Dear All,

I have 3TBx2 drives and want to install debian on them as RAID1. i know rest of the thing. i have been creating software raid on less then 2TB drives for years but now since HD size is growing as per the market trend i need to go with it.

Both drives are detected in the manual partition menu of Debian Jessi setup process. when i try to create bigger partition it give me error like this  partition length of sectors  xxxxxxxx exceeds the msdos-partition-table-imposed maximum of xxxxxxx

i know this is happening because of MBR limitation. therefore i need your help.

can you guys please guide me how can i create bigger partition while installing Debian.  Easiest way would be i install smaller drive and create bigger partition with gdisk . but i do not want this i only have 3TB drives and want to install Debian on top of it and also want to make Debian to boot from the drives. i know the RAID part but missing part is How to create GPT partition during installation.

Any help would be highly appreciated.

Thanks, Yousuf

https://www.gnu.org/software/grub/manual/grub.html#GPT states how to do this. Basically, you need to partition your drives with a GPT, then create a tiny (~1MB) partition called the BIOS Boot Partition. Details are in the above link for how to mark the partition as the BIOS Boot Partition. You can then install grub to this partition.
