trim.free_space_threshold
Background
The TRIMPush gatherer will regularly check that there’s enough free space on disk to continue crawling. If not, it will stop cleanly in order to prevent a crash of the crawl when the server will run out of disk space.
This setting controls how many disk space should remain (in MB) for the crawler to continue. To configure
which drives should be excluded from this check please consult trim.free_space_check_exclude.
Setting the key
Set this configuration key in the search package or data source configuration.
Use the configuration key editor to add or edit the trim.free_space_threshold key, and set the value. This can be set to any valid Long value.
