Hi, 
We currently have a 2 node on Always ON Availability group with a cloud witness. Recently, we found the need to resize the data file disk. This 2 nodes are SQL Server on Azure VM.

Find below our current situation

1st Resize on the secondary node (read-only) 
Resizing first on the secondary node – we noticed that the disk type changed from Basic to Dynamic mode and having seen some documentation on internet — Aligning dynamic disks – BlackCat Reasearch Facility (lokna.no) we thought of been cautious of having the disk in dynamic mode. 
As a result of the above, we did not proceed to resizing the the production until we are sure.

Question 
Is it save to proceed with disk in dynamic mode? 
What if we proceed and the primary is still on Basic mode, is it OK to have the disk type of primary node as Basic and the disk type of secondary as Dynamic?

Thanks
