Cb Response 6.1.x
/var/cb/data reaching 90-92% of disk capacity up from 70% after upgrading to 6.x
There have been major changes to the purging mechanism in 6.x. The disk reaching a little over 90% is completely normal in 6.1. The default settings for MaxEventStoreSizeInPercent have increased from 70% from 5.x to 90% in 6.x since the event cores are handled differently and no longer require the additional space while merging segments and purging data.
If you feel uncomfortable with MaxEventStoreSizeInPercent set to 90 this setting be reduced, just bear in mind this will negatively affect your retention. This setting is located in /etc/cb/cb.conf. You can check here for more information:
