Re: Successfully boot from a floppy on a GPT partitioned 2.18TB system
Poe Chen [EMAIL PROTECTED] writes: The system needs to use GPT because any system that has more than 2TB will need GPT. Regular PC (msdos label in parted) partition table won't be able to handle that. And it looks like that Mac needs GPT too Right. have you tested how well GRUB can handle big filesystems, or don't you have any? About the (hd0,0) to (hd0,1), it means that if you have (hd0,0) in regular PC partition table, it becomes (hd0,1) in GPT format. Not sure why, but that's how I boot it since I can't find anything under (hd0,0) once I switch to GPT. Oh, I see. That's something that should be fixed I think. I will have a look at it, but it won't happen this month. -- Marco ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel

Like I said, I'm using GRUB2 to floppy boot a 2.1TB machine (the main barrier with large file system is 2TB) and t looks like it's working fine. However, I do have problems installing GRUB2 on the RAID system. I'll describe it in another post. Software RAID is not supported yet, if that is the question.

I thought that's how GPT partition works =) Well, I am not sure. :-) -- Marco ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
Re: Problem installing GRUB2 on a 2.1TB system
Poe Chen [EMAIL PROTECTED] writes: I'm the same guy who has successfully floppy boot GRUB2 on a 2.1TB system. =) Here are the problems that I've encountered to get GRUB2 installed onto my system running CentOS 4.2 with latest updates. -grub-probefs can't detect the file system on my server. Here are the system info: [EMAIL PROTECTED] ~]# df -k Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda2 4032124 2810480 1016816 74% / /dev/sda1 101086 11576 84291 13% /boot none516768 0516768 0% /dev/shm /dev/sda42300710112 1547872 2182292912 1% /home And here is the result: [EMAIL PROTECTED] ~]# grub-probefs -v /dev/sda grub-probefs: info: changing current directory to /dev grub-probefs: info: changing current directory to cpu grub-probefs: info: changing current directory to mapper grub-probefs: info: changing current directory to input grub-probefs: info: changing current directory to net grub-probefs: info: changing current directory to shm grub-probefs: info: changing current directory to pts cannot find a GRUB device for /dev/sda. What kind of filesystem do you use? Can you show the output of `mount'? Please be *very* careful with installing on GPT. The only way to use GRUB with GPT is by using a floppy. This is because it does not have a bootsector. The intended way of booting such system is by using EFI. Unfortunately I don't have such system available and GRUB 2 is not changed so it can deal with EFI. Also see my other email regarding this issue: http://lists.gnu.org/archive/html/grub-devel/2005-11/msg00163.html Any ideas and suggestions regarding this problem are welcome. I expect more people will run into this problem. Thanks, Marco ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
