esxi 4.1 can not expand datastore lun detected as snapshot

[gwsilliman]

I am attempting to expand an existing datastore located on a direct attached raid 5 array.  I have added space on the array, which esxi recognizes, however I can not expand the datastore to consume the new free space, nor can I create a new datastore with the free space.

I am using 5 250gig drives, so I am not running up against the 2tb barrier.  They are in an external array chassis, attached to an RR2722 sas controller.

When I open the properties of the datastore, the expand open is grayed out.

Any thoughts as to how I can expand my datastore?

Thank you

Some assistance from folks at expert exchange suggest perhaps the log line stating the lun is detected as a snapshot is causing the issue.

This is a local lun, direct attached storage.  I have no idea why it would be detected as a snapshot.  I used esxcfg-volume -l to list any snapshot luns and none were listed.

Any help?

Still unresolved, expect to have to rebuild the datastore. Not sure if this is a limitation of the free license or a bug. Thanks for all the comments.
