Storage Issues, 6pm Friday Feb 24

The Network Appliance servers for EECS Home directories, Project space and some Instructional storage have been intermittently affected. This may affect other services which depend on the storage, e.g. personal web pages.

Fileserver maintenance
Upgrading NetaApp OS 11am-2pm on Presidents Day holiday 20th February
Department fileservice may experience some short interruptions during the maintenance window, approximately 11am until 2pm.
Many services that rely on access to department fileservice (home directories, webservice, repo service, NFS and CIFS mounts, etc) may notice some performance issues during this period.
We expect most, if not all, clients to recover automatically once work is complete. This news item will be updated to indicate when the maintenance is completed.
Systems still experiencing mount issues after the maintenance window, would need to remount or reboot.

EECS Full Network and Service Outage, Thurs. 12/22/16 7:30AM
We will have a full system shutdown on Thursday, December 22nd at 7:30 AM to perform necessary fire and emergency power testing in our server rooms. The entire EECS network and all hosted resources will be offline during this maintenance.
This will affect networking in the following locations:
Wired and wireless networks offline:
* Soda Hall
* Cory Hall
* Sutardja Dai Hall
* Jacobs Hall
* BWRC
Wireless networks offline, wired remains online:
* Blum Hall
* Calvin Lab
Hosted resources such as the EECS website, file servers, etc. will be offline and globally inaccessible.
The facilities maintenance window is scheduled from 7:30 AM to 1 PM, but we anticipate the network and critical services should be back by 11AM if all goes well.
The intent is to perform these tests annually going forward; however we will learn from this year’s procedure and aim to keep more critical services online in the future.
If you have any questions about this maintenance, please contact help@eecs.berkeley.edu.

Fileserver maintenance, Nov 24 10am
On the morning of Thursday, November 24 (Thanksgiving Day), we will be performing some disruptive maintenance on the department fileserver:
* Recable to new network datacenter switches.
* Upgrade cluster switches firmware.
* Upgrade NetApp OS.
Department fileservice will be unavailable during the maintenance window, approximately 10am until 1pm. Many services that rely on access to department fileservice (home directories, webservice, repo service, etc), will either be offline or will fail to work during this window. All NFS and CIFS mounts will be affected.
We expect most, if not all, clients to recover automatically once the fileservers are back online. This news item will be updated to indicate when the maintenance is completed.
Systems still experiencing mount issues after the maintenance window, would need to remount or reboot.

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

Continuing Home Directory Migration
As
previously announced, we are in process of migrating our central file storage
system to a new cluster of Network Appliance hardware. We recently completed the
first
batch of migrations.
We are planning to migrate additional home directories
according to the following schedule:
Start time
Wed Jan 27 7pm Usernames a-h
Thu Jan 28 7pm Usernames i-o
Fri Jan 29 7pm Usernames p-z
You may view the list of accounts targeted for this migration here:
List of homes to migrate
We expect each night’s migration to be completed by 7am the next morning.
Home directories targeted for a given evening will become unavailable at 7pm, as
automount maps are updated. When your home directory migration is completed,
you will be sent an automated email telling you so, and it will be immediately
available for use.
If you require postponement of your home directory migration, please let us know
as soon as possible at help@eecs. We’ll do our best to accommodate you,
and schedule an alternate time for migration.

(The following is reproduced from the previous announcement.)
If you manually mount your home directory, please read on for changes.
If you have questions about some of the technical details,
please contact your system administrator(s), or contact help@eecs.
1) NFS exports will change. AMD/automaps will be updated accordingly.
Note that this implies a re-mount.

2) CIFS/Windows access will change similarly. Active Directory will be updated
accordingly, so that corresponding H: drives will be mounted from the new
location.
