One of the legacy global filesystems will be migrated to new hardware on Wednesday February 20th. To complete this we must unmount the filesystem from all clusters and prevent jobs from running during the outage.

All legacy clusters will be configured to avoid running any jobs after 3pm on February 19.

We expect all legacy clusters to return to service the following day at 10am.

This outage does not affect Graham or Orca.

There will be another power outage at the McMaster datacenter, at 7am on September 29. All systems will be shut down before this time (so any jobs running at the time will be killed.)

There’s been a fibre cut (in London, around 11am) which has killed both links from McMaster to the Sharcnet WAN. As a result, several clusters are unreachable (in general, jobs will hang in this condition, since they won’t be able to do IO to global storage resources.)

This sort of thing is usually fixed fairly soon (hours); we’ll update when we know more.

A planned building power outage requires shutting down Wobbie, Iqaluk and Cat tonight. Queued jobs will remain queued, but running jobs will be killed.

Systems will be available again in the morning.
