Description QingLong 2006-11-07 11:21:41 UTC
Description of problem:
There is a partitionable array md_d0 (raid1) with 9 partitions
which should be available during system boot up.
But the raidautorun of nash does not start it properly
and the system fails to start up with stock initrd.
Manual intervention is necessary: one has to add mdadm.static to the initrd
filesystem and insert proper (mdadm) command line into the init nash script
to revive the system.

Version-Release number of selected component (if applicable):
4.2.15-1

How reproducible:
100%

Steps to Reproduce:
1. Create partitionable array with a handfull of partitions in it.
2. Use those partitions in the system layout.
3. Add appropriate `raidautorun' line to init nash script (within initrd)
4. Reboot the system and see if raidautorun starts that partitionable array.

Actual results:
raidautorun does not create correct partition layout and correspondent block
devices.

Expected results:
Partitionable array should be started with correct partition layout
and correspondent block devices (per partition).

Additional info:
1. It looks like madadm itself has the same bug:
   without explicit command line option (-ap9)
   it does not create correct number of devices for partitions
   within a partitionable array.
2. I have tried to update the system to fc5 and fc6 but failed,
   as the upgrade scripts failed to startup correct filesystem layout.
   So it looks like the problem is still there.
3. The necessity of such layout (partitionable array with 9 partitoions in it)
   has been caused by the (%*^#%&!) 15 partitions restriction in fdisk
   (added there by redhat for a reason I still refuse to understand).
   And, btw, fc6 rescue-cd and cd1 do not contain sfdisk which could be used
   as a (manual) workaround over that stupid restriction.
   (sorry, I despise druid and similar tools).

This report targets the FC3 or FC4 products, which have now been EOL'd.

Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?

Thanks.

Comment 2 QingLong 2007-01-22 10:30:57 UTC
The problem is still there, at least in FC5.
Haven't tried it in FC6 yet, as the machine runs in production mode
(frequent changes are deprecated).

   To my regret I cannot upgrade to a later Fedora release
as since Fedora 7 PATA disks are always treated as SCSI disks
and SCSI disks cannot contain more than 15 partitions,
while I do have more than twenty of them.
It seems I should have to switch to some other Linux distribution.
