RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

+++ 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...
