We have a 2008 R2 server with 3 - 250 GB drives in RAID 5 (465 GB)
Disk space partitioned as follows:
30 MB unparitioned
3 GB recovery partition
40 GB OS partition
421 GB data partition
We are running low on the OS partition - only 650 MB free.
There is 363 GB free on the data partition.
What would be the easiest / safest / most economical way to increase the OS partition size?
