Home Directory Storage

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.

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.

usernames    Old                           New
a-h      home:/vol/home/eecs/<user>     home10:/home10/<user>
i-q      home:/vol/home/eecs/<user>     home20:/home20/<user>
r-z      home:/vol/home/eecs/<user>     home30:/home30/<user>

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.

usernames    Old                    New
a-h      \\home\<user>        \\home10\<user>
i-q      \\home\<user>        \\home20\<user>
r-z      \\home\<user>        \\home30\<user>

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.

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

home.eecs had a short disruption of service during an unplanned failover to its partner filer at about 1:00 pm today. Service has been restored and most home directory accesses should have recovered gracefully from the disruption. Windows mounts may require a re-connection.
