OSCER users,

We have concluded home1 maintenance, and you should be able to submit jobs again.

We will continue to monitor the health of the home1 server over the coming days to verify that the software version rollback has been effective at improving server stability.

OSCER users,

Access to home directories on home1 have been shut off
and we are making the final synchronization of home1,
in preparation for the software rollback tomorrow.

If your home directory is on home1 and you log in,
your working directory will be set to root (just a slash)
instead of your home directory.

We hope to have your home directory access restored
at a reasonable hour tomorrow (Tue July 15). [...]

OSCER users,

Can you please share the announcement below with
anyone who might be interested and appropriate?

OSCER Scheduled maintenance partial outage Mon July 14 4pm - Tue July 15 5pm CT

2025-07-10T20:24:54+00:00

OSCER users,

OSCER Scheduled maintenance partial outage
Mon July 14 4:00pm - Tue July 15 5:00pm Central Time

Affected systems: Supercomputer, home1 users only (~50%)

In order to minimize risk and disruption for users on home1,
we've decided to do the software rollback this coming
Tuesday (July 15), with user access to home1
shutting off Mon July 14 4:00pm Central Time,
in order to do the final copy of user files (to avoid data loss). [...]

Re: Schooner: disruption on home1

2025-07-09T19:45:56+00:00

OSCER users,

Hopefully an improvement:

Because home1 has been failing daily, we expect that
it will happen again tomorrow (Thu July 10).

If that happens, we'll take that opportunity to
do the final file synchronization (which we now hope
will be much quicker than the first one), then
roll back the software, and then reboot home1.

If things go well -- NOT GUARANTEED -- no running jobs
will crash as a result. [...]

Re: Schooner: disruption on home1

2025-07-09T19:30:30+00:00

OSCER users,

We've completed the first file synchronization of home1 to
other storage as a secondary copy in case of trouble. It took
less than a full 24 hours (more like 15 hours).

We'll shortly start draining home1 users' running batch jobs.

NOTE: For home1 users who are running long batch jobs,
either in the OSCER-owned longjobs or longlargemem queue,
or in a condominium queue, those jobs will end up getting
killed. [...]

OSCER: Home server back online.

2025-07-09T17:30:51+00:00

OSCER Users,
The /home fileserver issue this morning has been fixed. If you have any issues still, please contact us at support@oscer.ou.edu<mailto:support@oscer.ou.edu>. We strive to improve all OSCER systems. We apologize for any inconvenience.

Thank you
Dave

Re: Schooner: disruption on home1

2025-07-09T16:41:59+00:00

OSCER users,

For now, the issue on home1 is TEMPORARILY resolved.

But, expect further disruption until we can address
the root cause of the problem.

We apologize for the trouble!

Henry

Schooner: disruption on home1

2025-07-09T12:15:01+00:00

OSCER users,

As some of you have noticed, we're continuing to experience
disruption on one of Schooner's /home subsystems (home1).

We believe that the cause is a bug in the combination of
software versions that we're using to implement home1,
specifically the version of the Linux operating system and "ZFS."

(ZFS is the storage software that both home1 and
some /scratch subsystems are built on.) [...]

Re: OSCER home directory issues

2025-07-08T10:52:40-05:00

Hi again,

the systems are back up, so you should all be able log in again.

Please send email to support@oscer.ou.edu if you are still experiencing
any issues.

Thanks,

There was a problem with one of our /home fileservers,
which is fixed.

If you experience any problems on any OSCER storage,
please alert us as quickly as possible.

It might be that a few users are still experiencing issues with
scratch storage, but we should be able to resolve those
straightforwardly. [...]
