You can resignature a VMFS copy with ESXCLI or with vicfg-volume. See “Resignature a VMFS Copy with
ESXCLI,” on page 34 or “Resignature a VMFS Copy with vicfg-volume,” on page 34.
Resignature a VMFS Copy with ESXCLI
The esxcli storage vmfs snapshot commands support resignaturing a snapshot volume.
Specify one of the connection options listed in “Connection Options for vCLI Host Management
Commands,” on page 19 in place of <conn_options>.
Procedure
1 List unresolved snapshots or replica volumes.
esxcli <conn_options> storage vmfs snapshot list
2 (Optional) Unmount the copy.
esxcli <conn_options> storage filesystem unmount
3 Run the resignature command.
esxcli <conn_options> storage vmfs snapshot resignature --volume-label=<label>|--volume-
uuid=<id>
The command returns to the prompt or signals an error.
What to do next
After resignaturing, you might have to perform the following operations.
n
If the resignatured datastore contains virtual machines, update references to the original VMFS
datastore in the virtual machine les, including .vmx, .vmdk, .vmsd, and .vmsn.
n
To power on virtual machines, register them with the vCenter Server system.
Resignature a VMFS Copy with vicfg-volume
You can use vicfg-volume to mount, unmount, and resignature VMFS volumes.
Prerequisites
Verify that the VMFS copy you want to resignature is not mounted.
Procedure
u
Run vicfg-volume with the resignature option.
vicfg-volume <conn_options> --resignature <VMFS-UUID|label>
The command returns to the prompt or signals an error.
Reclaiming Unused Storage Space
When VMFS datastores reside on thin-provisioned LUNs, you can use ESXCLI commands to reclaim the
unused logical blocks of a thin-provisioned LUN formaed 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 le system blocks that are
specied by the optional reclaim-unit argument, which defaults to 200. For newly created VMFS-5 le
systems, the lesystem block size is always 1 MB. For VMFS-3 le systems or VMFS-5 le systems that were
upgraded from VMFS-3, the lesystem block size could be one of 1, 2, 4, 8 MB.
