Service:

• Updated OSG to 3.5 on 2 out of 3 gatekeepers, the ATLAS production gatekeeper is still on 3.4, waiting for condor update on our cluster.
• Testing and updating condor from 8.6.13 to 8.8.7, encountered some problem due to the new features of 8.8.7-1, with some workaround, fixed the problems. Also plan to rebuild all the work nodes with a seperate parition for condor jobs instead of sharing it with /tmp.  The condor head node is also a SL6 node, we plan to update it to SL7 with condor 8.8.7-1.
• dcache is updated to 5.2.16, it took longer than what we planned
• had problem with the dCache database (zpool problem), took half day to recover it, HTCondor ramped down due to this and also a related ggus ticket  146141(solved)  and 146144 (same as 146141, request to close)on 22nd March 2020
