Description

Some devices have security feature of "Full Disk Encryption" enabled on disks.
For such cases, punch hole feature inside Ext type filesystem is not supported on most of the kernel versions.
To run without hole punching (at the cost of some efficiency and scalability), Kudu needs to be reconfigured to use the file block manager.

This Jira is to track the work to note this in Kudu documentation if not already present.
Also, if possible check if error message can be made more clear when kudu cluster configuration hits this issue.
