Subject: [PATCH] cdrom_id: use the old MMC fallback
|
|
|
|
https://bugzilla.redhat.com/show_bug.cgi?id=1038015
|
|
The problem seems to be that the your virtual DVD is emulating a really
|
|
old DVD device, and doing it kind of strangely.
|
|
|
|
> dracut:# /lib/udev/cdrom_id --debug /dev/sr0
|
|
> probing: '/dev/sr0'
|
|
> INQUIRY: [IMM ][Virtual CD/DVD ][0316]
|
|
> GET CONFIGURATION failed with SK=5h/ASC=24h/ACQ=00h
|
|
|
|
So your virtual drive rejects the GET CONFIGURATION command as illegal.
|
|
|
|
Other pre-MMC2 drives that don't accept this command usually return the
|
|
error
|
|
SK=5h,ASC=20h (invalid/unsupported command code), in which case cdrom_id
|
|
tries an older method, and then ID_CDROM_MEDIA_TRACK_COUNT_DATA gets set
|
|
and all the /dev/disk/by-label (etc) links get set up.
|
|
|
|
The virtual drive returns the error SK=5h,ASC=24h (invalid field in
|
|
Command Descriptor Block), which cdrom_id doesn't handle, so it gives up
|
|
and the links never get made.
|
|
|
|
The ideal solution would be to make the IMM to emulate a device that's
|
|
less than 15 years old, but I'm not going to hold my breath waiting for
|
|
that.
|
|
|
|
So probably cdrom_id should also use the old MMC fallback when the error
|
|
is SK=5h,ASC=24h, and then all of this would work as expected.
