Hi, I have Lustre 2.3 mdt/ost and clients. I have the lustre fs mounted as /home on the client. The client has cPanel/WHM running which is used to manage the server. Now there are 2 odd things happening. 1. Any user''s home directory if it''s on the /home lustre mounted partition I can''t login to it via SSH using RSA keys. 2. I can''t add any account using cPanel/WHM, I get permission denied errors: Copying skel files from /root/cpanel3-skel/ to /home/sstest/...tar: ./public_ftp: Cannot mkdir: Permission denied tar: ./public_html: Cannot mkdir: Permission denied tar: .: Cannot utime: Permission denied tar: .: Cannot change mode to rwxr-xr-x: Permission denied tar: Exiting with failure status due to previous errors When /home is not lustre mounted it works just fine. One other odd thing is that I could add an account via WHM fine yesterday with the lustrefs mounted as /home but it no longer works for unknown reasons. I get no errors in the logs on mdt/ost. I mounted the lustre fs like this: mount -t lustre -o user_xattr,flock mdt at tcp:/lustrefs /home Am I missing something?

How you autenticate your clients? ldap, local user? Maybe you must test ?echo NONE > /proc/fs/lustre/mdt/<your_filesystemname>-MDT0000/identity_upcall?. This sentence avoid the MDS know the uid:gid clients.

Have you checked your permissions on the /home directory before you mount it?
