[SOLVED] Replace sda with sdb (raid1)
by circus78 from LinuxQuestions.org on (#4W5YV)
Hi,
I have a system with two RAID1 devices (md0 for / partition, md1 for swap).
First disk (sda) failed.
If I replace sda with a new disk (blank), system is unable to boot.
From BIOS, I have no way to tell "boot from THIS disk", I can only choice between PXE, Sata controller, CD ROM or USB device.
If I remove sda, and leave only the second disk, system boots fine (and the only recognized drive is sda).
I wondering if I could simply physically replace sdb with sda, and then add new blank disk as the "new" sdb.
Any suggestion?
