|Persisting Table Data to GemFire XD Disk Stores / Overview of Disk Stores|
At creation, each operation log is initialized at the disk store's MAXLOGSIZE value, with the size divided between the crf and drf files. GemFire XD only truncates the unused space on a clean shutdown (for example, gfxd server stop or gfxd shut-down-all).
After the oplog is closed, GemFire XD also attempts to created a krf file, which contains the key names as well as the offset for the value within the crf file. Although this file is not required for startup, if it is available, it will improve startup performance by allowing GemFire XD to load the entry values in the background after the entry keys are loaded.

The system rotates through all available disk directories to write its logs. The next log is always started in a directory that has not reached its configured capacity, if one exists.
Even though the configured directory size limit has been exceeded a new oplog will be created. The current limit is of XXX. The current space used in the directory is YYY.
Disk is full and rolling is disabled. No space can be created
