[LU-14804] Moving a directory to lustre reports Operation not permitted when nodemap is set

Related — Fri, 30 Jul 2021 17:44:42 +0000

When a nodemap is set, moving a directory from outside of Lustre to inside Lustre reports "Operation not permitted" error.

This can be reproduced with a nodemap like the one below, where admin and trusted properties are set to 1.

[root@s20 ~]# lctl get_param nodemap.s20.*
nodemap.s20.admin_nodemap=1
nodemap.s20.audit_mode=1
nodemap.s20.deny_unknown=0
nodemap.s20.exports=
[
 
]
nodemap.s20.fileset=

nodemap.s20.id=5
nodemap.s20.idmap=[

]
nodemap.s20.map_mode=both
nodemap.s20.ranges=
[
 { id: 5, start_nid: 10.128.8.171@tcp, end_nid: 10.128.8.171@tcp }
]
nodemap.s20.sepol=

nodemap.s20.squash_gid=99
nodemap.s20.squash_uid=99
nodemap.s20.trusted_nodemap=1

[root@s20 ~]# mkdir /tmp/s20_test
[root@s20 ~]# mv /tmp/s20_test /lustre
mv: preserving permissions for ‘/lustre/s20_test’: Operation not permitted

Error is returned from mdt_reint_setxattr().
