Oh man, what a madness!!!!
Well, after some years with FreeNAS - and now a short excursion with NAS4Free - it was time to begin some new thing :). So I decided to install OMV and look what's on the other side of the world ;). Backup of my ZFS-Raid and then a short switch to OMV. Installation pretty easy except for the grub-installation. I really don't understand it, but my installation-disk was sdc and grub absolutely want to be installed on sda!!! No way to switch to sdc. Well, now I boot with the good old Lilo
After that I want to build a raid5 and the anger began!!!!!! No disk was seen in the menu. After some searching in the old forum I now know that OMV needs disks without any partitions or file systems. Ok, but how to reach this with Linux??? It has taken 2,5 hours to solve this problem!!!! It was not enought to wipe the whole disks, no it was necessary to penetrate the disks with the dd-command. Oh man, which normal person could this know????
Improvement proposal: Could anybody insert a command to "format" any disks in a way, that OMV is able to recognize this as disks for raid-configuration???
