Description Gabriel Rocha 2012-04-17 14:55:24 UTC 
+++ This bug was initially created as a clone of Bug #813345 +++

Description of problem:

the kdump.conf manpage states thus:

<fs type> <partition>
Will  mount  -t  <fs type> <partition> /mnt and copy /proc/vmcore to /mnt/var/crash/%DATE/.  NOTE: <partition> can be a device node, label or uuid.

However, mount -t auto works (it also works in fstab) and it does not work in kdump.conf with an error regarding fsck.auto which does not exist.

This becomes an issue when you have a mixed deployment of rhel5.7 and 5.8 where the default filesystem changed from ext3 to ext4 and the customer's standard kdump.conf stopped working...

Version-Release number of selected component (if applicable):

kexec-tools-1.102pre-126.el5_7.7 (rhel5.7)
kexec-tools-1.102pre-154.el5 (rhel5.8)
kexec-tools-2.0.0-209.el6_2.5.x86_64 (rhel6.2)

How reproducible:

Easily...

Steps to Reproduce:
1. In kdump.conf specify your filesystem type as 'auto'
2. service kdump restart
  
Actual results:

Stopping kdump:                                            [  OK  ]
Detected change(s) the following file(s):
  
  /etc/kdump.conf
Rebuilding /boot/initrd-2.6.18-274.14.1.el5kdump.img
/etc/kdump.conf: Unsupported type auto: fsck.auto not found
Failed to run mkdumprd
Starting kdump:                                            [FAILED]

Expected results:

The kdump service should restart normally and automagically identify between ext3/4 with the 'auto' fs option as mount does.

Additional info:

This can also be seen as a simpler documentation bug where the man page should specify that the filesystem type must exist and cannot be 'auto.' It should also explain what happens with that line and that a corresponding fsck.* executable must exist...
