Which file systems support UNMAP on a Linux server connected to an XtremlO cluster?

For Linux servers connected to an XtremIO cluster, the file systems that support the UNMAP command include Ext3, Ext4, and XFS. The UNMAP command allows these file systems to inform the storage array about blocks that are no longer in use, facilitating better space reclamation and efficiency in storage management.

Dell EMC documentation on XtremIO configurations for Linux environments confirms the support for UNMAP with these specific file systems.

Linux kernel documentation also supports the use of UNMAP/TRIM operations with Ext3, Ext4, and XFS for storage optimization.
