Operation problems
gdss650 (LHCbUser) failed on Saturday morning, 3rd Dec. It was returned to service on 6th Dec. A disk had failed - and the replacement to that disk also failed. During the RAID rebuild a further disk drive started reporting problems and was also swapped.
gdss701 (LHCbDst) was taken out of service on Saturday (3rd Dec) when it reported FSProbe errors when a disk was replaced. It was returned to service on the 5th Dec.
There a problem on one of the Power Distribution Units to a rack in the UPS room during the early hours of Monday morning (5th Dec). This affected two network switches - which in turn affected some core services
Operation news
Five CV11 disk servers from aliceDisk (gdss613, gdss614, gdss615, gdss616, gdss617) have been drained and decommissioned RT176040
LHCbUser and LHCbDst disk pools have now been merged. LHCbUser are in read-only mode and will be drained out of data mexxt week RT181921
Plans for next week
CV13 disk server firmware upgrade. need to decide on an intervention plan that minimizes service disruption and it is effficient enough to complete in reasonable time
Initiate the 2.1.15 upgrade path on preprod
Long-term projects
Castor 2.1.15 upgrade has been postponed until January 2017
First draft of castor tapeserver features completed and published for review.

RA to talk to AL about merging old CMS tape pools
Start gathering tape recall stats for ATLAS RT177612
Delete empty dirs from CASTOR (prompted by BD)
Consider to move puppetdev to new hardware or VM (suggested by Kashif) RT177712
