Summary: Unknown filesystem error with non-first partition of disk Project: GNU GRUB Submitted by: sreich Submitted on: Tue 21 Jul 2009 06:40:50 PM GMT Category: Filesystem Severity: Major Priority: 5 - Normal Item Group: Software Error Status: None Privacy: Public Assigned to: None Originator Name: Originator Email: Open/Closed: Open Discussion Lock: Any Release: SVN Reproducibility: Every Time Planned Release: _______________________________________________________ Details: Hello, I have been fiddling with the GRUB2 for a while now, thinking they were mostly problems with what I was doing...I have covered many bases, however. First of all, I have been formatting my drives and converting them to Ext4..my 250 GB External(USB) was what I started with. I wanted to create an install of Linux on this, so as to serve as an up-to-date sort of LiveCD, thusly -- I wanted GRUB2 on it, so it can boot by itself. So I created a new partition table on it, then created Partition #1 (235) GB then created Partition #2 (15 GB). Both are Ext4, and the first is completely blank (I didn't add a thing to it), the second is where that Linux install is located, I installed Linux on it without installing GRUB at all... I then booted into my normal install and installed GRUB2 onto it(first by chrooting into it, according to the link to the wiki via the IRC channel). After restarting, and selecting (via BIOS), to boot to that External drive, it came up with an error saying "GRUB Rescue \n Unknown Filesystem". I even unplugged my other hard disks to be fully certain that it was not a different hard disk. I then installed GRUB2 from SVN, hoping that it would resolve my problems and I installed it to the correct drive(even wiping the /boot/grub before hand), same error. Well, I was experimenting with the rescue mode -- excellent work on this by the way, I'm glad I can try and debug the problem instead of it just saying there was some error in Stage 1 , etc... So I typed 'ls' at the rescue prompt. This listed my drives and their partitions, I only had 1 drive connected at that moment, so it would only find the External.. I typed 'set' and prefix=(hd0,2)/boot/grub and root=(hd0,2) Well this looked fine, as the second partition is the only one that matters..so I tried to dig further... I tried 'ls (hd0,2)/', but it comes up with the same error I have been getting... I then tried 'ls (hd0,1)/' and listed was 'lost+found" (the ext-created folder). Well this means it had no problem listing the first partition... I even put some files on that partition and it read them fine.. I did not try putting GRUB2 on this first partition, as I would really rather not (I'm anal like that and like to have what I use the most categorized). Also tried, was re-creating the partition table and remaking the partitions...I also tried recreating the second partition as ext3...same problem. I think that's everything..let me know if you need more info, as I *really* *really* want this fixed quickly as I want to convert everything to ext4, get stuff setup, and get back to coding... Thanks. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?27069> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/ _______________________________________________ Bug-grub mailing list Bug-grub@gnu.org http://lists.gnu.org/mailman/listinfo/bug-grub
