Recreate the filesystem structure: Make sure that the following directories exist in the scratch filesystem: <verbatim> # Create Nordugrid skeleton. After this, you need to restart ARC services. cd /gpfs mkdir -p home/nordugrid-atlas/sessiondir mkdir -p home/nordugrid-atlas/cache chown nordugrid-atlas.atlas home/nordugrid-atlas -R chmod 1777 home/nordugrid-atlas/sessiondir mkdir /gpfs/home/egee/ # Required for /home/egee/, WNs and CREAM have a symbolic link in /home/egee to /lustre/scratch/home/egee mkdir /gpfs/home/egi_PP/ # Required for PP mkdir /gpfs/tmpdir_pbs # Where the jobs run #/CREAM_CE/cream01/ # <-- Only if the cream01 stores the shared filesystem to store the cream sandbox </verbatim> 1. Destroy user accounts and all data related to the old grid users existing in the system.<verbatim>/opt/cscs/sbin/clean_grid_accounts.bash</verbatim> 1. Run YAIM 1.
