it seems like I keep running into a wall.
The present raid array...well let me do an fdisk -l:

kk...the ide drives; hda and hdc...3 partitions 3 arrays md0 1 and 2
cat /proc/mdstat shows it's acting as it should.
when I boot the system up, it sees the drive connect thru usb and calls
it sda (for what reason I don't know. I partitioned it to the same specs
as the 2 ide drives as per the bottom of fdisk -l.
Now, trying to go by:
http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/admin-guide/
5.9.8.2 Creating RAID Arrays
they state the following:
Next, it is necessary to create the /etc/raidtab file. This file is
responsible for the proper configuration of all RAID arrays on your
system. The file format (which is documented in the raidtab(5) man page)
is relatively straightforward. Here is an example /etc/raidtab entry for
a RAID 1 array:
ummm...1.)I think this is part of the old raidtools thang...not mdadm
but I am not sure.
2.) there is no man raidtab on this box which is a "everything"
install..
so considering this..lol I'm lost.
kk, right now...I just formatted all the partitions and (I should have
done this before ) I am checking for bad blocks. If it finds some I'll
just redo it or whatever I have to do. At one point I was able to
mdadm /dev/md0 1 & 2 --add sda1 2 &3 and
cat /proc/mdstat would show sda1 2 &3 as in the arrays but then they
would not populate.
I can't remember but I think I gave them mount points but wait, I was
having a hard time finding the proper syntax for that as well
anyway, after rebooting...it was all gone.
this ain't nice
thx
