Description Michal Jaegermann 2007-05-25 23:29:04 UTC 
Description of problem:

On a test system I have a drive which has partition from
/dev/sda1 to /dev/sda15.  Unfortunately anaconda creates only
/dev/sda1 to /dev/sda14 nodes and when booting "rescue" 20070525
images, and an installation which happens to use /dev/sda15,
it fails to mount a corresponding partition producing an error.

In a similar manner /dev/sdb1 to /dev/sdb14 and /dev/sdc1 to /dev/sdc14
are also created for two other disks which happen to actually use
much smaller numbers of partitions so there you never bump into
that issue.

BTW - this is not an issue with libata.ignore_hpa=1 from bug 241288.
When booted to a shell prompt it is possible to do

  mknod /dev/sda15
  lvm vgchange -a y

(as this partition happens to be used by an lvm volume) and after
that corresponding volume "magically" appears in /dev and its
logicals can be mounted without any further troubles.

Version-Release number of selected component (if applicable):
anaconda from 20070525 images (it does not show its version)

How reproducible:
always

Fix the missing /dev/sda15 device

There can be only 15 of scsi partitions right now, thanks to libata.. but there
was a small error... range(1,15) didn't create the 15th device.

Additionaly and for sure, check ensure device exists when used to normal mount
and label testing.

patch cleanup

Patch cleanup, better error checking and reporting (to log).
