I have an Adaptec RAID-Controller and created an RAID-1(Mirroring) succesfully.
Now I have installed Ubuntu Server 12.04.3. When I type fdisk -l I get this output:
bf@fileserver:~$ sudo fdisk -l

The 80 GB HDD is for the System
The 1000.2 GB HDD should be for my data. But I'm a bit confused becauser there are listed two 1000.2 GB HDDs, due the Hardware RAID shoudln't there be only one HDD vissible to the OS? (I have two 1000.2 GB HDDs in an Raid-1 Array)
dmraid gives me
bf@fileserver:~$ sudo dmraid -r
/dev/sdb: ddf1, ".ddf1_disks", GROUP, ok, 1953253376 sectors, data@ 0
/dev/sda: ddf1, ".ddf1_disks", GROUP, ok, 1953253376 sectors, data@ 0
so It seems to be ok? But how do I partitionate this disks and which one should I mount(sdb or sda?)
Hope you can help me
thx
Florian
