I am getting this error when attemting to shrink a 67gb partition to 45gb on a 135gb disk. This is a HP proliant server with a Smart Array 641 controller. The disks are in a hardware raid 5. Originally there were 3 disks in the array and 2 more were added at a later date and raid was extended to drives. The partition however was not extended. The extra 2 drives were given their own partition on the raid 5 array. Due to corporate security policy I am unable to run any 3rd party software that sends information about the assets. Any help/workarounds would be appreciated.
