The "halld" volatile disk is going to move to a new file server running
a modern version of Lustre. The switch should be nearly transparent to
users; files will be rsync'ed to the new server and then the link cut
over to point to the new partition. The only catch is the period just
before and including the cut-over. If new files are being written to the
old partition while the final rsync is in progress, or during cut-over,
they may not make the transition successfully. For this reason we want
to have the disk quiet (as far as writing) for a few hours before cut-over.
I would like to schedule this quiet period for Thursday morning, June
25, from 8 am to noon. Then we will do the cut-over. Let me know if this
schedule is not convenient for any reason.
