Comment 2 Bruno Goncalves 2015-11-20 05:20:12 EST
The update works after umount /var/crash.

# rpm -q kexec-tools
Comment 4 Xunlei Pang 2016-01-13 04:47:41 EST
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.

Comment 5 Bruno Goncalves 2016-01-13 05:44:30 EST
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 2016-01-13 20:22:35 EST
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.

Comment 7 Bruno Goncalves 2016-01-14 04:30:20 EST
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.

# mount <NFS share> /usr/share/doc/util-linux-2.23.2/

# yum update util-linux

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.

Comment 9 Xunlei Pang 2016-01-25 22:38:36 EST
We regard this as a general issue, so close it as "not a bug".
