[HPDD-discuss] Big problem with files rights

Hi, After a crash of our OSS and a few miseries, we could finally remount ou lustre filesystems. File rights are well displayed, but some of them have ? instead of owner, grp, rights. And especially, as root I can access all files, but if I place as another user, the owner of the files displayed, I can not read some of them, file permission not granted! Lustre 2.1.6 with OSS/MDS RHEL 6 and clients RHEL5. Can anyone help ?
