[QA] Fwd: NFS server hardware swap this Thu Oct 10

Tue Oct 8 11:37:35 UTC 2013

Hello,

The beta cluster will be down for a brief period of time for a scheduled
maintenance.

I will attempt to connect during that time to make sure the beta cluster
is going back on properly.

Hello all,

As will come as no surprise to anyone, we have had difficulties with the
stability of the hardware of the Lab's NFS server for some time.

In an effort to fix that service, we will be switching the hardware
underlying that service to new hardware this week (2013-10-10) at 18:00
UTC (14:00 ETD / 11:00 PDT).

The switch proper should only cause a brief (~10m) outage but since the
switch requires a rebuilding of the filesystem it means that services
using NFS will need to be restarted at its conclusion.

For Tool Labs this means that continuous services will be restarted and
cron job suspended during the outage, but will resume automatically at
the conclusion.  Non-continuous jobs will not be restarted automatically.

-- Marc
