Hi all,

After a power failure, my RH7.2 is not able to boot up.  It said that was an unclean system shutdown.  And display several "Bad file descriptors" error while trying to mount the root partition.  When it ask me to press "Y" to preform system check during the boot, I pressed 'Y' and it said unable to preform test due to unable to mount /proc/partitions.  The boot process stop and prompt me to enter root password for maintenance.   I tried to boot into "Linux Rescue" and perform fsck, but still doesn't help. I also try the maintenance, but whatever I try to do, it said no /proc/partitons mounted. I tried to preform e2fsck but it said something like /dev/null not able to read.  
There are 2 things I would like to perform on either one:

1. Recover the system
2. somehow bootup the system with network connection so that I can transfer my data out and perform a clean install

Solution is highly appreciated. Many many many thanks.

Try to fsck your harddriver on another Linux machine.

I was not able to bootup after I attach the crashed disk as a primary slave to another RH8 system...it said something like "duplicated /boot detected"...

OK, try to bypass all that weird auto stuff. Command line should be like this: "<your-kernel-name-on-working-drive> root=/dev/hda1 (probably your active Linux partition) ro". This should get you started.

I think that your first step should be to check the system partition and then try to start your system with that drive.

i have perform the check using both fsck and e2fsck under linux rescue mode as mentioned, it checked ok, but none of these help on booting up.  When I perform these check under maintenance mode, it said /dev/null not able to read.  But i found that this file exist under the directory.

thanks

ls -l /dev/null shoud show something like:
crw-rw-rw-    1 root     root       1,   3 2001-08-31  /dev/null
Is that right in your case ?

sorry about the late.  I couldn't get the question solved.  My solution is to get another harddisk and copy the data out, then do a clean installation
