/dev/disk-by-id could be problematic. it only showing disks that have been formatted.
For example, I've just created a node with 3 disks and on Anaconda I chose only the first disk. After the node installation and reboot, I see on /dev/disk/by-id only the DM, and the DVD, not the two unformatted disks (which can be seen using lsscsi command). Anaconda, however, does see the disks, details etc...
That's not what I know. Might be something with udev or some filtering, but certainly I was not aware it's related to formatting.
Unfortnately not all disks provide an (stable?) ID. After formatting (at least with 'pvcreate'), the UUID from the LVM-header is also used for creating /dev/disk/by-id/... symlinks to the disk/partition. I'm not so sure about getting the symlinks after formatting with a filesystem though. Related to this: https://github.com/heketi/heketi/issues/1371 Niels
