ifdh cp locks¶
These are implemented via files in the Bluearc system,
using the same lock as the earlier 'cpn' scripts.
Details are documented under
- Locks are managed for each client group via files under /grid/data/<groupname>/LOCK
- Locks can be handled at a net rate of about five per second.
- Locks perform efficiently with queues of up to 50,000.
Locks should be taken based on disks accessed, not the user's group.
Locks should be moved from /grid/data to /grid/app,
so that /grid/data can be moved to the data Bluearc head.
Locks could be done via a web service, for remote access and better latency.
