I have asked my question about the RAID driver in, so I don't want to crosspost that
question, but the next steps are hopefully corret for this forum:

How on earth should I partition a SATA RAID1 set to be able to use nss ?

My previous server had a SMART Controller, so I created two virtual
disks and was fine off. The ML 115 just allows to mirror the SATA drives
in the Controller BIOS, and so I think I need to use EVMS. EVMS expects
to find hardware to set the volumes on top, but I am confused: should I
first create the EVMS volumes and mirror them later, or mirror first and
use the resulting virtual drive for EVMS.

maybe someone can sine some light on that

Thanks in advance
