[Hallcsw] cdaq cluster shutting down at 3pm on July 3, will return July 8 (at the latest)

[Brad Sawatzky]

Dear Collaborators,

The machine hosting cdaqfs is scheduled for downtime on July 5 for an OS
upgrade.  Because that machine hosts home/ and other critical partitions
on the cdaq cluster, all cdaqlX and ccomptlX machines will also be
offline until that machine is back up.

Note this will also impact the qweakdb mirror running on cdaql3.  If you
have farm jobs that pull DB data from cdaql3.jlab.org instead of
qweakdb.jlab.org, then they will stall/fail.

I plan to shut the cluster down at 3pm on July 3, please halt any jobs
under your control and anticipate downtime extending Thursday through as
late as Monday morning.  Note that I will *try* to bring the machines
back by the end of the day on Friday but I can not promise that they'll
be back up for the weekend.  If I miss the window on Friday then it will
have to wait until I can get access to the computer room Monday morning.

I'll send out an email when the machines are back online.

-- Brad
