I found that it seems to be my issue reported on Oracle forum here . Solution is to manually restart o2cb service and remount filesystems:
Code:systemctl restart o2cb.service
I can add this to cron temporary but it it's rather lame solution. I would like to fix this before upgrading the rest of nodes. Please help.
===UPDATE===
Problem solved (enable services to get it working)
I seem to hit the same issue in this issue
I enabled `o2cb.service` already but it didn't help in my case. Did you enable other services as well? thanks for sharing
