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

by

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.

Project storage migration

by

As
previously announced, we are in process of migrating our central file storage
system to a new cluster of Network Appliance hardware.

Beginning February 15 (President’s Day), we will be migrating project and cluster
storage spaces to the new hardware. Initial synchronizations will be done over the
next two weeks, so that the final sync and cutover time will be reduced for the larger project spaces.
We are initially proposing the following schedule:

Time                    Project            New mount
Feb 15 6:00-6:30pm      /cproj/nlp         proj40.eecs:/nlp
Feb 15 6:15-7:00pm      /proj/ptolemy      proj40.eecs:/ptolemy
Feb 15 6:45-7:30pm      /proj/parlab       proj40.eecs:/parlab
Feb 15 6:45-7:30pm      /proj/radlab       proj30.eecs:/proj30/radlab
Feb 15 7:15-8:00pm      /proj/efros        proj10.eecs:/efros
Feb 15 9:00pm-7:00am    /cproj/(others)    proj40.eecs:/cproj/(sharename)



Feb 16 8pm-7am          /proj/[a-c]*       proj10.eecs:/proj10/(sharename)



Feb 17 8pm-7am          /proj/[d-q]*       proj20.eecs:/proj20/(sharename)



Feb 18 8pm-7am          /proj/[r-z]*       proj30.eecs:/proj30/(sharename)



Feb 19 8pm-7am          Followup/postponed and missed migrations

If migration of your project space needs to be postponed or scheduled for
a specific time, please
let us know at help@eecs. We know that downtime for
some project spaces needs to be minimized, and
we’ll do our best to coordinate another time with you.

As with the home directories, NFS exports will change. Automount maps will be updated at the designated migration start time. Re-mounts of project spaces will be necessary.

CIFS mounts should use the new node hostnames for best performance, with the
usual sharename, e.g. \\\\proj20.eecs\macsww

NetApp filer upgrade on December 1

by

As part of our preparation for migration to new NetApp file storage hardware, we will be upgrading the OS on our existing Network Appliance file servers at 5pm Tuesday, December 1.

The OS will be upgraded from Data ONTAP version 8.1.2 to 8.2.4. Upgrade will be performed for project.eecs and home.eecs first, and then for cluster.eecs and inst-fs.eecs.

No general service interruption is expected, as our servers are configured in High-Availability pairs. Windows/SMB/CIFS users may experience a hiccup, if they have an active file transfer at the time of the upgrade; such a file transfer would terminate and need to be restarted.

Work is expected to be complete by 6:30pm.

Fileservice from cluster.eecs malfunctioning

by

After restoring other services following the network upgrade, file service from cluster.eecs and inst-fs.eecs to Soda and Cory clients continues to be severely degraded. This affects anyone who has project shares hosted on cluster.eecs, and servers that mount project shares from cluster.eecs.

Staff have been working with assistance from NetApp support to restore service for cluster.eecs.

We are currently working on various alternatives to make the filesystems accessible again. More updates will be provided on Monday.

UPS Maintenance in SDH 158

by

At 11 AM today we will be replacing batteries and performing maintenance on a faulty UPS located in our primary server and network room for Sutardja Dai Hall. No service interruptions are expected. However, in the event of a failure, there may be a ~5 minute loss of wired and wireless networking in Sutardja Dai Hall, as well as a loss of the NetApp network file storage for the EECS Instructional Labs. The maintenance is expected to last for approximately one hour, but two have been allotted in case of complication.
