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

AExt3, Ext4, and XFS

BReiserFS, Ext4, and ZFS

CExt4, XFS, and ZFS

DReiserFS, Ext3, and XFS

Show Suggested Answer

Suggested Answer: A

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.

Ext3 is outdated, not sure why it's even mentioned here.

Based on my experience, I'd say the best approach is to focus on the file systems that are commonly used with enterprise-grade storage solutions like XtremlO. That narrows it down to Ext4, XFS, and possibly ZFS.

I'm a bit confused by this question. I'm not too familiar with the UNMAP feature or how it relates to different file systems. I'll need to do some quick research to figure this out.

UNMAP? Is that what happens when you accidentally delete the Linux kernel? I'll stick with C, it sounds the most legit.
