Description Manfred Spraul 2000-10-06 04:12:20 EDT
I tried to upgrade Redhat 6.2 to RedHat 7.0, and the installer crashed in
readFstab, line 1028 (in fstab.py) while parsing a raid disk in /etc/fstab

I printed a few variables with the debugger, and

	raidByDev: {} 
	raidList: {}

were both empty, thus raidByDev[int(...)] crashed.
It was scanning /dev/md0 when it crashed

Comment 1 Manfred Spraul 2000-10-06 04:51:08 EDT
I also checked the partition type of /dev/hda3 & /dev/hdb1:

both partition types are 0x83, not 0xfd.
Perhaps it's a problem with line 21 in raid.py?

-	if type != _balkan.RAID: continue
+	if type != _balkan.RAID and type != _balkan.EXT2: continue

I always assumed that 0xfd is only required for autostarting raid devices, all
other raid devices can use 0x83?

Comment 2 Michael Fulbright 2000-10-06 14:07:49 EDT
All RAID devices are assumed to be type 0xfd.

You can probably complete your upgrade by just commenting out the line in
/etc/fstab containing the RAID device, unless it contains files the upgrade will
touch. Then uncomment it after you reboot after the upgrade.
