HP Microserver G8 loosing RAID0 array after shutdown

Hi,

I purchases two G8's recently to run Ceph Storage. My config is:

1x SSD for OS (I added this drive instead of DVD)

4x HDDs for data (not in RAID)

The problem is that I am not able to boot from the additional SSD unless I create RAID0 on this drive. But when I do, the array is lost after shutting the system down. This has happened twice already.

To recover, I just create a RAID0 array again on the SSD and the system boots. But this is getting quite anonying.

Any thoughs?

BTW, the best would be if I am able to boot from the SSD without creating RAID, but not sure if this is possible.

Thanks Jiri
