Details

You may observe one of the following symptoms when using vSphere ESXi/ESX 4.x/5.x:

Add storage wizard shows a VMFS partition, but does not show a VMFS label.

Add storage wizard only supplies the option to reformat the volume, which would lead to a loss of all data.

Add storage wizard does not provide an option to Resignature the VMFS Datastore.

The /var/log/vmkernel or /var/log/messages log reports these VMFS Datastores as snapshot volumes.

Solution

To resolve the problem with LVM Signature Mismatch, resignature or force-mount the Datastore.

Using esxcfg-volume or vicfg-volume

The esxcfg-volume and vicfg-volume commands are used to resignature or force-mount a VMFS Datastore. For more information on usage, see the vSphere Command-Line Interface documentation and the vicfg-volume reference.

For example:

Obtain a list of volumes detected as snapshots or replicas using the command:

vicfg-volume [connection_options] --list

Resignature or force-mount a volume using one of the commands:

vicfg-volume [connection_options] --resignature VMFSDatastoreUUID

vicfg-volume [connection_options] --persistent-mount VMFSDatastoreUUID

This writes a new signature down to the LVM / VMFS Datastore. The volume may be brought back to a usable state. Paths to files on resignatured Datastores must be updated manually.

If esxcfg-volume or vicfg-volume doesn't work

If resignaturing or force-mounting a volume using the esxcfg-volume or vicfg-volume command fails, consider the reason: Failures may happen due to active I/O to the device, or because of another low-level problem.

Try the following in case of failure:

Take note of any errors produced by the esxcfg-volume or vicfg-volume command.

Attempt the operation from a different ESXi/ESX host.

vMotion all VMs off one ESXi/ESX host, reboot it, and attempt the operation from that host.

Consider whether there is an additional problem with the integrity of the VMFS Datastore.
