Topic: Move from 9 to 10.1 RAID question

[alanh]

Hi,
I had a server (server only) running for a few years on SME Server 9 with 2 x 1TB drives in RAID1, on the contrib Raid Status panel it showed 2 raid names as expected as attached image (raid 2).  I backed up the server config to smeserver.tgz and installed 2 new identical 2TB disks - installed SME 10.1 and restored config file. after installing raid status config I go into it and get 3 raid names (attached image raid 3).  Just wondering why this is so and what I may have done wrong.
I built another 10.1 last week to test, different computer but same install, selected RAID1 etc and that one is ok with 2 raid names.
I'm really not sure what to do now , and wondering if I need to do it all over again?
Any help appreciated...

ao the answer is you have an EFI system hence one raid for system, one for boot and one for EFI.
