FWIW, there is an example of an LVM device that reports as an ATARI partition in this Rook
issue:
https://github.com/rook/rook/issues/2047. I don't think this matters a lot
because it is still on LVM, but I don't want to ignore it if it is a useful data
point. As Sebastian aptly mentioned, I think that Rook starting to use raw mode instead of
lvm mode for OSDs is likely why this issue is popping up now when it hadn't been
earlier.
To speak to Sage's options:
(1) From what I have been able to find out, support for ATARI/AHDI disks isn't
something that can be disabled in the kernel the same way a kernel module can. It seems
that the kernel is either built with the support enabled or it isn't. This means we
just have to suggest that users avoid distros built with the ATARI support.
(2) I think this would be the most ideal option, but I'm not sure anyone really wants
to do this. XD
(3) I'm not sure how much of this we could avoid in bluestore. This seems like it
might not be super feasible to me, but I'm certainly no expert.
As for Rook, I am hoping to do some investigating to see if `blkid` will tell us about
atari partitions where `lsblk` does not.
I wonder if it might be just as good an option to have `ceph-volume` check for ATARI
partitions when we request it provision a raw device and bail out if it detects one.
