We have a Dell PowerEdge 1900 running ESXi 4.0. The server has 16GB RAM with a Dell PERC 5/i Integrate RAID Controller. We orinially had 5x146 in RAID5 w/Hot Spare. That left us with a formatted Datastore capacity of 403.64GB. We have recently added an additional drive.
When in the datastore properities I can see that the total capacity currently is 403.50GB. The Local DELL Disk shows a capacity of 544.50GB. I have attempted to increase the Total Capacity but there is no space available. Given the scenario, is there an easy way to extend the datastore capacity or I am looking at having to move off all the guests and rebuild ESXi?
