Hi ,

When I setfacl default in lustre directory, I got unmapping group id(getfacl) after first setting(setfacl) . Then I execute setfacl command again and got fail ( Operation not permitted).

1.cat /etc/passwd
user1:x:1001:1001::/home/user1:/bin/bash

2.nodemap setting
nodemap.21b7e9f04fed448e.idmap=
[
.....

,
.....
]

3.setfacl steps
[root@hsm client]# mkdir hadoop3
[root@hsm client]# getfacl /mnt/client/hadoop3
getfacl: Removing leading '/' from absolute path names

1. file: mnt/client/hadoop3
2. owner: root
3. group: root
   user::rwx
   group::r-x
   other::r-x

[root@hsm client]# setfacl -R -d -m group:user1:rwx /mnt/client/hadoop3
[root@hsm client]# getfacl /mnt/client/hadoop3
getfacl: Removing leading '/' from absolute path names

1. file: mnt/client/hadoop3
2. owner: root
3. group: root
   user::rwx
   group::r-x
   other::r-x
   default:user::rwx
   default:group::r-x
   default:group:23501:rwx
   default:mask::rwx
   default:other::r-x

[root@hsm client]# setfacl -R -d -m group:user1:rwx /mnt/client/hadoop3
