To purge the file server cache (inodes, blocks, etc), execute:
/opt/mapr/server/mrconfig cache purge fsall
Use this command instead of restarting the file server process because restarting the process might trigger container resyncs.
Just to make Catherine R. Skrbina's post more clear (for those like me ), the fsall parameter in the command should not be misconstrued as something effecting (cache purging) all the file-servers across the cluster. The effect of this command is local only to the node from where it is executed.
