others permission), then it's ok

i test it, and in node,I add user "linx" to group "kvm"
$ cat /etc/group | grep "kvm"
kvm:x:112:qemu,vdsm,linx,sanlock
then i create a file in $HOME:
$ ls -l
总用量 16
-rw-rw---- 1 vdsm kvm 6 9月 11 20:06 1.txt
drwxr-xr-x 9 linx linx 4096 9月 1 15:58 linx-virtualization
drw-rw---- 3 linx linx 4096 9月 11 20:13 test2
drw-rw---- 2 linx linx 4096 9月 11 20:19 test3
then we can view the file in user "linx":
$ cat 1.txt
pencc
leases if vdsm:kvm too:
$ ls -l
/rhev/data-center/mnt/192.168.11.55\:_home_dataStorage/1845be22-1ac4-4e42-bbcb-7ba9ccd6e569/dom_md/leases

_home_dataStorage/1845be22-1ac4-4e42-bbcb-7ba9ccd6e569/dom_md/leases
but we cannot read the file in user "linx":
$ cat /rhev/data-center/mnt/192.168.11.55
\:_home_dataStorage/1845be22-1ac4-4e42-bbcb-7ba9ccd6e569/dom_md/leases
cat:

权限不够
why is this? follows the nfs server configure
# cat /etc/exports
/home/dataStorage 192.168.11.*(rw,sync)
/home/dataStorage2 192.168.11.*(rw,sync,no_root_squash,no_subtree_check)
/home/isoStorage 192.168.11.*(rw,sync,no_root_squash,no_subtree_check)
Is my nfs-server configurations miss some arguments? have any idea?
Try to setup a supported system (e.g centos, fedora) and compare the setup.
Can explain why user linx need access to vdsm/sanlock/qemu data?
