Subject: [Bug 218866] Extra /dev/sd.. entries for a fake raid when more than 15 partitions
Date: Sat, 22 Jun 2024 07:52:19 +0000	[thread overview]

--- Comment #11 from Marc Debruyne (marc_debruyne@telenet.be) ---
(In reply to Phillip Susi from comment #9)
> This is no bug.  Fake raids are, well, fake.  The kernel sees both
> individual disks and since they are mirror images of each other, both have
> the same partitions on them.
> 
> The dmraid utility can be used to recognize the fake raid metadata and
> configure the kernel device mapper to access the raid, and with the -Z
> switch, it will remove the partitions from the underlying individual disks
> from the kernel's view.

dmraid is not used; mdadm is used
