Unable to extend a disk

[jgillfeather]

Hi all,

was wondering if anyone has seen this when using vmfsktools to extend a disk -

Failed to extend disk : File to large (1769481)[/b]

Disk is currently 250Gb or so, there is on a 1.4TB free on the LUN, formatted at max block size in VMFS.

Guest is powered off, and i even tried moving the guest to a new LUN, same issue.

Also weirdly since moving the VM to another LUN, the original LUN still has a folder with the name of the VM, and in it is a VMSS file that is huge - over 4GB.

VM is up and running again, and reporting its location as the new LUN aok.

Any have any clues as to what I've done here? Kudos and as many points as I'm allowed to give on offer....

How big do you want to make it? I would try creating a new VMDK file the size you want it to be, see if that will create.

700GB.

Good call, will give that a try.

Hello,

Have you suspended this VM at all? How much memory is assigned to it?

.vmss is a suspend file.

If there are snapshots or the VM is in suspend mode you may not be able to extend the VMDK.

Best regards,
