What is the better way, to "copy" this database, if :
- I use ssh connection, so users system /etc/passwd (simple copy / add user after each creation on client?)
- I use ftp, with database, and uid / gid are virtual (no reference on /Etc/passwd and /etc/group)
how are you doing?
regards

The MDS needs the user database. Without that, you get that error.

The Lustre MDS needs the user and database (/etc/password or whatever you are using). Without that, you get that error.
