BOINC database downtime

The LHC@home database will be down for a while this morning, due to a network interruption in the CERN data centre. Hence scheduler requests and uploads will fail for a while.



Sorry for the trouble and happy crunching.

Interruption to CMS@Home, Wednesday 15th July

We need to interrupt the CMS project tomorrow to deploy a new Workflow Management Agent. This means that jobs will not be available from sometime tonight. We recommend that you set your CMS machines to No New Tasks as soon as possible, to avoid tasks terminating with an error if a job can't be fetched.

We anticipate jobs will be available again late Wednesday (European time). I'll update this thread when it is OK to proceed.

CMS job rundown

We need to do some tests of a patch to fix a bug that's been plaguing us for some time. To this end, I am letting the job queues drain, so there will be an absence of CMS jobs -- perhaps as soon as tomorrow morning, depending on how we continue to recover from today's Oracle quota problem.

So, be prepared to set No New Tasks as soon as you see any sign of lack of jobs -- or sooner if you prefer.

I don't know how long the testing will take, there are many factors at work (if the BOINC server sees that there are no jobs available, it will stop sending tasks; that will mean it takes longer for each test batch to be recognised and start serving jobs).

Downtime Saturday

The database underlying LHC@home will be down on Saturday 27th of June due to an upgrade of a DB storage rack.



Hence LHC@home BOINC services will be unavailable for a good part of the day. (Est 5:30-12:30 UTC)



So your BOINC client connections to our servers are likely to fail on Saturday.



Thanks and happy crunching!

Server outage Wednesday

Due to a failure of a database storage system, a number of database services at CERN failed on Wednesday afternoon. The LHC@home servers were affected as well, as the BOINC database was unavailable and requests timed out.



Sorry for the trouble and happy crunching!
