Hi, I try to install Jessie with a soft RAID6 of four disks, 1 TB each. The idea is to use the complete disk for RAID and then only on top separate swap and root.
The installation worked fine on one machine, but for some reason, grub does not install on the fourth disk. It turns out, that the fourth disk is GPT, while the others are DOS (= MBR, right?). Also, the fourth disks only partition is of type "Linux RAID", while the partitions of the other three disks are "Linux raid autodetect". On a second machine, supposed to be identical, grub-install failed on all disks, but I could not yet check, whether GPT is the culprit, too. Questions: AFAIK, I don't need GPT for such small disks, right? Is there an easy and safe way to change the disk from GPT to DOS/MBR? Who did set up the disks in that heterogenous way? d-i? Why? Thanks in advance! PS: Last time I had a similar install was with etch or lenny, IIRC. Despite the issue I face, d-i made so much of progress in that area. Wonderful!
