 Posted: Sat Feb 10, 2007 2:50 am Post subject: Checking root filesystem...[CLOSED] |
 |
|
i just finish the installation but when i boot i get this:
| Code: |
checking root filesystem...
ext2fs_check_if_mount: No such file or directory while determining whether /dev/ROOT is mounted.
fsck.ext3: No such file or directory while trying to open /dev/ROOT
/dev/ROOT:
The superblock could not be read or does describe a correct ext2 file system. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate suberblock:
e2fsck -b 8193 <device>
* Filesystem couldn't be fixed :( [!!]
Give root password for maintenance
(or type Control-D to continue):
(none)~# |
is this belong to incorrect partitioning of my hd?

/dev/ROOT is just a placeholder in the default /etc/fstab.
You need to edit this file so it matches the way your system is actually set up. For example, replace /dev/ROOT with /dev/hda3 |

Read the Gentoo Handbook section on creating /etc/fstab
Quickly,
| Code: |
#nano -w /etc/fstab
|
You must have skipped that step in the install. So, you'll have to rerun the LiveCD, mount your drives to correct mount points per the Handbook instructions, and then chroot in. From there, run the nano command and, providing everthing else was done properly, you can exit your chroot environment, reboot the box, and things should start up fine. Provided everything else was done properly.
You'll have a skeleton fstab. Fill it in with the correct values for your drive setup. |

sorry for late reply, but i wanted to check that i solved the problem.
know after reboot i login as root and created a user account sccessfully but i fail to
| Code: | | emerge mirrorselect |
is that because the host name and the routes not configerd the right way? 
thanks |

No, that wouldn't have anything to do with why you're not able to mount your filesystem. In fact, there's no step in the handbook that requires you to emerge mirrorselect.
As I pointed out in my previous post, you need to follow the Handbook to mount your root filesystem. For example, if my / was /dev/hda3, I'd fire up the LiveCD. At the prompt, I'd do this:
| Code: |
#mount /dev/hda3 /mnt/gentoo
#nano -w /mnt/gentoo/etc/fstab
|
That will enable you to alter your fstab (FileSystem TABle). You must have missed that step. Where it says
| Code: |
dev/ROOT / ext3 noatimes 0 0
|
I'd replace with my real root device:
| Code: |
/dev/hda3 / ext3 noatimes 0 0
|
Does that make a bit better sense? |

acculy, i am following the quick installation quide and i refer to the hand book only if needed.

#nano -w /mnt/gentoo/etc/fstab
|
i have finished this, and i altered the file and now i am in the finalizing installation stage:
i also could add now user account:
| Code: | mybox ~ # adduser -g users -G lp,wheel,audio,cdrom,portage,cron -m a****
mybox ~ # passwd a****
New UNIX password: Set a****'s password
Retype new UNIX password: Type a****'s password again
passwd: password updated successfully |
which i wasn't able to do it before chanhing the value in "fstab"
now i have failed to use "emerge"
how could i proceed with the installation then?
ahmed, |

I would recommend you still use the Handbook, especially if you're new to installing. The Quick Install guide follows a different process and, IMO, is meant for users who have done a full Handbook-based install and understand all the steps they need to make in an installation. The Quick Install assumes you know what you're doing and how to fix things if they go wrong. As far as mirrorselect is concerned, it is already included in the LiveCD, and can be used prior to entering your chroot environment, like this:
| Code: |
#mirrorselect -i -o >> /mnt/gentoo/etc/make.conf
#mirrorselect -i -r -o >> /mnt/gentoo/etc/make.conf
|
Now . . . can you paste in your emerge error so we can see what is happening? |

Hi,
this is what i got when i use:

You can only use the mirrorselect commands as I posted them if you are working under the liveCD and have mounted your root partition to /mnt/gentoo and have either unpacked a stage3 tarball or have a full system already untarred on the / partition.
The emerge error is that there is no route to the host. First off, is your networking setup properly?
What happens if you do this:
You should see something like this:
| Code: |
#ping -c 3 www.gentoo.org
PING www.gentoo.org (66.219.59.46) 56(84) bytes of data.
64 bytes from kiwi.gentoo.org (66.219.59.46): icmp_seq=1 ttl=51 time=41.8 ms
64 bytes from kiwi.gentoo.org (66.219.59.46): icmp_seq=2 ttl=51 time=50.7 ms

rtt min/avg/max/mdev = 41.864/45.270/50.714/3.893 ms
|
Additionally, it seems that ftp address may be wrong. I went to cudlug.cudenver.edu and found the proper listing here:
http://cudlug.cudenver.edu/gentoo/distfiles/
I presume ftp would operate at the same address, since that address is not recognized by ftp on my box. |

sorry if im repeating anything that has already been said.
but just for a personal checklist.
can you ping things? (use command in post above)
are you chrooted?
(in the guide this code is used to chroot, did you use this?
| Code: | chroot /mnt/gentoo /bin/bash
env-update
source /etc/profile
export PS1="(chroot) $PS1" |
)
if you did then before hand did you copy over your resolv.conf file?
(using the command
| Code: | | cp -L /etc/resolv.conf /mnt/gentoo/etc/resolv.conf |
and after you edited your /etc/fstab file properly?
yet again, sorry for repeating any information if i did.
just trying to help. |

it's me again,
well, when i used:
| Code: | ping -c 3 www.gentoo.org
PING www.gentoo.org (66.219.59.46) 56(84) bytes of date.

| Quote: | are you chrooted?
(in the guide this code is used to chroot, did you use this?
Code:
chroot /mnt/gentoo /bin/bash
env-update
source /etc/profile
export PS1="(chroot) $PS1" |
this is the code i use when chrooted, and in the same seq.
Code Listing 2.16: Chroot
| Code: | livecd usr # cd /
livecd / # mount -t proc proc /mnt/gentoo/proc
livecd / # cp -L /etc/resolv.conf /mnt/gentoo/etc/
livecd / # chroot /mnt/gentoo /bin/bash
livecd / # env-update && source /etc/profile
>>> Regenerating /etc/ld.so.cache... |
| Code: | mybox ~ # route -n
Kernel IP routing table

0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 |
but, before we go farther, can i ask one question:
when i used the following code:
| Code: | livecd etc # cd conf.d
livecd conf.d # echo 'config_eth0=( "192.168.1.10/24" )' >> net
livecd conf.d # echo 'routes_eth0=( "default via 192.168.1.1" )' >> net
livecd conf.d # rc-update add net.eth0 default
(If you compiled your network card driver as a module,
add it to /etc/modules.autoload.d/kernel-2.6)
livecd conf.d # echo r8169 >> /etc/modules.autoload.d/kernel-2.6
(If you want to reconnect via ssh after you have rebooted your new box:)
livecd conf.d # rc-update add sshd default |
will this configure the network as static ip address, right? and the ip is 192.168.1.10?
what if i want to use DHCP, won,t this solve the problem? |

Not a good idea. | Quick guide explicitely wrote: | | The Quick install guide covers the Gentoo install process in a non-verbose manner. Its purpose is to allow users to perform a stage3 install in no time. Users should already have prior experience with installing Gentoo Linux if they want to follow this guide. |
The Handbook has all the information you need to set up networking. |
