Hi,
We are running Openstack Rocky version. Our instances are getting volume from CEPH (mimic version).
Suddenly one of our compute node got shutdown due to RAM issue. So all instances running on that compute node (linux/windows) got effected. After starting the compute node all services up & running. But instances on that compute node fail to boot. Instances are getting volume from CEPH storage& CEPH is in Healthy state. Please see below log.
Requesting if anyone can help me to solve.
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, Thomas Goirand (zigo) Hi, Thanks a lot for your quick response. ////////////////////// Make sure you have set in nova.conf: resume_guests_state_on_host_boot=True ##### 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, Rony
