Unable to delete a flat-vmdk file from VMFS5 volume

Start by identifying the server whose VMkernel may be locking the file.

# vmkfstools -D /vmfs/volumes/UUID/VMDIR/LOCKEDFILE.xxx

 > Hostname vmkernel: gen 532, mode 1, owner xxxxxxxx-xxxxxxxx-xxxx- zzzzzzzzzzzz mtime xxxxxxxxxx]

zzzzzzzzzzzz gives the MAC adres of the server locking the file.

# lsof | grep -i LOCKEDFILE.xxx

OR

# vmkvsitools lsof | grep LOCKEDFILE.xxx

You see output similar to:

11773 vmx 12 46 /vmfs/volumes/Datastore_Name/VirtualMachineName/ VirtualMachineName-flat.vmdk

kill -9 PID (in the above case 11773)

The trust relationship between this workstation and the primary domain failed

Sometimes, and in my case after a failes “Migrate to production” of a server (as the ESX host died on me while migrating). After a Full VM Recovery the server won’t logon to the domain.

What to do:

Open a Command Prompt as Administrator (logged on localy)

And enter following command:

netdom.exe resetpwd /s:<server> /ud:<user> /pd:*
Where:
<server> is the domain controller of the domain.
<user> is the domain\user administrator user for the domain.
the pd:* will ask you for the password.

You should recieve a success.

REBOOT and logon to the domain.
