Doc Text:
.The USB CD-ROM drive is not available as an installation source in Anaconda Installation fails when the USB CD-ROM drive is the source for it and the Kickstart `ignoredisk --only-use=` command is specified. In this case, Anaconda cannot find and use this source disk. To work around this problem, use the `harddrive --partition=sdX --dir=/` command to install from USB CD-ROM drive. As a result, the installation does not fail.

Description of problem:

This is a regression compared to RHEL8.2 DVD.
When installing a system using the RHEL8.3 DVD connected to a USB port and a kickstart specifies "ignoredisk --only-use=sda" (where "sda" is the hard disk), the following error is seen and unattended installation is aborted:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
anaconda.log:14:30:23,312 WRN kickstart: Command cdrom will be parsed in DBus module.
anaconda.log:14:30:32,091 ERR payload.manager: PayloadError: Found no CD-ROM
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

This seems due to having the DVD seen as "/dev/sdX" (e.g. /dev/sdb) hence being ignored/blacklisted.

The issue doesn't happen with RHEL8.2. With RHEL8.2, the anaconda.log message about "cdrom" stanza is not present, there is this instead:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
anaconda.log:14:52:04,797 DBG payload: Setting up cdrom install device
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Configure a VM to present the DVD as a USB CDROM

-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
    <disk type='file' device='cdrom'>
      <driver name='qemu' type='raw'/>
      <source file='[...]/rhel-8.3-x86_64-dvd.iso'/>
      <target dev='sdd' bus='usb'/>
      <boot order='1'/>
      <address type='usb' bus='0' port='4'/>
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

2. Boot on the DVD and load the kickstart in attachment (ks.cfg in logs archive)

ks.cfg excerpt:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
ignoredisk --only-use=sda
clearpart --initlabel --drives=sda
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

Actual results:

Unattended installation doesn't happen

Expected results:

Unattended installation happens

As a workaround you can comment out the "cdrom" kickstart command and use the "harddrive" command instead:

harddrive --partition=sdX --dir=/

(change sdX to the name of the USB device, for example sdb).

Can you please confirm this workaround works for you?

Comment 3 Renaud Métrich 2021-01-19 13:27:55 UTC
Perfect, that works!

i think it's good to delete with cdrom, and we also need to see why is it error with this environment.
