Continueing upgrade of storage machines

Dear all,

In the past few weeks, we have added memory to a dozen of our storage machines. This operation is now finished. We have already seen that this has increased the stability of the /pnfs system.

Kind regards, Olivier, for the T2B team

Dear all,

We are continuing the upgrade of our storage machines by adding more memory. This has proven to be the key ingredient for a more stable /pnfs. As we need to stop the machine before adding memory, a small number of files will be unavailable during this process. Which files exactly are unavailable will change during the day, as we will upgrade 8 machines. As a rule, the files should be unavailable for less than 1h.

Kind regards, Olivier, for the T2B admins
