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

Network High load on M machines

Due to an upgrade of dcache, the nfs system is behaving badly. At the mometn, it creates a very high load. We are investigating.

  • Fixed by restarting the troublesome machines.
