I had a failure trying to repartition an external drive (a Drobo array) using Disk Utility. Now Disk Utility says my drive is 8.8 TB, but it has only one partition on it using 5.4 TB using up "all" of the space (according to the pie chart). I've been trying to increase the size of that partition to 6.4 TB with no luck.
diskutil shows this:
/dev/disk3 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *8.8 TB disk3 1: EFI EFI 209.7 MB disk3s1 2: Apple_HFS Drobo Time Machine 8.8 TB disk3s2
But df shows this:
/dev/disk3s2 4.9Ti 4.9Ti 26Gi 100% 13373254 4281594025 0% /Volumes/Drobo Time Machine
Why is one showing me 8.8 TB while the other shows 4.9 TB? How can I increase disk3s2 to use more of the physical drive? Obviously I don't want to use all 8.8 TB because I don't really have that much physical storage. But I do have more than 6.4.
