Thank you! I'm still a bit jittery though, you know how it goes when you do stuff to your computer that you don't have the pay grade for! BTW, i'm running a RAID 6 array, so to the previous poster - it does work. Thanks again! :) OMG - it works!! Thank you!

I dont' have a RAID running, but had a diskimage that I wanted to expand. After resizing the diskimage, I was not able to resize the volume on the diskimage, with the same 'partition (map) too small' error. I fixed this using your hint, so thanks! One note: because the diskimage had two partitions, one EFI partition and one HFS+ partition, I had to re-add the EFI partition with the extra option -t, specifying the partition type (apparently, Apple_HFS is the default type, so for 'normal' partitions this is not needed) For the EFI partition I had to use: sudo gpt add -b [value] -s [value] -t C12A7328-F81F-11D2-BA4B-00A0C93EC93B /dev/disk[value]. Here, C12A7328-F81F-11D2-BA4B-00A0C93EC93B is the GUID for an EFI partition. (whereas 48465300-0000-11AA-AA11-00306543ECAC is the GUID for a 'normal' Apple_HFS partition) Once again, thanks a lot! Brilliant hint!

Spent a few hours googling before finding this. I have an iSCSI target on ubuntu (using LVM2 and RAID) which I *reduced* from 3TB to 1.6TB and diskutil was able to shrink the volume just fine. Then when I enlarged it to 6TB later, diskutil resizeVolume was failing with the partition map too small 9939 error. I tried running it with limits and it showed 3TB. I guessed what was happening but didn't know how to fix it until finding your post. Thanks very much! Thank you so much. Spent a few hours googling before finding this.

Yet I got stuck at claiming the newly created disk space. Thanks to this post. It really works!

Neither Apple or the raid card manufacturer could help me without erasing my existing 2 TB RAID5. That was a non-starter. Thanks again. I too must thank you for this invaluable advise.

I was able to extend our iSCSI volume, finally. I've printed it to PDF and added it to our internal Kbase at my work. Thank you. This solution rocks! I was able to extend our iSCSI volume, finally.
