Title: Adding raid partitions
Post by: Alex Schaft on January 31, 2006, 01:36:38 PM

Hi,

I'm experimenting with raid on a test setup. I installed sme7pre1 on one hard drive, then added a second identical drive, partitioned, and added as follows:

mdadm /dev/md1 -a /dev/sdb1
mdadm /dev/md2 -a /dev/sdb2

Which went fine. However, after rebooting, both arrays ran degraded again, and re-adding them caused them to sync up again. How do I make the partitions stay in the arrays?

Hi,

I think all I need to do, is set my partition type to Linux raid autodetect (fd).

Can someone confirm this for me?

Alex

Just a note here on Raid

It is very important, that you only use one IDE disk per IDE bus. Not only would two disks ruin the performance, but the failure of a disk often guarantees the failure of the bus, and therefore the failure of all disks on that bus.
