Red Hat Bugzilla – Bug 231370
installer doesn't remove legacy hardware RAID tattooing on drives
Last modified: 2008-05-06 15:19:42 EDT
Description of problem:
Currently anaconda can't properly recognize an existing software RAID-1 root
partition for upgrading if the drives were ever been used in a hardware RAID
(such as Promise RAID using motherboard support). The nodmraid option has to be
used to prevent dmraid from getting confused by the residual tattooing left on
the drives by their previous use in a hardware RAID-1. The Fedora installer
should provide some method to remove this residual tattooing so that future
upgrades can be done without resorting to nodmraid.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. On a machine with motherboard RAID support and two sata drives, configure the
two drives in the BIOS as a RAID-1 mirror. After the drives have been
synchronized as a RAID-1 mirror, disable the motherboard RAID in the BIOS so the
drives are treated as separate devices again.
2.Boot the FC5 installer with the nodmraid option, create RAID-1 partitions in
DiskDruid using software raid partitions on each drive and install FC5.
3.Boot the FC6 installer without the nodmraid option.
The FC6 installer can't find the FC5 installation on the software RAID-1
partition unless nodmraid is used.
The FC6 installer ought to be bright enough to recognize that although dmraid
sees the legacy tattooing left on the drives from the hardware raid usage that
these no longer are being used that way. An option should be presented to the
user that would allow the residual hardware RAID tattoing to be removed from
these drives (since it is no longer used).
