Hi everyone,

Team,

The weather forecast looks good and we have many teammates back to campus
from their various summer endeavors, and some new colleagues have joined or
are in the process of joining the Lab.

Let's have a relaxing walk together to celebrate the start of the new
academic year.

Cheers,
AWD

Subject: Urgent! Gaia server reboot!
Message-ID: <CAN_-bZLYDxfN4Z28senY_ZzNE-Wwf=peoDY+-zaJhvx18m3Mag@mail.gmail.com>

Greetings!

  Gaia is a file server hosting our home directories and it is having
serious issues.
I'm unable to restart local services so the server has to be rebooted.
It will affect all slurm jobs and most likely will corrupt your data.
To minimize that risk, in 30 minutes all jobs will be canceled then the
server will be rebooted.
In other words: you have 30 minutes to stop your jobs and save what you can.

Piotr.

Update:
  Gaia is back online.
You should be able to ssh to the auton cluster if you haven't managed to
get yourself banned by trying too many times in the last hour.
I know you have deadlines now/soon but consider placing your main work
directory on zfsauton/scratch in near future.
Right now scratch can hold high load better than home directory.

Piotr.
