Dear Bi Users,

we need to upgrade Lustre server software on Accumulus, this downtime 
is for the main part of Accumulus that was not upgraded three weeks 

Downtime will start Tuesday 9 February 09:00 CET.

End of downtime is as soon as we are done but it may take as long as 
three days.

During downtime Bi will be unavailable and all Accumulus filesystems 
(/nobackup/*) will be unavailable on Tetralith.

On Tetralith, please try to avoid scheduling jobs depending on 
Accumulus filesystems that will not complete before, or start during 
downtime, as they will otherwise fail.

Kind Regards,
Fredrik Nyström, National Supercomputer Centre
