Hello all,

I have the following configuration that results in an exception being thrown ("pre-mount actions failed") during boot after entering the LUKS password for the RAID array, which seems to assemble just fine in the prior step. I can also assemble this array, luksOpen, and mount just fine manually. See bellow and attached photo (sorry):

>            %base-file-systems)))

I'm also unable to reconfigure the system unless I already have the array mounted and luksOpened, so perhaps I'm doing this all wrong?

Thank you,

-Nick
