Hi,

Make sure you have set in nova.conf:
resume_guests_state_on_host_boot=True

on each of your compute nodes.

Also, it's wise to have instance_usage_audit=True

I hope this helps,

Hi,
Thanks a lot for your quick response. 

////////////////////// Make sure you have set in nova.conf:

##### this settings we are not using. We shall check.


////////////////////// Also, it's wise to have instance_usage_audit=True

##### already configured.


Please help if there is any way to repair effected instances volume.


Thanks & B'Rgds,
