147770 UKI-NORTHGRID-LANCS-HEP very urgent in progress 2020-07-13 09:11:00 UKI-NORTHGRID-LANCS-HEP: stage-out failures
- still seeing periods of overloaded disk servers; plan to help ease our disk server problems later in the week with zfs tuning
- O(3PB) new servers with empty space; decides to write to the empty machine, hence overloads it; similar issues seen at GLA and SHEF
- Discussion on storage solutions and interaction bettween experiments and sites followed; some notes:
- Infrastructure and maintainance, difficicult to fund this.
- Experiments change their mind, based on current needs … planning for the wrong eventualities
- Sam - number of hurdles for new technologies; and assumptions of established code working
- Experience with setting up a DPM xroot cache woks well
- Use of cache to ‘change type’ eg. direct-io to locally staged.
- GLA, proxy cache to talk to DPM, for local users (set up with existing hardware)
