How do I share files with members of another project?# You can use ACLs to achieve this. As a member of project group ax0001, you would have to create a directory in your project’s work for example mkdir /work/ax0001/shared It could be any other place on Lustre file systems where you have write access. Then you grant project bx0002 permissions to this directory setfacl -m "g:bx0002:rwx" /work/ax0001/shared This would allow all members of the group bx0002 to read and write the directory /work/ax0001/shared. You can check the permissions with getfacl % getfacl -p /work/ax0001/shared # file: /work/ax0001/shared # owner: b380001 # group: ax0001 user::rwx group::r-x group:bx0002:rwx mask::rwx other::r-x Why do I receive .Xauthority file error messages?
