 Posted: Fri May 15, 2009 5:19 am Post subject: Annoying problem with cannot open root device /unkno[SOLVED] |
 |
|
my dell inspiron 6000 gets the following error:
| Code: | | VFS: Cannot open root device "0301" or unknown-block(3,1) |
I seached, and it looks like that error is tied to a missing device driver for the drive
relevant section of lspci -nqn says:
| Code: | | 00:1f.2 IDE interface [0101]: Intel Corporation 82801FBM (ICH6M) SATA Controller [8086:2653] (rev 03) |
http://kmuto.jp/debian/hcl/index.rhtmlx says that is:
| Code: | | 80862653 Yes Intel Corporation 82801FBM (ICH6M) SATA Controller ahci,ata_piix v2.6.25- |
grepping .config gives:
| Code: | root@sysresccd /root % cat /mnt/gentoo/boot/config-2.6.29-zen1-12may09-1| grep -i ahci
CONFIG_SATA_AHCI=y
root@sysresccd /root % cat /mnt/gentoo/boot/config-2.6.29-zen1-12may09-1| grep -i piix
CONFIG_BLK_DEV_PIIX=y
CONFIG_ATA_PIIX=y
CONFIG_PATA_MPIIX=y
CONFIG_PATA_OLDPIIX=y
# CONFIG_I2C_PIIX4 is not set |
i'm using xfs
| Code: | root@sysresccd /root % cat /mnt/gentoo/boot/config-2.6.29-zen1-12may09-1| grep XFS
CONFIG_XFS_FS=y
CONFIG_XFS_QUOTA=y
CONFIG_XFS_POSIX_ACL=y
CONFIG_XFS_RT=y
CONFIG_XFS_DEBUG=y
# CONFIG_VXFS_FS is not set |
i can't figure out why my machine won't boot. help?

I have the same probelm pretty much, cant give much details now as im posting from work, and at home currently installing the 32bit version instead of the 64bit where I had this problem(Ill go home and try 64bit again).
I had this problem with the vanilla-sources-2.6.29.3 kernel on an amd64 system.
I have the JMicron SATA controller, its freaking easy to find in the kernel configuration thing, If I dont enable this in 32bit I get the same message.. its quite weird that im having this now  |

any progress on it?
I can get older kernels (*.26 ara) to toad, but then those have a conflict with lvm

it could also mean that you are trying to mount from a non existant disk as your root partition.
And people "used" to fail with a message more like
| Code: | | VFS: Cannot open root device "hda1" or unknown-block(0,0) |
and not an "0301" harddisk.
So, recheck your root= (or realroot) from grub.conf for a valid harddisk (uhci or newest PIIX ata named drives as sd for example) |

ok, i've tried various combinations of "root", "realroot", "real_root" and "real-root" paired with "sda1", "hda1", "/dev/sda1" and "/dev/hda1"
relevant section of grub looks like:
| Code: | title gentoo
root (hd0,1)
kernel /vmlinuz root=/dev/hda1 |
/boot is on a usb key, hda has /root, 2 swap partitions (one for tux on ice), and a lvm partition

As krinn said, newer kernels use sd names for that driver, not hd. You need to update your grub.conf. You say you already tried that, but without knowing the exact combinations you tried, we need to start over.
Please post the exact error message, including at least 6 lines of context before the panic. Post the kernel command line that you used for that failure scenario. |

The real_root= parameter only works if the kernel was built using genkernel.
Your kernel is configured with both the old IDE drivers and the new sata/pata drivers.
CONFIG_IDE=y should not be selected.
The following should be selected if you have a CD/DVD drive
# CONFIG_BLK_DEV_SR is not set
# CONFIG_CHR_DEV_SG is not set
Change /dev/hd... to /dev/sd... on the kernel command line and in /etc/fstab |

The last two look like scsi options so i set them as modules.
made other changes as indicated.
am getting the same kind of error

CONFIG_BLK_DEV_SD=m should be CONFIG_BLK_DEV_SD=y It is need to access the disk.
The sata/pata drivers use the SCSI support routines. CONFIG_BLK_DEV_SR and CONFIG_CHR_DEV_SG can be modules but CONFIG_BLK_DEV_SD must be built into the kernel because it is needed to load the modules. |

/boot is on a usb key

usb key are also name sd? by linux kernel (also handle as scsi if you prefer) and considering you are booting with a grub hd(0,1) i suppose your usb key is handle as 1st harddisk.
This mean you're "real" harddisk would be the 2nd, so it will be sdb.
But instead of guessing like you've done, while you're in grub you should push e key (edit) so grub might help you find out where is your root partition, by doing hd( then push TAB it will list visible harddisk and partition...
if you're sure your root is on the 1st partition of your harddisk, you may just try /dev/sdb1 as root |

The good news is that solved it. Thanks to you and everyo9ne else who assisted.
The bad news is not only am I stil having baselayout /lvm issues, but i'm getting kernel oops re: xfs. i'm gonna post the i8nfo on the latter in the zen support thread momentarly.
