The maintenance on the T: drive is taking substantially longer than expected.  The removal of an old backup snapshot is taking an extended period of time. The server cannot be re-instated until the operation is complete.  An update will be posted when the situation changes.


Follow-up (9/15 9:15AM):

The maintenance is complete.  The backup snapshot deletion took exceedingly longer than expected.  The process completed at 6:15 AM.  After verifying there were not adverse effects the original maintenance work to remove old volumes was done.  Service was restored at approximately 9:00 AM.  We have changed the server configuration so future snapshots tasks should not take undue time.
