[Labs-announce] NFS server switch 2014-04-30 19h UTC

[Marc-André Pelletier]

Hello Labs,

On 2014-04-30 at 19h UTC we will switch NFS service from one server to
the other (labstore1001 -> labstore1002).  This is to allow upgrading
labstore1001 to Debian Jessie - bringing it up to date with our current
infrastructure and having a kernel that is more performant for our
setup.  Labstore1002 (the server we are switching to) has already been
rebuild with Jessie.

To be safe, since that procedure has not yet been tested live, I am
setting a 30 minute maintenance window during which NFS service may be
stalled.  However, I expect no outage beyond a brief (2-3 minute) stall
of NFS while the instances reconnect to the new server.
