Comment 2 Bruno Goncalves 2015-11-20 10:20:12 UTC

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".
