 |
|
hi all,
i wanted to get rid of all of the device node i had under dev.
thatswhy i emerged udev, deactivated the device tarball option in conf.d/rc and moved my dev entries to another dir hoping that they will be reassigned by udev.
After reboot on "cheking root filesystem" i now get the message "no such file or directory while trying to open /dev/hda1 the superblock could not be read"
and i have the only possibility to reboot or start in mainntenance mode Control-D. After doing maintenance I only have readonly access to my formerly hda1, but no hda1 entry in dev so I could not move the device nodes back. When I start with gentoo livecd it gives me a full list of entries in /mnt/gentoo/dev when i mount /dev/hda1 to it so everythings seems to be fine - until reboot :-/
I also restored setting in rc "RC_DEVICE_TARBALL="yes"" without luck.
Kernel: 2.6.11-gentoo-r9
What else can I do? |

If you want read/write, you can do "mount / -o rw,remount". To remount read only (if you need to do a hard reboot), run the same thing but with "ro" instead of "rw".
What was there before the problem ? devfs ? Check you have RC_DEVICES="udev" (or auto) in /etc/conf.d/rc. Also do you have some nodes in /dev when in maintenance mode, or nothing at all ?
If you run these commands, do the disk nodes appear (if it complains that sysfs is already mounted, it's not a problem, just run the other commands) ?
| Code: | mount -t sysfs none /sys
mount -t tmpfs none /dev
udevstart |
If they do not, does your drive appear in /sys/block ? |

Setting the entry RC_DEVICES="udev" solved my problem. Now /dev/hda1 appears again and boot processed successfully.
But I'm almost sure that this entry was not in rc before I made this change. How is controlled which device management is used without this flag?
Beyond it, thanks for your support. |
