Hi, I'm facing the same situation as described in bug #57084 (https://tracker.ceph.com/issues/57084) since I upgraded from 16.2.13 to 17.2.6 for example: root@faiserver:~# getfacl /mnt/ceph/default/ # file: mnt/ceph/default/ # owner: 99 # group: nogroup # flags: -s- user::rwx user:s-sac-acquisition:rwx group::rwx group:acquisition:r-x group:SAC_R:r-x mask::rwx other::--- default:user::rwx default:user:s-sac-acquisition:rwx default:group::rwx default:group:acquisition:r-x default:group:SAC_R:r-x default:mask::rwx default:other::--- root@faiserver:~# getfacl /mnt/ceph/default/.snap # file: mnt/ceph/default/.snap # owner: 99 # group: nogroup # flags: -s- user::rwx group::rwx other::r-x </pre> Before creating a new bug report, could you tell me if someone has the same problem with 17.2.6 ?? Kind regards, Arnaud
