ECE Storage Migration (Aug 15 and Aug 22, 2015)

ECE IT will be performing a series of data migrations this August to move data from the Klinck Data Centre to the new University Data Centre. This migration is required due to aging hardware which has reached its end of life for support, such that we can no longer guarantee the reliability of the storage.

Schedule

The IT team is planning to perform the cut-overs in two batches.

• Saturday, Aug 15th (from 9:00 pm – 12:00 am): Selected users affected*
• Saturday, Aug 22nd (from 9:00 pm – 12:00 am): All users affected

 * Users with the following home directories and research storage locations:

  /ubc/ece/home/coop/…
  /ubc/ece/home/kc/… (Prof. Karen Cheung)
  /ubc/ece/home/maor/… (Prof. Martin Ordonez)
  /ubc/ece/home/ngrads/…
  /ubc/ece/home/staff/…

Impact

During these outage windows, the affected home directories (including IMAP mail and personal web hosting) will be temporarily unavailable. During the second weekend, ECE websites will be temporarily unavailable as well.

What users need to do?

Users are asked to log out of their sessions on the ssh-linux servers and Linux workstations when they leave the campus on Friday. Any network filesystems that are still mounted during the cutover will need to be forcibly unmounted, causing your processes to be terminated. Service should return to normal by Sunday.

Despite these precautions, you may need to reboot your Linux workstation if the network filesystems were not unmounted properly. If you encounter any issues or have any questions after the migration please contact the ECE IT team (help@ece.ubc.ca).

Questions?

Please feel free to contact us if you have any questions or concerns regarding this migration. You can also direct your questions specific to your requirements prior to the migration to the ECE IT team via help@ece.ubc.ca .

A reminder will be sent out on Friday to remind users of the weekend scheduled outage. Thank you in advance for your support as we plan and conduct this migration.

Addendum

The SSH server upgrade to Ubuntu 14.04 will be coordinated with this migration. Since nearly all users will need to logout for the second outage window on Aug 22, we will be rebooting all ssh-linux servers and changing the default to point to the new servers.

Status

Aug 15, 22:00

The first-stage migration for August 15 seems to have completed smoothly. Please report any issues you may encounter with accessing your home directory.

Both stages of the migration appear to have completed successfully. Please report any issues you may encounter with accessing your home directory.
