The cb-enterprise service will not start with no disk space available on Cb Response server due to purge settings in past
df –h shows that the /var/cb is 100% used and only a small disk space is left and not enough to allow a service to start.
There’s a defect on version of 4.2.3 to v5.1.0 where it doesn't apply default values for purging. This is addressed on a hotfix but requires the CB server to be on at least v5.0.0 patch 3. CB v5.0.0 patch 4 and 5.1.0 patch 1 will both include the hotfix.

du -h /var/cb/data/ --max-depth=1
Check folder size in /var/cb/data/solr since most of the disk usage is here under the data folder:
