I have a pegasus 2R6 (20TB) set up wit 3 logical drives. (12TB) is used for backup, (4TB) is used for Timemachine, and (4TB) is for temp storage. All in all it works fine. I have found out that the first chosen disk sizes are not optimal for me. Can I 'shrink' the temp disk and then afterwards let the Timemachine 'expand' into the now available space?

And still keep my data

Just for info I have a separate Pegasus 2 R4 just for my live data

I have an iMac 27"-5K and macOS 10.14.6

Kind regards

Hi Palle,

We need to verify the subsystem report to help you on this, so could you get the report using Promise utility and create a web support case at where you can attach the report.

Steps to save the subsystem report:

- Open promise utility
- Click subsystem information icon on the top of the Promise Utility window
- Click the lock symbol on the left bottom corner of the screen to unlock the utility
- Click on save service report button to save the subsystem report.

Thank you,


Promise Team

Hi and thanks for the question

frankly I dont recall ... the system works fine as such, I have however modified the setup so now I have 3 boxes: a Pegasus 3R4 16TB for live data, a Pegasus 2R4 for Timemachine onlyand the Pegasus 2R6 for backup of the Live data, and as general storage.

They are now placed in a separate room connected via a long Corning TB3 cable and daisychained via  an TB3/TB2 adapter.

kind regards
