== Achievements this week ==<br />
<br />
* LHCb fully migrated to Echo :D :D :D<br />
* Facilities headnodes have been created and have inventory personalities.<br />
** Agreed that GP and CP to produce a plan on how to do this.<br />
* Aquilon disk servers ready to go, also queued behind tape robot<br />
** Designing a stress test based on CC meeting (IOZone on SL6, IOZone on SL7, compare)<br />
* DUNE have been set up on WLCGTape<br />
<br />
== Operation problems ==<br />
<br />
* T2K issues with finding files on tape (GGUS 140870) - Currently on Alastair<br />
* ATLAS are periodically submitting SAM tests that impact availability and cause pointless callouts - Currently with TA<br />
* Nagios alert for subject alt names on stagers needs updating. With production team.<br />
<br />
== Plans for next few weeks ==<br />
<br />
* Examine further standardisation of CASTOR pool settings.<br />
** CASTOR team to generate a list of nonstandard settings and consider whether they are justified.<br />
* Castor tape testing to continue after the production tape robot networking is installed<br />
* Decommission lhcbDst then move them to wlcgTape<br />
** Consult with Raja on decommissioning.<br />
<br />
== Long-term projects ==<br />
<br />
* New CASTOR WLCGTape instance.<br />
** Migration of name server to VMs on 2.1.17-xx is waiting until aliceDisk is decommissioned.<br />
* CASTOR disk server migration to Aquilon.<br />
** Need to work with Fabric to get a stress test (see above)<br />
* The problem of castor-functional-test1 has been absorbed into the task of sorting out worker node grid-mapfile generation and distribution.<br />
** RA to make a VM for James<br />
<br />
== Actions ==<br />
<br />
* 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. <br />
** Some discussion about what exactly is required and how this can be actually implemented.<br />
** CASTOR team proposal is either:<br />
*** 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.<br />
*** to run a recursive nschmod on all the unneeded directories to make them read only.<br />
*** CASTOR team split over the correct approach.<br />
* Problem with functional test node using a personal proxy which runs out some time in July.<br />
** RA met with JJ, requested an appropriate certificate.<br />
** GP to follow up with JJ<br />
* RA and DM to sit down to sort out storage metric question<br />
** Plan to create new metrics for GridPP6.<br />
