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

User Interfaces - mX machines Important file server down

Dear all,

one of our main files servers is off-line at the moment. Therefore the M machines are not accessible. We are trying to get all running again asap.

Kind regards, the T2B admin team

  • The storage server for /user and websites is back online. You should be able to connect to m1, m4, m5 (check updates in a couple hours as maintenance on the other machines is starting now)
