Scheduled Storage Outage, Fri. 3/11/16 10PM

March 11, 2016 by Derek Calderon

This Friday at 10PM we will be doing a software upgrade on the switch which provides connectivity for the EECS storage infrastructure. This upgrade is to address an issue with in-band management of the switch.

All storage services (home directories, project storage, etc.) will be briefly unavailable during the upgrade. Past experience suggests that this downtime will only last approximately five minutes. We strongly recommend that you save and close all open files in home and project spaces before 10PM on Friday. Machines with permanent NFS mounts may need to be rebooted after the maintenance is complete.

Please contact help@eecs.berkeley.edu with any questions or concerns.

Major Upgrades on June 6, 2009

June 6, 2009 by IRIS Staff

On Saturday, June 6th, we will be doing major upgrades to some of our
backend systems. This work will start at 10 am. We expect that some of
services will start coming back up in about 3 hours, but due to the
complexity and extensiveness of the upgrades, the downtime may extend well
beyond the 3 hour mark. These upgrades are imperative for the continuing
reliability of the infrastructure services. We apologize for the
inconvenience.

The following services will be affected:

* Home directories
* Project space
* UNIX SWW
* Departmental/IDSG web servers
* IMAP (due to the additional work, IMAP will be down for an additional 2 hours)
* argus/login (UNIX login servers)
* Department websites www.eecs / www.cs and all hosted project sites
* Department mailing lists hosted on lists.eecs
* buffy and all ACG applications
* wikis hosted on wiki.eecs
* Department’s jabber server, jabber.eecs

Coeus/Project Downtime

August 20, 2008 by IRIS Staff

Attention System Administrators,

On Wednesday, August 20th from 6am-8am, IDSG will be migrating production file service of home directories and project space to the new NetApp filers. There will be downtime during this migration that will impact the majority of users in the department. Please evaluate the impact for your users and notify them of those details. A much shorter public announcement will be going out soon to the entire EECS community indicating that local System Administrators will be letting them know of any specific information as to how it will impact their work.

The following services will be affected:

– coeus
– project
– sww (not winsww)
– argus
– www.eecs and www.cs web servers
– the IRIS website

The following changes apply:

1. COEUS

– coeus.EECS.Berkeley.EDU will be replaced by home.EECS.Berkeley.EDU.

– NFS access will change from coeus:/vol/vol0/eecs/username to home:/eecs/username

– The amd and automaps will be appropriately changed.

– CIFS access will change from \\\\\\COEUS\HOME\username to
\\\\\\HOME\username

– The old hostname coeus will be a CNAME to home.EECS.Berkeley.EDU until September 20th.

2. PROJECT

– NFS access will change from project:/vol/vol[02]/projspace to project:/proj/projspace

**NOTE**: A few mount points will change in a different way. See the end of this announcement for details.

**NOTE2**: If your project spaces are merged, the details will be worked out with you directly outside of this announcement.

– The amd and automaps will be appropriately changed.

– CIFS share names will not be affected.

This announcement may be followed by additional updates if additional technical details need to be publicized. Certain requests may be delayed beyond the normal response time (e.g. amd/automap change requests, new user creation, project space creation, etc.) during the 2 weeks prior to the migration.

The downtimes for different services will be different. There will be one or more additional announcements as services get restored to allow early access to the appropriate systems. E.g. the actual downtime for coeus/home is expected to be only a few minutes.

This list will receive notice when access is restored.

Sysadmins should be ready to reboot systems that need to remount filesystems between 7:30 and 8 AM. CIFS access should resume during that time as well. The CIFS share names will not change and therefore should not require a reboot for those systems.

Be advised that there are a number of follow-up tasks after the outage, which could result in slow response from these systems.

If you experience problems during or after the outage, or have
additional questions – please contact Helpdesk at help@eecs or 2-7777 or 395 Cory.
