I wish you the best (similar setup here and bad experience with adaptec raid cards) :-( As per the 4 TiB issue. I just have reviewed the wikipedia article about MBR and forgot the limit of 2 TiB for a "bootable" partition.

Which Apaptec model, specifically? Some of the Adaptec SATA cards are fakeraid. I want to know if your card is fakeraid or real RAID. That may have bearing on this issue. > I wish you the best (similar setup here and bad experience with adaptec > raid cards) :-( > > As per the 4 TiB issue.

I always create a small /boot of about 100MB at the start of the disk and stick the bootloader in the MBR. Every BIOS can handle bootstrapping such a setup. I thought the OP originally said he has a separate small /boot, so I'm still not sure what his exact issue is. Thus what I'm trying to nail down exactly which Adaptec HBA he's got. -- Stan -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

Being a Supermicro server, I doubt it's a "fakeraid" card O:-) OTOH, a fakeraid won't see a big disk of 4 TiB, it would detect/treat each drive separately. >> I wish you the best (similar setup here and bad experience with adaptec >> raid cards) :-( >> >> As per the 4 TiB issue.

Yes, that tends to be the better approach. Either "ext2" or "ext3" are the recommended filesystems for GRUB. > I thought the OP originally said he has a separate small /boot, so I'm > still not sure what his exact issue is.

I would try, at first place, to make the required partitions from a Gparted LiveCD (System Rescue or similar) before installing the system to see if that helps the installer.

Hi just picked up a 51645 adaptec - having some problems with the gui can't login and if I try and boot of the adaptec lun it crashed grub - magic failed.
