Introduction
StashCache is implemented with the same use rinterface and database as CVMFS. The use sees the files as if they are on a local file system.
Usage
Define a read a write area
export MU2E_STASH_WRITE=/pnfs/mu2e/persistent/stash export MU2E_STASH_READ=/cvmfs/mu2e.osgstorage.org/pnfs/fnal.gov/usr/mu2e/persistent
Files to be distributed are copied interactively to the appropriate area under the stash cache directory.
cp foo $MU2E_STASH_WRITE/path/foo
Interactively, or on any grid node, the use can copy it locally if a fast disk response is needed
cp $MU2E_STASH_READ/path/foo .
or simply open it as a local file.
The cache area is not executable.
