Description Gabriel Ramirez 2013-05-20 16:41:42 EDT
Description of problem:
I tried to install Fedora 19 Beta TC2 in two existing raid1 (linux kernel software raid) via kickstart:

so after anaconda started I switched to a terminal  an typed:

cat /proc/mdstat
Personalities : [raid0] [raid1] [raid6] [raid5] [raid4]  [raid10] [linear]
unused devices : <none>

mdadm --assemble /dev/md0 /dev/vda2 /dev/vdb2
mdadm: /dev/md0 has been  started with two drives.

mdadm --assemble /dev/md1 /dev/vda3 /dev/vdb3
mdadm: /dev/md1 has been  started with two drives.

cat /proc/mdstat
Personalities : [raid0] [raid1] [raid6] [raid5] [raid4]  [raid10] [linear]
md1 : active raid1 vda3[0] vdb3[1]
          12067751 blocks super 1.2 [2/2] [UU]

md0 : active raid1 vda2[0] vdb2[1]
          511936 blocks super 1.2 [2/2] [UU]

unused devices : <none>

ls /dev/md*
/dev/md0 /dev/md1 /dev/md1p1 /dev/md1p2

after that switched back to anaconda via alt-F7

and tried to refresh the disks to show the raids partitions and anaconda showed the error

thanks, 

Gabriel

Please try it again, but skip the part where you go to the shell and manually activate your md arrays. Thanks.

if in the kickstart have the following:

raid /boot --level=1 --noformat --device=md1 /dev/vda3 /dev/vdb3
raid / --level=1 --noformat --device=md2 /dev/vda4 /dev/vdb4
raid /var/lib/lh/syslinux --level=1 --noformat --device=md0 /dev/vda2 /dev/vdb2
raid swap --level=1 --noformat --device=md3 /dev/vda5 /dev/vdb5

the installer shows in text mode:

Members may not be specified for prexisting device

Pane is dead

cat /proc/mdstat

> (In reply to David Lehman from comment #13)

if in the kickstart have the following (the md devices from the previous run):

raid /boot --level=1 --noformat --device=md125
raid / --level=1 --noformat --device=md126
raid /var/lib/lh/syslinux --level=1 --noformat --device=md127
raid swap --level=1 --noformat --device=md124

the installer start in graphical mode but shows in the left corner

No disks selected 

in a virtual terminal cat /proc/mdstat
Personalities : [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] [linear]
unused devices: <none>

after a while the installer shows:

An unknown error ocurred and the log shows:
