Bug 432362

I got the same thing, but I wrote down the stacktrace (as I was not able to
upload it to a remote site).

The problem occurs when a RaidSet is present as can be seen in the stacktrace (I
copied another stacktrace and filled it out).

I got a fakeraid controller, ICH9R, but I guess the bug is not chipset specific.  

The stacktrace:
anaconda 11.4.0.28 exception report
Traceback (most recent call first):
  File "/usr/lib/anaconda/isys.py", line 494, in hardDriveDict
    ret[item] = dict[item]['description']
  File "/usr/lib/anaconda/partedUtils.py", line 841, in driveList
    drives = isys.hardDriveDict().keys()
  File "/usr/lib/anaconda/partedUtils.py", line 615, in startDmRaid
    (self.driveList(), ))

Digging around a little (and maybe I'm missing something), but I don't see that
the description set in hardDriveDict is used anywhere.  I changed it like:

-        ret[item] = dict[item]['description']
+       try:
+           ret[item] = dict[item]['description']
+       except:
+           ret[item] = "no description"

and anaconda appeared to find the dmraid drives okay.

The description is copied in partedUtils.py drivesByName, but I don't see that
it is called anywhere.  If the description really isn't used, maybe just drop
trying to copy it?

Anaconda crash traceback

I've run on the same problem today when trying to install Fedora 9 Beta. I
tried installing from both full install DVD and Live DVD.

Fixed in git

Traceback in anaconda-11.4.0.61-1

Jeremy,

I'm still getting the traceback (attached). I've tested with the released
rawhide 20080328 snaphot and also reproduced with Fedora 9 Beta Live after
updating anacona via yum to version 11.4.0.61-1 that's available in rawhide as
of now.

The change in git adds an empty description.  However, the problem isn't a
missing description; it is that a RaidSet object doesn't have __getitem__ but
hardDriveDict() in isys.py tries to access it that way.  Either the RaidSet
object (I believe from python-pyblock) needs to be updated to add __getitem__ or
isys.py needs to be changed to not try to access it.

Confirmed, this still happens in rawhide 04/01.  Going to get some attention on
it since we have a box in the office that can reproduce.

Anaconda debug log

Changing the subject to reflect what the bug actually is.  This should be fixed
with the work Peter Jones did last night and was built into anaconda this
morning.  It missed rawhide though, so will try later.

This is fixed.  dmraid installs now boot.
