What am I missing when creating a raid 1 configuration. I added a new
disk to the system (/dev/sda) and put the old disk as /dev/sdb (these
are SATA drives)
I built a new system on /dev/sda (/ = /dev/sda6, /var = /dev/sda5,
/usr=/dev/sda6, /boot=/dev/sda1, and swap=/dev/sda3) and I left
roughly 300 GB for /home at /dev/sda7.
I did the following:
fdisk and set /dev/sda7 to type fd (/dev/sda7 2569
48641 370081341 fd Linux raid autodetect)
mdadm --create /dev/md7 --level=1 --raid-devices=2 /dev/sda7 missing
(I'm planning to add /dev/sdb7 upon successful creation)
mkfs -V -t ext3 /dev/md7
e2label /dev/sdb2 /home1
e2label /dev/md7 /home
created a simple entry in /etc/mdadm.conf with "MAILADDR root"
next copied all my user data from /dev/sdb2 (my former /home
partition) to /dev/md7. This worked fine.
Then when I rebooted the system, /dev/md7 was gone and the system
mounted /dev/sda7 as /home
Where did I go wrong?
Thanks, Jeff
I found my answer, or at least part of my answer. I ended up creating
an additional line in /etc/mdadm.conf that said "ARRAY /dev/md7
devices=/dev/sda7"
On a previously installed system (FC6) I only had the single line
"MAILADDR" and everything else was identified properly. One big
difference was all the partitions were mirrored including /boot and /
and the boot line specified "root=/dev/md6" Is it because the root
partition was a raid that the the raid partitions were automatically
assembled previously?
Thanks, Jeff
