Continuing Home Directory Migration

January 27, 2016 by Lars Rohrbach

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.

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>

UPDATE

[2016-01-28 12:52:42 | Lars Rohrbach]

The Wednesday night home directory migration did not get through all of the a-h accounts. A couple of c’s and all d-h will be postponed until Monday Feb 1 at 7pm.

A list of all successfully migrated accounts is available here: Migrations complete

Tonight’s scheduled migration will begin with the letter ‘i’ as planned. Our noted exceptions are listed here: Exclude from migration


UPDATE

[2016-01-29 16:25:41 | Lars Rohrbach]

Tonight we continue with usernames r-z.

Home directory migrations for those that didn’t complete this week, and for some who have postponed, are being scheduled for next Monday, Tuesday, and Wednesday (Feb 1-3).

Start time
Mon Feb 1 7pm      Usernames c-f
Tue Feb 2 7pm      Usernames i-q (most of i-l is done)
Wed Feb 3 7pm      Usernames g-h (and some postponed)


We will be in touch with postponed/excluded account holders to confirm whether the timing is acceptable, or coordinate an alternate time for migration.
