Reclaiming Unused
Storage SpaceLast Updated December 16, 2024
When VMFS
datastores reside on thin-provisioned LUNs, you can use ESXCLI commands to
reclaim the unused logical blocks of a thin-provisioned LUN formatted with
VMFS.
When you run the commands, you
must specify the volume label
--volume-label
or the volume ID
--volume-uuid
but you cannot specify both.
In each iteration, the command issues unmap commands to
the number of file system blocks that are specified by the optional
reclaim-unit
argument, which defaults to 200.The following examples
illustrate how to use the command.
