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 Problems with user disks

Dear all,

due to a problem with the file server that provides the /user on T2B, we will need to reboot this machine to get more diagnostics.

This intervention is planned around 1:30. Until then, you can keep working, but avoid doing large copies (or hadd) to the /user disk as this will freeze up the machine you are working on. For now, do all large copies towards the /scratch. Later today the final copy can then be done.

While the server is rebooting, you will no longer have access to your files. Reboot should take ~20 minutes. We will notify once the server is operational again.

Kind regards,

The T2B admin team.

  • After the reboot, all seems to work as expected. We will continue monitoring for faulty disks.
