Replacement of nodes of the distributed disk system

On next Saturday November 16th at 22:00h we have scheduled the replacement of one of the nodes of the distributed disk system. This task will probably take more than 24 horus to complete, given the amount of data to move (up to 32 TB of data are involved).

This task will imply noticable impact over all services, which may render them unaccessible during long periods of time until the task is completed.
