Network cable switchover and disk upgrades for IRIS file servers on June 4th at 3pm

June 4, 2013 by IRIS Staff

On 3:00pm, Tuesday, June 4th, 2013, the network cables for cluster.eecs and inst-fs.eecs will be replaced in an effort to create more easily managed infrastructure. In addition, disk upgrades will take place on all department filers to increase available space. Minimal interruption of service is anticipated. NFS and CIFS mounts should reconnect automatically, although some windows mounts may need to be re-mounted. Maintenance may extend as long as 5pm, though system interruption should be a very short part of this window.

Department filer upgrade on 3/28 at 3pm

March 28, 2013 by IRIS Staff

At 3pm on Thursday, March 28, the department filers home, project, cluster, and inst-fs will be upgraded to a newer version of Ontap, the on-board system software. The maintenance should be non-disruptive, although some windows mounts may need to be re-mounted.

home.eecs short disruption of service at about 1pm today

February 26, 2013 by IRIS Staff

home.eecs had a short disruption of service during an unplanned failover to its partner filer at about 1:00 pm today. Service has been restored and most home directory accesses should have recovered gracefully from the disruption. Windows mounts may require a re-connection.

Storage Migration

July 12, 2011 by IRIS Staff

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/brass             cluster:/vol/cproj/brass
project:/proj/daw-a             cluster:/vol/cproj/daw-a
project:/proj/demmel-d          cluster:/vol/cproj/demmel-d
project:/proj/graham            cluster:/vol/cproj/graham
project:/proj/hilfinger-a       cluster:/vol/cproj/hilfinger-a
project:/proj/iram              cluster:/vol/cproj/iram
project:/proj/jordan-a          cluster:/vol/cproj/jordan-a
project:/proj/millennium        cluster:/vol/cproj/millennium
project:/proj/neureuther        cluster:/vol/cproj/neureuther
project:/proj/neureuther-flcc   cluster:/vol/cproj/neureuther-flcc
project:/proj/neureuther-intel  cluster:/vol/cproj/neureuther-intel
project:/proj/now               cluster:/vol/cproj/now
project:/proj/parlab            cluster:/vol/cproj/parlab
project:/proj/radlab            cluster:/vol/cproj/radlab
project:/proj/tinyos            cluster:/vol/cproj/tinyos
project:/proj/titanium          cluster:/vol/cproj/titanium
project:/proj/vision            cluster:/vol/cproj/vision
project:/proj/vision-b          cluster:/vol/cproj/vision-b
project:/proj/vision-c          cluster:/vol/cproj/vision-c
project:/proj/vision-e          cluster:/vol/cproj/vision-e
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.

Unplanned SAN outage

May 9, 2011 by Lars Rohrbach

An unplanned outage of our Storage Area Network (SAN) was quickly addressed by staff. The outage affected home.eecs and project.eecs storage, as well as the storage used by imap.eecs.

Staff responded to automated alerts, and were able to bring the SAN back online. The precise cause of the outage currently remains unknown.

UPS Installation/Various System Outages

March 21, 2011 by IRIS Staff

Delivery is expected Monday for our new UPS which will be installed in the 290 Soda Hall server room. Some services will be down for short periods on Tuesday while they are moved off of room power and onto temporary power. Later in the week, there will be a second outage while those machines are moved onto the new UPS. Additionally, there may be a longer outage of our storage systems while some upgrades are done.

While I realize that this post is somewhat vague, a lot depends on exactly when the UPS is delivered and how long it takes to install it. I will be posting more refined notes to narrow down the scope of what services will be out (and when) as time goes on.

While we realize that there may be some inconveniences for some, please bear with us as we strive update our services and minimize outages for the future

290 Machine Room Outage

February 24, 2011 by Eric Fraser

Some electrical work in 290 Soda caused the unexpected downtime of several IDSG services, including Home and Project Storage, Departmental Webservers, and others. The power has been restored. Some services are still being restored.

Work was in preparation for a new UPS system in the machine room. This involved moving some circuits on systems that have redundant power. There were not expected to be any outages at this time.

November 11, 2010 by IRIS Staff

There will be a short, scheduled maintenance/upgrade on home and project for the hour specified. IMAP will also be affected by this upgrade. The reserved downtime is 1 hour, but most likely the actual downtime will be less.
