Any *helpful* suggestions?Oh, Helpful suggestions! damon@dam-main:~$ cat /proc/mdstat Personalities : [raid1] [raid6] [raid5] [raid4] md0 : active raid1 hdg6[0] hdh6[1] 76613888 blocks [2/2] [UU]So, since I have mdadm installed and I am running raid1, the cat results in listing raid6 as a possible "Personality" I would say it works just fine. YMMV. Try it.
man mdadm (but only in part, a very small part -l, --level=Set raid level. When used with --create, options are: linear, raid0, 0, stripe, raid1, 1, mirror, raid4, 4, raid5, 5, raid6, 6, raid10, 10, multipath,
mp, faulty. Obviously some of these are synonymous.
When used with --build, only linear, stripe, raid0, 0,
raid1, multipath, mp, and faulty are valid.
Not yet supported with --grow.
so, again, it seems to be supported.
