Re: [newbie] Unable to mount root FS on 07:07

[Randy Sweeten]

I searched Google and other search sites as Sridhar suggested, and found
little. Other folks have had this error, but none of the message threads
included the solution.

I did discover the actual error is best described by the line:
request_module[block-major-7]: Root fs not mounted.
The references to 7 and 07:07 are some kind of location descriptors, and
the problem is most likely partition related.

I booted from a install floppy and got into rescue mode.  An fdisk -l
/dev/hda gives the following:
   Device BootStart EndBlocks  Id  System
/dev/hda1 *   12032   2048224+  c  Win95 FAT32 (LBA)
Partition 1 does not end on cylinder boundary:
   phys=(1022, 15, 63) should be (1022, 31, 63)
/dev/hda2  2033   14913  12984048   f  Win95 ext'd (LBA)
Partition 2 does not end on cylinder boundary:
   phys=(1022, 15, 63) should be (1022, 31, 63)
/dev/hda5  2033   81286144232+  b  Win95 FAT32
/dev/hda6  8128  149136839752+  b  Win95 FAT32

Does anybody know what this means, and if it is related to my problem?  And
maybe some hints on fixing it?

  I'm running Mandrake's Linux for Windows, and all of a sudden I cannot
boot up
  Linux.  Boot screens show:
 
  request_module[block-major-7]: Root fs not mounted
  VFS: Cannot open root device 07:07
  Kernal Panic: VFS: Unable to mount root FS on 07:07
 
  I did nothing in Linux that I know of; it's possible my daughter booted
into
  Linux by mistake and turned off the power to get out of it.  (It's hard
to get
  a confession out of a 9 year old!)
 
  I added memory since the last time I booted Linux, and I was
experimenting
  with a USB tape drive in Windows, but did nothing about it in Linux.
And I
  tried removing the USB tape drive and rebooting Linux, to no avail.
 
  I can boot up to an Linux install disk and get to the rescue mode.  What
do I
  do there?

 I don't know about this specific error, but I have found that Google and
Google
 Groups can be great for searching for this kind of thing. Go to them and
try
 entering something like Unable to mount root FS on 07:07.

[newbie] Need copy of devices.txt

[Randy Sweeten]

I can't boot Linux due to the error 
request_module[block-major-7]: Root fs not 
found

I'm runnng Linux4Win. Linux 7.2, I 
think.

I've discovered that the Linux.bat file references 
"7", which I think is part of this error. It is supposed to be described in the 
file devices.txt, found with the kernal documentation.

Can sombody send me a copy of this file? 
Maybe it will help.

[newbie] Need to verify numeric value in bash script

[Randy Sweeten]

I'm writing a bash script to process a CSV file of billing records.  I need 
to check the last field of each record to make sure it is a numeric value, 
not a alpha character.

I can do all kinds of things to work with the specific field; I can even 
output the field to a seperate file.  I just can't figure out how to test for 
a numeric value.  I tried expr, but could not get that to work; it showed an 
error fo all of my tests.  And awk just passed over the error I planted in 
the test.

According to the book I'm using as a guide, expr should do 
it.   Maybe I've got the syntax wrong.

I've tried:
   expr $Value + 1
   It always gets a syntax error.  It is supposed to get an error like expr: 
non-numeric argument when $Value is non-numeric, but instead it always gets 
the error even if it is numeric.

Any suggestions?
