Achievements this week
- New facd0t1 disk servers
- All new facd0t1 disk servers are in production and working without issues
- We will then retire the old servers
- Facilities headnodes requested on VMWare, ticket not done yet.
- Willing to accept delays on this until ~May.
- Queued behind new disk, tape robot and a number of Diamond ICAT tasks.
- Acceptance testing of the new tape robot completed
- New-style tape server installation ongoing.
- Tape library ready for CASTOR-side testing
- Aquilon disk servers ready to go, also queued behind tape robot.
Operation problems
- ATLAS are periodically submitting silly SAM tests that impact availability and cause pointless callouts.
- Rob has created a ticket with Tim, work is being done.
- CASTOR metric reporting for GridPP.
- Looking for clarity on precisely what metrics are relevant, and given CASTOR's changed role, what system RA should report on.
Plans for next few weeks
- Examine further standardisation of CASTOR pool settings.
- CASTOR team to generate a list of nonstandard settings and consider whether they are justified.
- CASTOR side tape robot testing.
Long-term projects
- New CASTOR WLCGTape instance.
- LHCb migration is with LHCb at the moment, they are not blocked. Mirroring of lhcbDst to Echo complete.
- CASTOR disk server migration to Aquilon.
- Change ready to implement.
- Deadline of end of April to get Facilities moved to generic VM headnodes and 2.1.17 tape servers.
- Ticket with Fabric team to make the VMs.
- RA working with James to sort out the gridmap-file distribution infrastructure and get a machine with a better name for this than castor-functional-test1
Actions
- AD wants us to make sure that experiments cannot write to that part of namespace that was used for d1t0 data: namespace cleanup/deletion of empty dirs.
- Some discussion about what exactly is required and how this can be actually implemented.
- CASTOR team proposal is to switch all of these directories to a fileclass with a requirement for a tape copy but no migration route; this will cause an error whenever any writes are attempted.
- RA to look at making all fileclasses have nbcopies >= 1.
- Problem with functional test node using a personal proxy which runs out some time in July.
- Rob met with Jens, requested an appropriate certificate.
Staffing
- RA out for the next two weeks, at HEPiX next week, on A/L the week after.
