Sorry my last email cut off...
Hi Just to update this. On the NFS server I created vdsm:kvm user/group Also on my debian NFS server I have in /etc/default/nfs-kernel-server RPCMOUNTDOPTS="--manage-gids --no-nfs-version 4" But the node always mounted in nfs4 (according to the mount command) >From advise in IRC I changed # nfs_mount_options = soft,nosharecache to nfs_mount_options = soft,nosharecache,vers=3 - then re attached the node - it now shows as nfs3 using the mount command and has the correct UID/GID i.e ls -al /rhev/data-center/b2b2e054-66b2-11e1-bda3-1728f784de9e/2f7ee7bc-09b3-42ba-af91-40d79293e360/images/7e2f025e-5676-4592-84fd-7c9661f5ee2e/ total 2097168 drwxr-xr-x. 2 vdsm kvm 4096 Mar 28 15:23 . drwxr-xr-x. 3 vdsm kvm 4096 Mar 28 15:23 .. -rw-rw----. 1 vdsm kvm 2147483648 Mar 28 15:23 e4aa8bf8-0cb8-4f1c-84cf-b83909f7206b -rw-r--r--. 1 vdsm kvm 320 Mar 28 15:23 e4aa8bf8-0cb8-4f1c-84cf-b83909f7206b.meta It still doesn't work...
