Mass Storage (/pnfs) adding memory to some PNFS nodes

Hello,

Today we are going to add memory to some storage nodes to alleviate failures from the last couple weeks.

This means nodes are going to be unavailable one by one for 30-45min, the time for the operation.

We'll inform you when everything is finished.

Cheers, the T2B IT Team
