[Bug 1902855] Re: two identical disks are only offered as a multipath device

[Matthias Klose]

see also LP: #1871611, failing the install with disabled multipath.

You find several more reports about multipath being problematic, and
usually you can work around the issue by disabling multipath support on
boot by not loading the module. However multipath is hard wired into the
installer.

I'll remove the disk for now for the installation, however this is not
possible when you can't access the disks, or when they are soldered.
having two SSDs in notebooks is not uncommon.

Bug description:
  two identical SSDs are only offered as a multipath device in the
  server installer, not as single devices. The install succeeds, however
  the following boot falls back to the initramfs because the volume
  group cannot be found. Same hardware configuration as in LP: #1902845.

  blacklisting the dm_multipath module on the installer boot,  shows the
  two disks, however the installer later fails because the multipath and
  multipathd commands fail.
