Dear Users,</p>
<p>this is to give you an update about the Leonardo maintenance. It is almost<br />
completed and we expect to bring the cluster back to production within the<br />
afternoon. However, there are important information to be taken into account.</p>
<p>As already announced, during the maintenance a technical issue to the cooling<br />
system occurred that affected a few controller components of the scratch<br />
filesystem, preventing the access to a small number of disks and the mount of<br />
the filesystem on the compute nodes. So, at the moment, when opening<br />
production, the entire SCRATCH area will not be mounted on the compute nodes.<br />
It will be accessible only from the logins.<br />
As a consequence all the jobs making use of the SCRATCH area will fail until<br />
the issue is solved.<br />
We suggest, thus, to cancel all of your jobs using SCRATCH area and resubmit<br />
them making use of the WORK area that will be fully operative. You may need<br />
to copy data from SCRATCH to WORK before resubmitting the job.</p>
<p>While copying, it is possible that some files may not be accessible because<br />
present in the physical disks of the storage with the controllers affected by<br />
the issue described above. We are working to restore them.</p>
<p>We will promptly inform you as soon as we have important updates on this.</p>
<p>We apologies for the inconvenience.</p>
<p>Best regards</p>
