Hi,
I upgraded my kernel and while doing this, I also changed away from old ide to scsi. Therefor I used NeddySeagoon's guid https://forums.gentoo.org/viewtopic-p-6362608.html#6362608 My box runs without any signes of problem to the user, but somehow /dev looks strange.

The default install is to use udev and a tmpfs /dev that automatically populates /dev with only relevant devices... Is this how you set up /dev ?
I also heard of some strange stuff related to having legacy EIDE drivers installed in the kernel as modules or even regular with newer versions of udev...
How is your machine set up now?

Hi,
I have udev installed and it shows up in rc-update show as udev-postmount | default.
| Quote: | | sys-fs/udev-151-r4 USE="extras old-hd-rules -devfs-compat (-selinux) -test" |
I also Use hal and hald | default.
| Quote: | | sys-apps/hal-0.5.14-r2 USE="X acpi consolekit crypt -apm -debug -dell -disk-partition -doc -laptop -policykit (-selinux)" |
| Quote: | | Linux claudius 2.6.34-gentoo-r6 #2 SMP Tue Oct 19 20:21:56 CEST 2010 i686 Pentium III (Coppermine) GenuineIntel GNU/Linux |
The kernel config can be found here: http://gentoo.pastebin.ca/1967756
Oh and it is not the box from the sig. |

probable cause of excess obsoleted devices.
should not need -devfs-compat |

| If you have a relatively-recent kernel that has devtmpfs, and you have it enabled, you can go as far as to empty the /dev folder that's on the hard drive. |

Changing to -old-hd-rules in udev did not change the behavier. Also trying to attach a usb device doesn't seem to be posible. | Quote: | usb 1-2: new full speed USB device using uhci_hcd and address 2

butdoes not show any sde stuff and | Code: | | mount /dev/sde1 /mnt/usb/ |

Any more ideas? |

shows???
what version of udev? check your work against the udev guide Is udev-postmount in the default run level? If baselayout2/openrc is udev in sysinit run level?
| Code: | | zgrep -i CONFIG_SYSFS_DEPRECATED_V2 /proc/config.gz |
should yield | Quote: | | # CONFIG_SYSFS_DEPRECATED_V2 is not set |
consider: boot rescue cd, mount gentoo partitions, | Code: | mv /mnt/gentoo/dev /mnt/gentoo/dev.old
mkdir /dev
reboot |
be patient, then log in, follow the strange directions: | Quote: |
-----------------------------------------------------
Your system seems to be missing critical device files
in /dev ! Although you may be running udev or devfs,
the root partition is missing these required files !
To rectify this situation, please do the following:
mkdir /mnt/fixit
mount --bind / /mnt/fixit
cp -a /dev/* /mnt/fixit/dev/
umount /mnt/fixit
rmdir /mnt/fixit
You may refer to these instructions at /etc/issue.
If you previously had an issue file, it has been
backed up at /etc/issue.devfix. Once you've fixed
your system, you will have to restore your old issue
file in order to get rid of this warning.
Thanks for using Gentoo !

Edited after trying the mv. I use gpm, made this easy. And again to add sysfs check and udev stuff. Thanks Neddy.

hitachi,
It looks like you have a static /dev
Is udev started?

@ NeddySeagoon
now that you ask, I am not longer sure about that.
| Code: | | /etc/init.d/udev start |
| Quote: | * The udev init-script is written for baselayout-2!
* Please do not use it with baselayout-1!. |
baselayout-2 is not stable, jet. So I am sure I am using baslayout-1.

hitachi,
You are using baselayout1, so you don't need that script.
udev should be started for you at boot. Watch the kernel messages. You should see something about mounting /dev then later, populating /dev/ ... waiting for uevents to be processed.
If you don't have shmfs in your kernel, you can't have /dev/ in shmfs do df, does one line read something like | Code: | | shm 4092876 100 4092776 1% /dev/shm |
The numbers are not important.
Without shmfs, your /dev will be on your hard drive. it can still be managed by udev but if it was populated with static entries beforehand, they will still be there. With udev and shmfs, udevs /dev/ is mounted over the top of anything else called /dev, so if you have both a static /dev, and a udev /dev/ the static /dev will be hidden.
You can boot a CD, mount your root on /mnt/gentoo, then look in /mnt/gentoo/dev to see if you have a static /dev. You need at most three entries, /dev/null, /dev/console and I forget the other but even these are not needed with later udev as it makes these nodes for you.

Hey NeddySeagoon,
you solved my problem!
File systems --->
Pseudo filesystems --->
Virtual memory file system support (former shm fs)
It was disabled and now it is enabled. Everything is fine, now. Thanks! |
