We were bashing our head after adding tonnes of disc to our iSCSI array and this brilliant. Thanks again. Worked a Treat. de VK3IVY aka Ivy =) Thank you so much.

I took a bit of a calculated risk building a DIY RAID, and thanks to your post I have no worries about any aspect of the array now. I am running a RocketRaid 3540, I expanded to 7.5TB but was unable to find anywhere or anyone who had successfully expanded using this card under MAC OS X. even Highpoint said it was unsupported under OS X... so after the 4 days it took to expand the drive i am very grateful to find your post! Thanks again! Jon Scott, Thanks so much for this!

I was having problema resizing partitions after removing a Linux install. I don't have RAID but this worked just fine. Thanks for this! I was having problema resizing

This is terribly useful and should be posted all over the net as a useful and easy way to migrate up a raid 5 system. @todd - a day late and a dollar short, but I got the same response from show gpt Todd when I added the disk slice. /dev/disk7s4. The 's4" part made it go wonky and return the whole volume info with no gpt info. Then I re read the instructions and did a rectal cranial inversion and got it working. Well, theoretically... diskutil is still thinking as I write this. IT did, however save me from having to move 3 TB around my system. Thanks Scott. Well done. -James Diskutil is still modifying the partition map as I write this… but I just have to say “thanks.” This is terribly useful and should be posted all over the net as a useful and easy way to migrate up a raid 5 system.

I use a PromiseRAID with an xserve. I bought the half-loaded version with around 4TB in it. Once I migrated in new drives, the PromiseRAID saw the added drives. However, I had to fully eject, unplug, wait 60 seconds, and then plug back in and mount for the OS to see that the RAID was bigger. This did not, however, fix the problem that you have fixed here. I was still unable to expand the partition via CL or the disk utility UI. I have an Apple Tech rep who could not tell me what the problem is. In fact kept telling me that the Apple documentation and diskutil function should work. I was extremely frustrated because the Promise system was officially supported by Apple and was the biggest reason I did not go with a cheaper system. I will be forwarding this fix to my rep with the hopes something like this will be included in a future Mac OS Server update. Hopefully you get some credit considering you are the only person on the entire inter-tubes with a fix... Once again, thank you. Nick. I can’t thank you enough for this.

It's a guess as I don't know enough about it. Looks like it is formatted for Apple Partition Map instead of GUD. If that's the reason, guess I'll have to erase, format at GUD and copy back from the mirror. Todd I think I just discovered my problem. It’s a guess as I don’t know enough about it.

However, today in trying your instructions with a RAID 6 volume it doesn't come back with any GPT information. So, I can't destroy anything. Another words... when doing step 3 above this is what is reported... start size index contents 0 19531243520 That's it. No PRI GPT info... Disk Warrior shows no errors on the drive. Disk First Aid verifies it fine as well. It was expanded from 6TB to 10TB. It's an Areca 1680 card. Have any ideas what I can do? Thanks, Todd Hi Scott -

These instructions posted by Scott are excellent! I highly recommend it over anything else to quickly fix the problem as described.
