However, now Anaconda complains about partitions required.

[CentOS] Centos 6 / Kickstart Using degraded mdadm RAID1
I'm trying to install a bunch of C6 involving initially degraded mdadm RAID 1 Anaconda refuses to let me create a RAID 1 array with only one member. Based on some reading, it seems that I should be able to use kickstart with the PRE scripts to do this. However, after trying for a couple of hours, it doesn't seem that anaconda will allow it, it just boots the created arrays. At best I end up with a list of softraid partitions instead. Am I trying the impossible or has anybody done this before and can point to a resource how on this can be done? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Potentially by dropping into a shell to do parts of it (eg build the raid array degreaded, then use the GUI to install onto that). If so, manually do an install and then look at /root/anaconda-ks.cfg to see what file that built out. It might provide the hints you need. -- rgds Stephen ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Unfortunately the anaconda-ks.cfg in that config gave very little clue what was done, there are just 4 relevant lines which look like this #raid / --fstype=ext4 --level=1 --device=md0 raid.253001 raid.253065 Nothing usual, and make sense since I created the md arrays and ananconda simply used them without assembling them itself. The problem is I can't figure how to kickstart to the point where the mds arrays are created successfully. The command works in shell but somehow in the kickstart process, the created array disappears after ananconda does the Examining storage device thing. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
