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/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.

UPDATE

The storage migration work scheduled for tonight has been completed. If you experience any problems accessing storage please try re-mounting volumes and also check for any static mounts. If you have questions please contact: idsg@eecs.berkeley.edu
