I have a SR2500 server with the active RAID backplane. This server has been running flawlessly with 4x1TB discs for 3 years. I need some more space, so I have changed to 2TB drives.
The problem I keep running into is that the RAID array keeps getting dropped. When I reboot, the RAID controller says it has found a foreign configuration.
When I clear the configuration and setup the RAID array completely from scratch, it happens again. (I start a disk format in Centos, 2 hours later I get an error that /dev/sdb is missing, when I reboot the RAID BIOS wants to import a foreign configuration again).
Could the problem be that I used plain disks (Samsung Spinpoint F4 EcoGreen 2 TB, 5400) instead of verified compatible disks?
Or could it just be a bad disk?
I've seen the other thread about foreign configuration import problems, but that seemed to be a one-time event. That is why I created a new thread. Any help greatly appreciated!
First I'd suggest you update the RAID firmware, because you seem to be running a quite old version.
When the RAID BIOS wants to import a foreign configuration, do you still have your existing configuration and have access to your VD? How did you configure the RAID?
Yes it's always recommended to use HDDs in the tested list.
