Description Keiichiro Tokunaga 2009-04-21 20:42:31 UTC
Created attachment 340629 [details]
A proposal patch

Description of problem:
The following two lines are displayed when mounting fs fails at the
2nd kernel (kdump kernel) boot time.

  umount: Couldn't umount /mnt: Invalid argument
  [: 0: unknown operand

Version-Release number of selected component (if applicable):
kexec-tools-1.102pre-56.el5

How reproducible:
Always (when mounting fs fails).

Steps to Reproduce:
1. Configure kdump.conf to use a filesystem.
2. Trigger a panic or something so the 2nd kernel starts booting.
  
Actual results:
The two lines are displayed.

Expected results:
The two lines are not displayed.

Additional info:
A proposal patch attached.  It just follows the manner done in the
nfs case.  The patch is against the latest kexec-tools (1.102pre-65.el5)
as of today.

How can you produce "Invalid Argument" in umount, can you give a command? I don't know how to get an "umount: Couldn't umount /mnt: Invalid argument" error message, thus I can't reproduce this bug.

Comment 9 Keiichiro Tokunaga 2009-08-06 23:22:57 UTC
If mounting the filesystem fails, the "Invalid Argument" should be shown.  And, to make the mount failure happen, I think you can modify mkdumprd a bit.  For example, inserting "dd if=/dev/zero of=<filesystem> count=1000 bs=1024" right before the "mount" command runs, or changing the line of "mount" command to 
"ls there-is-no-file" or something should work.
