[mythtv-users] Software RAID disappearing on reboot...

[Jon Larson]

I know I created the FD "autodetect RAID" type on the partitions, but I
didn't create the mdadm.conf or do anything to any init scripts. 
 
Can you tell me what you needed to do to add the "mdadm stuff in my init
scripts"? What do you mean by that?

I had a similar problem, here are the things I did wrong: 

a) I didn't create a partition on the drives of the correct "Autodetect RAID
type", was setting up the RAID on the raw disks instead
b) I didn't create the /etc/mdadm.conf
c) I didn't have the mdadm stuff in my init scripts....

My suggestions, setup the raid, check out the contents of /proc/mdstat after
everything is all synched up, reboot... If the raid volume is there, you
should be golden to proceed with LVM. Otherwise, try starting it manually
with mdadm... If that doesn't work, post the output of your /proc/mdstat to
the list and any applicable dmesg stuff...

I'm using mdadm to create a raid1 array on knoppmyth R5C7. I thought that I
had overcome all the problems since the raid array seemed to work fine--I
even configured LVM on top of it. But when I rebooted the whole thing just
disappeared, as if mdadm forgot that it ever existed. Please note, I'm not
trying to boot of the raid array (not yet), just get it up and running so
that I can transfer my knoppmyth distrobution over to it... Can anyone
suggest what I might be doing wrong?
