The title says it all. I have a new Pegasus32 R6 which is configured as raid5. I would like to change this to raid6 but am unable to find any instructions to help me.

 

Help!

and thank you.

Hi Andrew,

The simplest and fastest way is from the CLI.

Assuming you have a mac, the CLI can be accessed by opening a terminal then entering 'promiseutil' without the quotes.

The commands are ...

array -a del -d 0
array -a add -p 1~6 -l "raid=6"

After this you will have to use the macOS Disk Utility to put an HFS+ filesystem on the LUN.

Be advised that you should not put an APFS filesystem on storage with spinning disks, it will get very slow as the filesystem gets filled.
