upon update, I got a
Transaction check error:
installing package openvswitch-2.5.3-126.96.36.199.xcpng.x86_64 needs 1 inodes on the /var/log filesystem
Which translated that the ovsdb-server logs were too many and had filled up my log storage.
I had to run:
find . -name "ovsdb*" -delete
because rm couldn't handle so many ovsdb log files to delete.
