Expanding Storage via expanding RAID Array

[cswizard]

I have a DL-380 Gen6 SFF. Currently, two 145GB SAS drives in a RAID 1 array (Array A) as the boot volume and two 450GB SAS drives in a RAID 1 array (Array B) for add-on storage. I want to add 4 more 450GB SAS drives but I'd like them to extend the existing storage on Array B such that all 6 450's are in one RAID array. I would also like to convert the RAID 1 array to RAID 5.

HP says this is possible by adding the 4 new drives to the array, then selecting migration to RAID 5 once they're added. My question then becomes (assuming that this works), how do I utilize this additional storage in Proxmox.

Happy to provide any additional information needed to determine a solution.

From doing some looking around, it seems that all I might need to do is a pvresize after the RAID array is expanded. Can anyone confirm?

Hi,
yes if you use the raid as lvm-storage.

Perfect. The RAID array is set up as LVM-based storage.
