Adjusting NFS Memory Settings

The memory allocated to each Data Fabric service is specified in the /opt/mapr/conf/warden.conf file, which Data Fabric automatically configures based on the physical memory available on the node. You can adjust the minimum and maximum memory used for NFS, as well as the percentage of the heap that it tries to use, by setting the percent, max, and min parameters in the warden.conf file on each NFS node. Example:


The percentages need not add up to 100; in fact, you can use less than the full heap by setting the heapsize.percent parameters for all services to add up to less than 100% of the heap size. In general, you should not need to adjust the memory settings for individual services, unless you see specific memory-related problems occurring.
