RAID1 restore to only one disk?

[hikohiro]

I've made an image of entire disk of firmware RAID1 and then restore it back.
Then I check the /proc/mdstat, found that the RAID is resyncing.

The restore to RAID1 just writes to one disk!!
Is it normal case? or I made any mistake?

BTW,
I've encountered the rd.md.uuid problem on first boot after restore.
I just delete the options of "RD_MD_UUID=xxx:xxx:xxx...", and it works.
OS is CentOS 6.6

Are you doing this from the IFL boot disk?

If so, is the RAID drive showing up in the list of drives to restore to in IFL (such as /dev/mdX)?

If it only restored to one drive as you say, that sounds like you restored to an individual drive, such as /dev/sda, /dev/sdb, etc, rather than to a RAID drive such as /dev/mdX

Also, if you're not using the latest version of IFL (currently 2.97a), it would be worth updating to it, since just doing that could resolve the problem. Registered users can update to the latest version at no cost at the Product Download page here:
