Swiss WLCG Operations Meeting on 2011-09-13
Agenda
Status
- CSCS:
- Update of the recent issues with Lustre and Cream.
- ARC Accounting and BDII.
- Status of EMI1 upgrade
- Migration to GPFS
- PSI (reports Fabio):
- We suffer almost every week of 1TB failed disks, it takes time to replace the disk / check the ZFS rebuild / apply the Oracle/DHL process and bureaucracy for the new disk.
- We're investigating a new 200TB raw storage, several vendors invited to make an offer, so far I've discovered these products:
- UNIBE (reports Gianfranco):
- Stable operations, ATLAS production and analysis. Also some SMSCG activity
- Running stably with CVMFS since a few months now
- Had to recover DPM install because of EPEL conflict (operations not affected)
- Upgrade to ARC1 postponed due to Lustre bugs
- Starting now with KVM
- UNIGE (reports Szymon):
- Daily operations very stable and quiet, nothing to report.
- A major upgrade of storage going ahead:
- IBM x3630 M3 with 12 x 3 TB of disk for data + two small disks for the OS
- hardware RAID, we will do RAID 6 with cold spares, 27.5 TB net/machine
- we are getting 10 machines, only 8 can be powered up soon
- to stay in fixed kW budget we will retire 12 login machines, in operation since 2005
- most of the new disk servers will be added to our Storage Element
Other topics
- CernVMFS updates (the requirements meeting is a different meeting)
