Pinning Files to a Pool

You may pin a file locally within the private pool repository: 

(<poolname>) admin > rep set sticky <pnfsid> on|off

the ’sticky’ mode will stay with the file as long as the file is in the pool. If the file is removed from the pool and recreated afterwards this information gets lost.

You may use the same mechanism globally: in the command line interface (local mode) there is the command 

(<poolname>) admin > set sticky <pnfsid>

This command does:

  1. Flags the file as sticky in the name space database (pnfs). So from now the filename is globally set sticky.

  2. Will go to all pools where it finds the file and will flag it sticky in the pools.

  3. All new copies of the file will become sticky.
