Turn on journaling in 10.11 on software RAID

I use Pro Tools on my Mac Pro for music creation. The User Guide recommends that journaling is enabled for better performance.

I've recently done a clean install of El Capitan on my boot up drive and so I selected OS X Extended Journaled as the volume format.

I have two other volumes on the Mac which were formatted prior to installing El Capitan. One appears to be journaled (when I select it in the Disk Utility list and click the info tab). The other volume is a software RAID which appears non- journaled. When I have selected it in the disk utility, the option to enable journaling is greyed out in the file menu.

So, how can I turn on journaling in El Capitan on a software RAID?

I don't want to reformat the RAID as I understand that software RAID creation is no longer available via Disk Utility

Thanks for any help.

Mac Pro, OS X Mavericks (10.9.5)

What happens when you are booted into Recovery—will it allow you to enable journaling?

Hi leroydouglas,

No, even if I start up in Recovery, Disk Utility shows a greyed out "enable journaling" in the file menu.

One thing I've just noticed is that in the Disk Utility window, the icon for the software RAID is aligned under/with all the PHYSICAL DRIVES rather than appearing as a VOLUME. If I select, for instance, my boot drive and hit the info tab, the resultant info shows "Journaling = No", whereas if I select the associated volume it shows "Journaling = Yes".

I believe that you can only journal a volume and not a drive, but I would have expected my software RAID to be considered a volume rather than a disk.

Any thoughts?
