Hello everyone,
We are running lustre 2.12.7 and today I tried to set up a few nodemaps
so as to restrict access to an unique user (seamless user with uid/gid
3669) to a subdirectory (/webservices/seamless) from a range of machines
(10.0.1.[35-38]).
Here's what I did so far :
lctl nodemap_add seamless
lctl nodemap_add_range --name seamless --range 10.0.1.[35-38]@tcp
lctl nodemap_modify --name seamless --property trusted --value 1
lctl nodemap_add_idmap --name seamless --idtype uid --idmap 3669:3669
lctl nodemap_add_idmap --name seamless --idtype gid --idmap 3669:3669
lctl nodemap_set_fileset --name seamless --fileset '/webservices/seamless'
lctl nodemap_activate 1
However, when I tried to log on one of the machine NOT in the
10.0.1.[35-38] range with my user account (uid 2154), my home directory
ownership got immediately squashed to:
drwx------ 12 nobody nobody 4096 Apr 5 17:11 rey
So I immediatly deactivated the nodemaps using :
lctl nodemap_activate 0
However, the directory ownership remains nobody/nobody and I can no
longer log in.
Does anyone know how to revert this ? And what was wrong with my
nodemaps configuration ?
Thanks.
