Such a file cannot be accesses (except via .lustre/fid) and cannot be removed.</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre># ls /mnt/lustre ls: cannot access /mnt/lustre/d0/d1: No such file or directory t:lustre-release# sys_getdents -x /mnt/lustre d 200000007000001 '..' d 2c0000402000003 'd0/d1' d 200000002000001 '.lustre' # </pre> </div></div> <p>This is a minor issue as normally llapi calls dirname() and basename() to get the directory and name. Hence this will not be encountered by (most) users. However llite and the mdt/mdd layers should better validate names that come from ioctls.</p> LU-4954
