As
previously announced, we are in process of migrating our central file storage
system to a new cluster of Network Appliance hardware.
We have identified 703 home directories on home.eecs.berkeley.edu that are
not under immediate, active use, and will be migrating them to the new file
storage beginning late tonight, January 22, 2016. Active use was assessed using
timestamps of top level home directory, last Active Directory login, last CIFS access,
NFS mounts and netstat output. We anticipate that most of the migrations
in this first batch will take just a few minutes, and that the whole first batch
will be complete before Monday.
You may view the list of home directories that are part of this first-batch migration here:
List of home directories to migrate
During the migration, access to the old location will be disabled; you will
be able to access the new location immediately, as files are copied over.
Many users may never notice a difference. 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.

We plan to schedule the migration of the remaining home directories on home.eecs
in the coming week. Please stay tuned for more information.
