Unable to expand VMFS partition

Today I was asked to expand a local datastore of a ESXi 4.1. Expanding a disk is normally no problem when you are able to increate the size of the disk. After increasing the disk size you should be able to increate the partition size.

The ESXi was managed by a vCenter 5.0.  On the storage adapter I did a RESCAN data stores after the disk size was increased.  Then I went into the DATASTORE properties and I saw following

 

 

 

 

 

 

 

 

 

 

 

 

This above view was via a vCenter connection.  Then I found following VMware KB which told me to make a direct connection to the ESXi host.  After going to into the datastore properties I found out that I could increase.

 

 

 

 

 

 

 

 

 

 

When I selected this local datastore and finished the expansion I saw following result in the vSphere Client direct to the ESXi and via vCenter.

 

 

 

 

 

 

 

 

 

 

Lucky for the customer this expansion went OK.

Hopefully if you have this problem this KB article fixes also your problem.

Success
