102 --mode snapshot --compress lzo --node phy1 --storage backup
INFO: Starting Backup of VM 102 (openvz)
INFO: CTID 102 exist mounted running

INFO: starting first sync /var/lib/vz/private/102/ to /backup/pve//dump/vzdump-openvz-102-2012_02_18-21_14_23.tmp

why the lvm volume was not detected with the vzdump command line ?

 

[dietmar]

And that still works when you run from the GUI?

 

[krok]

yes

 

[dietmar]

yes

That executes the same code, so I have no idea why that fails.
