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.

The update works after umount /var/crash.

# rpm -q kexec-tools
kexec-tools-2.0.7-38.el7.x86_64
Comment 4 Xunlei Pang 2016-01-13 09:47:41 UTC 
Hi Bruno,

Seems there's some permission problem with /etc/exports on your NFS server.

I tried with the "no_root_squash" NFS option on my NFS server, the update progress properly. Then I changed "no_root_squash" to "root_squash", met the same problem as your descibed in this bug.

So maybe you can try "no_root_squash" and test it.

Regards,
Xunlei
Comment 5 Bruno Goncalves 2016-01-13 10:44:30 UTC 
Our NFS server is NetApp, and they do not support no_root_squash, but they allow some other configuration that I could try [1].

But is this really a configuration issue? Note the NFS dump on RHEL-7.1 and 7.2 work well and they are saved to our NFS volume, just during the tool update that the problem happens...

If this is just how the update works, I think we can close this as not a bug.
Comment 6 Dave Young 2016-01-14 01:22:35 UTC 
Hi, Bruno

Can you try mount nfs dir which is created by other packages? See if they handle the update right. I feel it is a general issue not only for kexec-tools.

Thanks
Dave
Comment 7 Bruno Goncalves 2016-01-14 09:30:20 UTC 
Correct Dave this does not seem to be related to kexec-tools itself.

I've reproduced the problem using util-tools when updating from RHEL-7.1 to 7.2 version.

Hi, Bruno

Thanks for verifying, so I think we can regard it as a general issue and this is how update works. Close the bug is good to me.

Thanks
Dave

We regard this as a general issue, so close it as "not a bug".
