Mass Storage (/pnfs) /pnfs has sometime issues

Hello,

For the last few days, /pnfs is having performance issues, while some storage nodes can't serve files. We have not identified the cause yet.

Mainly cd/ls becomes slow, and only a restart of the service makes it work fast again. Also, a couple of storage nodes have a hard time serving files (hence why some of your files have issues), this usually solves itself after a while.

Cheers, The T2B IT Team

Batch System [17/07 4PM] [Prevision] Batch System down due to maintenance on electric line at datacenter

Hello,

Du to a planned intervention on the electrical line at the datacenter, we are asked to stop all compute nodes during the maintenance.

Therefore, on Monday 17/07 starting at 4PM, all worker nodes of the batch system will be stopped. Jobs running will be automatically killed. Other services like storage (/pnfs, /user), websites, mX machines should stay available during the maintenance.

The batch system will be available again on Tuesday 18/07 by 11AM.

Sorry for the inconvenience, The T2B IT Team

  • Hello,

    The maintenance operations have finished successfully, the ressources are getting back up in the batch system. You can now start sending jobs again. Note that jobs in the queue have been started automatically.

    Network Issues with VUB network affecting cluster

    Hello,

    Since this morning, there seem to be issues with the VUB network, that can affect the connection to T2B cluster. The service comes and goes, at this time it is working but it might not stay that way. We will watch the situation as it unfolds. Unfortunately the issue is from the VUB network side, so there's nothing that we can do.

    Cheers The T2B IT Team

  • Everything seems to have gone back to normal.
