Hello All, I found that issue for "stop" command is that chown command in NFS is not working . Node is not able to perform chown operation on checkpoint file i.e (for example) /srv/cloud/one/var//12/images/checkpoint. Here is the detailed information about my NFS setup configuration details and issue I am facing.
It would be great if anyone can help me in solving this issue I have create a NFS server (IP: 192.168.2.3) with following export configuration at /etc/exports: Code: /srv/cloud 192.168.2.4(rw,async,no_subtree_check,no_root_squash) >From machine 192.168.2.4 I have following configuration in /etc/fstab: Code: 192.168.2.3:/srv/cloud /srv/cloud nfs rw,hard,intr 0 0 Now from machine 192.168.2.4 with root user, I create a file "/srv/cloud/xyz" and then change the ownership of the file to user "oneadmin". I have following commands and the error in the output: Code: #touch /srv/cloud/xyz #chown oneadmin:oneadmin /srv/cloud/xyz chown: changing ownership of `xyz': Invalid argument I have user "oneadmin" at both server and the client machine with same user and group id: At client: Code: #id oneadmin uid=9000(oneadmin) gid=9000(oneadmin) groups=9000(oneadmin),110(libvirtd) At server: Code: #id oneadmin uid=9000(oneadmin) gid=9000(oneadmin) groups=9000(oneadmin) What could be the problem in changing the ownership of the file from the root user at nfs client machine when "no_root_squash" has been specified?
