Kdump over nfs fails with access denied by server while mounting "bad nfs mount"

Solution In Progress - Updated -


Attempting to configure kdump on RHEL 6.10 using NFS and are running into an issue where it looks like kdump is trying nfsv4 even though nfs is specified. According to the man page, "nfs" should be using nfsv3.

kdump.conf is configured to dump via NFS:


After we modify kdump.conf per the above, we get an error when we try to rebuild the initrd:

# service kdump restart
Stopping kdump:                                            [  OK  ]

Detected change(s) the following file(s):


Rebuilding /boot/initrd-2.6.32-754.30.2.el6.x86_64kdump.img
mount.nfs: access denied by server while mounting
/etc/kdump.conf: Bad NFS mount


  • Red Hat Enterprise Linux 6 (NFS client)
  • NFSv3 mount desired for kdump (using the "nfs" option inside kdump.conf)
