snapshot mode goes to suspend...

[valshare]

Hi,

i have one kvm machine, that goes into suspend mode if it will backup. The machine ist installed on an iscsi target. Other kvm machines didnt go to suspend mode that are on the same iscsi target, if it will backup. The suspend mode makes a little bit trouble here with one service that is installed on the machine.

Logfile from the backup:

Why the machine goes to suspend?

Why the machine goes to suspend?

Bescause it is using 2 disks. The only way to make a consistent snapshot over 2 disk is to shortly suspend the VM.
