Hi.  I'm a relative Linux neophyte who has been using a Raspberry Pi as a slave torrent processor.  To do this, I had a toy RAID arry set up with a 7-port USB hub and 6 flashdrives in a RAID 5 configuration.  It worked amazingly well.  (I had been tired of my USB laptop hard drives burning out after a few months of hard use.)

Anyway, I recently replaced the Raspberry with an Orange Pi Plus 2 using Raspbian.  I can't get RAID processing to work.

mdadm is present and current, but when I go to create an array, it complains:  mdadm:  RUN_ARRAY failed:  Invalid argument

I read somewhere that this may be RAID support missing from the kernel.  If this is true, how do I obtain the source, made the required changes, and recomile it?  Also, why has this been left out?

Any help would be appreciated.  Thanks in advance.

You have to recompile kernel or compile kernel modules

Try Debian by @loboris has enabled RAID support by default (but the project is probably abandoned),
you can also check armbian by @igorpec (project is still alive)

Thank-you darqoq.  I wasn't really planning to change OS but armbian looks really good and handles my miniature RAID quite well.  I'm a "convert".
