Description

We should move /grid/data to the FERMI-BLUE-1 data head.

The /grid/data/*/LOCK ifdhc locks areas need to be
shifted to /grid/app first,
to decouple them from data overloads.

History

#1 Updated by Arthur Kreymer over 5 years ago

The security model of /grid/app is correct for this usage.
Mounted and writeable on all Fermigrid and interactive systems.

As an initial step,
existing /grid/data/*/LOCK areas can be symlinked to
/grid/app/ifmon/ifdhc/group/*/LOCK

Eventually locks should be based on the disks accessed,
the Bluearc 'span' rather than the users' group ID,
with locks in /grid/app/ifmon/ifdhc/span/*/LOCK.
Let's discuss this in a separate issue.

#2 Updated by Steven Timm about 5 years ago

It may be that the /grid/data can be realigned as part of the new blue arc buy that was done this fall. M. Votava and S. Fuess know this issue has to be discussed as part of the deployment plan.
