Description Bernhard Wiedemann 2013-01-15 18:00:05 UTC

openQA.o.o tests found that
installation hangs always while installing grub2
onto a logical volume

ps ax shows a large number of udevd --daemon 
processes and some /etc/nothing -q -- char-major-6-0

as if something tried to modprobe the driver for /dev/lp0

LVM installation was broken for a long time by bug 790724,
so it is unclear, when this really broke

Installation killed by os-prober

This happens when grub2-mkconfig runs os-prober. I do not see char-major-6-0, but otherwise similar symptoms. Scrrenshot with list of processes attached.

Where can I read more about /etc/nothing?

Comment 2 Andrei Borzenkov 2013-01-15 20:18:55 UTC

OK, at least in this case it is clear. "blkid" returns type of partition "LVM2_member", which os-prober does not understand and tries to mount using "LVM2_member" as filesystem type which in turn results in kernel trying to autoload this module.

/usr/lib/os-prober/50mounted-tests has to ignore partition of type "LVM2_member".

Comment 3 Steffen Winterfeldt 2013-01-16 13:47:15 UTC

/etc/nothing is obsolete. It came alive accidentally as a result of a code
cleanup. I've removed all traces of it now.

Please test again with linuxrc 4.1.4.
