The "/ifs/data/Isilon_Support/pkg" directory is the default location to write the log gather packages. Those files and packages are used for troubleshooting and technical support. This directory should not be removed. 

The "/ifs/data/Isilon_Support/datamover" directory is the directory that stores data for the Data Mover service, a component of SmartSync. SmartSync is used for data migration and backup. This directory should not be removed.

All other files and folders within "/ifs/data/Isilon_Support/" were created throughout the lifetime of the cluster by either Dell Technical Support or the cluster Administrators. Dell Technical Support often uses "/ifs/data/Isilon_Support/" as a temporary holding place for troubleshooting scripts, test files, and temporary backup folders. By policy, Dell Support personnel are not allowed to delete data from a cluster, so unneeded files are often moved to this directory as a precaution.   

It is at the discretion of the cluster Administrator to remove the extra data within the Isilon_Support folder. Keep in mind, if there are active Support Cases with Dell Technical Support, some of the files or folders within "/ifs/data/Isilon_Support/" may be needed. If there are any Questions or Concerns, contact Dell Technical Support.
