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/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-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

by

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.

Resolved as of 2011-05-09 21:05:00

UPS Installation/Various System Outages

by

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

by

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 – Maintenance/Upgrade on Home/Project/IMAP services

by

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.

Storage Problems

by

We are currently experiencing issues with IMAP, Home, and Project Storage. Staff are currently working on resolving the issue. News will be posted when services are restored.

There has been an outage on project and IMAP server earlier today. While the service has been restored, we are continuing to monitor it and investigate the root cause. Depending on the vendor recommendations, we may have to schedule additional work on a relatively short notice.

December 28th Shutdown

by

IMAP/mail, home/project, Windows services (AD/WINS/printing), LDAP/NIS/DNS, DHCP and most other IDSG and IMG services will be affected. We will try to keep some basic network services running (DHCP, DNS/NIS), possibly in a reduced capacity.

While EECS-Secure, EECS-Guest and EECS-Open wireless LANS will be out of service during this time, the EECS and AirBears wireless LANS will remain operational during the outage.

The reason for this extended downtime is multi fold. The first is to repair the UPS that failed a couple of weeks back. The repaired unit will be placed back on line and extensive testing must be done to ensure it’s operation before we can depend on the UPS again. The second is to move data around which will allow us to remove from service a piece of software used to manage storage. This software is no longer under development and we need to remove our dependency on it. Lastly, some routine maintenance will be done which can only be done when systems are down. These are the kind of things that can only be done between semesters and we ask for you understanding during this disruption in service.

While the stated outage is from 10:00AM to 9:00PM, it may not take that long. This is a worst case scenario. If possible, services will be brought up sooner than 9:00 PM.

Unplanned storage/email outage

by

Departmental storage went offline around 2:40PM affecting Home Directories, Project Storage and IMAP/E-mail service.

Service has been restored and IRIS staff are investigating further into the causes and full extent of this outage. If you are still having problems with these or other services, please contact the [IRIS Helpdesk – (formerly known as EECS Helpdesk)](mailto:help@eecs)
