 |
|
Hello all. I recently (this weekend) updated my 1.4rc1 system with the command:
After that, I went through the updated config files via etc-update and made changes where I thought applicable.
Upon rebooting, I get a couple errors indicating that the filesystem has been repaired. The first indication that things weren't working is I cannot access any of my optical drives (1 SCSI CDR, 1 IDE DVD-ROM and 1 IDE DVDR).
An lsmod shows the modules loaded, but cdrecord -scanbus gives the following:
| Code: | Cdrecord 2.0 (i686-pc-linux-gnu) Copyright (C) 1995-2002 Jörg Schilling
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.
|
To further make things worse, I cannot mount /boot (among other things).
My /etc/fstab is:
| Code: | # /etc/fstab: static file system information.
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/fstab,v 1.10 2002/11/18 19:39:22 azarah Exp $

# noatime turns of atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail and tail freely.
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/hda1 /boot ext3 noatime 1 1
/dev/hda3 / ext3 noatime 0 0
/dev/hda2 none swap sw 0 0
/dev/hdb1 /mnt/music ext3 noatime 0 0
/dev/cdroms/cdrom2 /mnt/cdrom iso9660 user,noauto,ro 0 0
/dev/cdroms/cdrom0 /mnt/cdr iso9660 user,noauto,ro 0 0
/dev/cdroms/cdrom1 /mnt/dvdr iso9660 user,noauto,ro 0 0
proc /proc proc defaults 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink). Adding the following
# line to /etc/fstab should take care of this:
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will use almost no
# memory if not populated with files)
tmpfs /dev/shm tmpfs defaults 0 0

The final piece of the puzzle is I went into /dev to look around and here is what I see:

Obviously there is a lot missing, like my hard drives, etc.
I can get on the net, but that's about it. I am going to continue trying to solve this problem , but if anyone has any answers, they'd be VERY appreciated as there is a lot I can't do on the system (obviously).
Thanks!

replace your /dev with the one in the stagexx tar file.....i.e. mv /dev /dev.old
mv stagexxx/dev /dev |

Thanks for the quick reply. Upon backing up I get:
| Code: | | mv: cannot move `/dev' to `/dev.old': Device or resource busy |
Any ideas?
Thanks! |

Also, I tried the following:
| Code: | mkdir /dev.old
cp /dev -r /dev.old
|
That worked and then:
| Code: | | cp -r ~/stage1/dev/* /dev |
This copied the files over (I verified; however, upon rebooting, it was back to what it was before. Why can't I learn to leave well enough alone!!! |

Ok success!!! I had to copy over the devfsd.conf from the stage1 tarball in addition to copying over the contents of stage1's /dev.
Now, the big question, what did I do to screw things up in the first place? If it was during the etc-update, I went through each file and if devfsd.conf was there (I don't remember), it sure didn't have contents that would blank mine out!
Thanks! |
