Description stephen hemminger 2006-01-06 03:15:34 UTC

installkernel has problems with either RAID and/or current 2.6 kernels.

Doing a "make install" runs /sbin/installkernel and then I get the attached output.  Surprisingly, the install runs fine.

This system has three Raid partitions (root, tmp, and home). So the
perl script is probably getting confused.

Stephen, this is *not* a bugzilla bug - this component is ONLY for bugs in bugzilla itsself. So, if you can't report a bug, report it here ;-)

Please move this bugreport to Product "SUSE Linux X.Y" (choose your version) and a matching component, then set the bugreport back to ASSIGNED.

Tsts. jack?

Comment 3 Joachim Plack 2006-01-10 14:11:12 UTC

Well the problem comes from 'udevinfo' giving no output. Dunno nothing about that tool.
Will change that Tools.pm handles that gracefully.

Code in question:
    open (OUT, "udevinfo -q name -p /block/$udev |") || die "Cannot run udevinfo";
    my $dev = <OUT>;
    close OUT;
    chomp ($dev);

Comment 4 Joachim Plack 2006-01-10 14:22:42 UTC

ok submitted to svn.
Kay can you give me advice what might have gone wrong?.
May be the output 'no record for '/block/sda/uevent' in database' from up there 
can give you a hint

Comment 5 Kay Sievers 2006-01-10 16:11:52 UTC

You can't call udevinfo for the device _attribute_ "uevent", it expects a _real_ device. Udevinfo does only print stuff that custom rules have stored in the udev database. "Default" device names are the same as the sysfs names. What information does the perl code expect from udevinfo?

Comment 6 Joachim Plack 2006-01-16 14:23:22 UTC

the code path that call udevinfo is actually a little bit hacky and could need
some major rewrite. But errors are handled ok for now. so -> fixed
