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

Mass Storage (/pnfs) Difficult access to /pnfs mass storage

Dear Users,

Du to a huge amount of xrootd requests, /pnfs access is having performance issues. We have temporarily disabled xrootd access.

We will update you when the situation is resolved and everything is back to normal.
