[lfs-support] GPT Partitioned Drive on BIOS Station, Unable to Mount Root
I've installed LFS on a GPT SSD on a BIOS station with the help of jhalfs and the kernel, started with grub-2, fails to boot completely as it can't find the root filesystem. The familiar VFS Unable to mount root fs, Panic. I've built LFS since 2003 or was it 2002 and I've seen this message quite a few times. However this time, I'm unable to get it to boot anything. I've confirmed that the kernel works fine as I still have my old LFS build on another drive on the same station. I have /boot on sdf2 and / on sdf3 Model: ATA Crucial_CT120M50 (scsi) Disk /dev/sdf: 120GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End SizeFile system Name Flags 1 1049kB 1000MB 999MB primary bios_grub 2 1000MB 5000MB 3999MB ext3primary 3 5000MB 118GB 113GB xfs primary boot 4 118GB 120GB 2034MB linux-swap(v1) primary /dev/sdf2: UUID=a6960224-5c35-43e9-920b-7d9e1225ab26 SEC_TYPE=ext2 TYPE=ext3 PARTLABEL=primary PARTUUID=96326d8d-fe5e-4c2d-acd5-6b9380441476 /dev/sdf3: UUID=7440b882-aecb-4e4a-8ecb-24d7a31dc9f9 TYPE=xfs PARTLABEL=primary PARTUUID=6335e500-106b-4a33-9e54-709a33681ba6 /dev/sdf4: UUID=8128605c-690e-49d3-bbaa-5214f21c8c89 TYPE=swap PARTLABEL=primary PARTUUID=a9e95be4-db76-4c4d-9f02-5b4f22c796b1 /dev/sdf1: PARTLABEL=primary PARTUUID=bb8dc183-06bc-4500-a205-afd753de1802 When I boot the SSD, I set this drive in the BIOS as the first drive, so as to be able to boot from it. I refer to the drive as hd0 in grub console. It is still however referred to sdf when linux boots. I've confirmed this in initrd. linux (hd0,gpt2)/linux-3.10 root=/dev/sdf3 ..and I've also tried: linux (hd0,gpt2)/linux-3.10 root=PARTUUID=6335e500-106b-4a33-9e54-709a33681ba6 I've also tried initrd, which dumps me right in its simple shell. I'm there able to mount /dev/sdf3 to /.root/, but not successful in running switch_root .root /sbin/init. I can post all that is happening in initrd, but I think first I'll try to get this out and see if there's anything I forgot. I've expected LFS to be bootable after running jhalfs and fixing fstab. # Begin /etc/fstab #UUID=7440b882-aecb-4e4a-8ecb-24d7a31dc9f9 / xfs defaults 00 #UUID=8128605c-690e-49d3-bbaa-5214f21c8c89 swap swap pri=10 0 /dev/sdf3 / xfs defaults0 0 /dev/sdf4 swapswappri=1 0 0 proc /procproc nosuid,noexec,nodev 0 0 sysfs /sys sysfsnosuid,noexec,nodev 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 tmpfs /run tmpfsdefaults0 0 devtmpfs /dev devtmpfs mode=0755,nosuid0 0 #UUID=a6960224-5c35-43e9-920b-7d9e1225ab26 /boot ext3 defaults0 0 /dev/sdf2 /boot ext3defaults0 0 # End /etc/fstab I'm on a Tyan Thunder n3600B (S2927-E) (S2927A2NRF-E) station and I've compiled SATA chipset and XFS filesystem support into the kernel: CONFIG_SATA_NV=y CONFIG_XFS_FS=y I'm quite stuck on this one and I'm open to anything.

Re: [lfs-support] GPT Partitioned Drive on BIOS Station, Unable to Mount Root
The one thing I noticed was your grub bios boot partition is over 900mb mine on my arch Linux install is 32kb. Did you make a separate bios boot partion or did you include it into your boot partition?

Yeah, sdf1 is that big, because I had no idea what GPT was until a few days ago. I figured that I wouldn't need a BIOS Boot Partition, if you are referring to an ESP (EFI System Partition), because I use a BIOS and I understood it like I didn't need one. It's only on UEFI systems that an ESP is needed, as far as I understand. I made a bios_grub partition on sdf1, so that grub-2 could install its magic in there. Then I made /boot on sdf2 and / on sdf3. I have swap on sdf4. Then I ran grub-install on /dev/sdf which completed successfully. -- Esben Stien is b0ef@e s a http://www. s tn m irc://irc. b - i . e/%23contact sip:b0ef@ e e jid:b0ef@n n -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
Re: [lfs-support] GPT Partitioned Drive on BIOS Station, Unable to Mount Root
One of the great things about hanging around on LFS mail-lists is that you often get to learn about new hardware (in this case Tyan stuff). Specifically, about its existance.

So, let me get this straight. When you put the new kernel into the old LFS, it boots like a charm but when you put that same kernel into the new LFS, it fails? Also, the old LFS is on a normal HDD, and the new LFS is on a SSD, right? If yes, then the problem seems to be either triggered by the difference in the housing drives or by differences in the userland, correct? Maybe you could try that trick in booting USBs where you configure the kernel to wait a bit before trying to boot the userland.
