Sutardja Dai Hall power shutdowns

by

Sutardja Dai Hall will have two power shutdowns that impact some storage services. cluster.eecs and inst-fs.eecs will experience a short downtime at the start of each outage, however they will NOT be down for the whole duration of the outage.

The scheduled times for the power outage are as follows:

Thursday July 21st – Power off at 8:00pm and restored at 6am Friday July 22nd

Tuesday July 26th – Power off at 4am and restored at 8am July 26th

Update: the second power shutdown for the 26th was canceled.

Storage Migration

by

home.eecs and project.eecs will be down from 8pm to midnight on July
12th, 2011 to be migrated to new equipment. The actual downtime is
expected to be much smaller.

The rest of this notice is primarily targeted at system administrators.
If you choose to read this and have questions about some of the
technical details, please contact your system administrator(s).

1) NFS exports will change. AMD/automaps will be updated accordingly.
Most changes will be straightforward. Some project spaces will be
handled differently, see the details below. Note that this implies
a re-mount.

    Old                        New
home:/eecs/<user>     home:/vol/home/eecs/<user>
project:/proj/<name>  project:/vol/proj/<name>

2) CIFS shares will not change (except for the specially-handled project
spaces). However, SMB2 will be enabled (including durable filehandles).

3) The following project spaces will be migrated differently:

     Old NFS export                 New NFS export
project:/proj/aneureuther       cluster:/vol/cproj/aneureuther
project:/proj/b-cam             cluster:/vol/cproj/b-cam

project:/proj/yelick            cluster:/vol/cproj/yelick
project:/proj/yelick-old        cluster:/vol/cproj/yelick-old

If the project space in the above list had CIFS share(s) associated with
it, the said share(s) will retain their name, but will now live on
\\\\\\CLUSTER\<share_name>.

If you have questions or concerns about the timing or technical details,
then please email me at aculich@eecs.berkeley.edu or drop by 319 Soda;
as many of you know, Fred Archibald has retired and I have taken over
his role managing IDSG, so whether or not you have storage questions,
feel free to drop by my office to say hello and introduce yourself.
