I have just completed hadrware installation of my new RAID server which will run with Ubuntu Server OS. I have installed Ubuntu Server OS and everything run seemingly without problems.
However, I have few questions, I can not find answer to anywhere. I hope, I can find them here.
Server Info:
- Ubuntu Server 14.04.2 TLS
- Adaptec RAID 72405
- Ubuntu Server is installed on separate SATA HDD, which is not part of the Adaptec RAID field
- RAID Level 6 used
Questions:
Adaptec offers Ubuntu drivers for the RAID 72405 controller. Do I need to install them? Apparently, I can access the RAID folder. Is the Ubuntu driver needed only if the OS itself is installed on the RAID field?
I consider populating 50% of HDD bays now, and remaining 50% later, when needed. Will this be possible even if no Adaptec drivers are installed? After rebuilding the RAID 6, will I need to additionally increase Ubuntu partitions? Can the RAID 6 rebuild be done with all the data present, and the data won't be damaged after the rebuild?
How to correctly initialize the hardware RAID folder? Currently it it as /dev/sda on the server.
Thanks in advance.
