Description of problem:
RAID 1 devices that are missing some components (say, if I took out one of the
two replicas of my / filesystem to install the new beta on it) are not properly
detected. The installers reports the partitions as RAID devices, but not as
members of any RAID device.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Create a RAID1 device out of two partitions.
2.Create a filesystem on it.
3.raidsetfaulty and raidhotremove one of the partitions
4.Create a new RAID1 device using the partition that had been removed, with the
other device marked as failed-disk.
5.Create a filesystem on it.
6.Start the installer.
Actual Results: It reports both partitions as having type RAID type, but
they're not members of any RAID device. I can't create a RAID device out of any
single one of them while preserving the contents either. I can't ask the
installer to install on any of them as if it just contained an ext3 filesystem,
without formatting the entire partition and losing the RAID bits. (I can do this
by changing the partition type with fdisk, though; phew!).
Expected Results: It should detect RAID arrays containing failed-disks. It
would be nice to be able to create RAID devices like that too, but this is a
separate bug report. It would be nice to be able to tell the installer to use
the existing ext3 filesystem without having to format it or tweak its RAID type.
This is on the second Limbo. I haven't tried any of this with the first Limbo
Dupe of a combination of earlier bug reports about using/creation of degraded
