I've partitioned a server disk fairly heavily, and I want to RAID1 it.
I see on the 'Net that there's such a thing as "partitionable RAID
arrays". But I also read that this isn't such a good idea. Seems
pretty good to me: build an array of unpartitioned drives, and slice
it up. Is there really a downside to this?
And I see talk of versions of the superblock, that 1.0 is better than
0.9, etc. Does it really make any difference? Should I even consider
the 1.1 at the beginning of the disk? It's claimed there's something
in the mdadm config file that selects the version, but I don't see
anything about it (lenny)...
And am I correct in believing that the kernel RAID-assembly-at-boot
applies only when the partition type is 0xfd? And that mdadm is the
only way to have arrays of unpartitioned drives? And that mdadm
completely ignores (or never sees) udev's /dev and uses the kernel
names?
