I recently upgraded my RAID setup. I had one RAID1 array with the system on it and one RAID5 array with data on it. I replaced each hard drive, one by one, with a drive double its size and let the array rebuild before switching the next hard drive. This worked out fine. Next I hoped to resize the partitions into the unallocated space. Acronis Disk Directory Server does not seem to be able to do this. Although it shows the unallocated space on the same disk as the partition I want to expand, it does not let me resize the partition into that space. I can only create a new partition in the unallocated space. It seems that the two spans of space on the hard drive are not able to be joined. Can anyone confirm or deny this? Has anyone tried something similar?
