Description hvv 2003-02-09 03:38:46 EST
Description of problem:

Currently anaconda enforces RAID1 arrays to have at least 2 members. This is
unreasonable since it disallows to e.g. install system only on 1 hdd, and then
add the 2nd to the system and turn it into the raid1 arrays' member (by editing
/etc/raidtab, adding partitions of the 2nd hdd as failed-disk, then remaking
raid arrays with mkraid and then hotadd'ing partitions of the 2nd HDD to the
raid arrays).
I had to hack installer and burn cusom disk1 to be able to make RAID1 arrays
with only 1 member in order to be able to install system on only one hdd.

FYI mandrake installer does allow to have only 1 member of raid1 array (and did
allow this for agaes AFAIK).

This isn't something we're planning to support currently. 
Comment 2 hvv 2003-02-11 05:09:51 EST
Why then close this bug with WONTFIX?
May be set a resolution to DEFFERED in order not to forget to implement
it later?

We do not plan to support this mode of RAID creation.
