*'''8 Oct. 2021 - Infiniband network back in operation'''. The broken Infiniband switch has been replaced and the Infiniband network is working again. You can make use of the Infiniband network again for your jobs on the CPU partitions.
+
*'''21 Sep 2022 - Access to ALICE:''' On 26 Sept 2022 between 18:00 and 18:30, access to ALICE will not be possible due to maintenance on the University cloud platform.
*'''8 Oct. 2021 - Node020 and node859 used for testing''' Node020 and node859 will be reserved from time to time to continue testing the new BeeGFS storage system.
+
*'''24 Aug 2022 - ALICE available again:''' Maintenance on ALICE is over. The cluster is online again and available to all users. We apologize for the delay.  
*'''30 Aug. 2021 - Node020 reserved to testing''' We have been working on the configuration of the new BeeGFS storage system. To this purpose, we have reserved node020 for running tests.  
+
*'''23 Aug 2022 - ALICE system maintenance not finished and continues tomorrow:''' We managed to solve many of the issues that we faced yesterday. We are waiting for the completion of synchronization processes which are part of the high-availability setup procedure. If all goes well, we just need to run a few tests to verify that the new high-availability setup is working properly and all the nodes are coming back. Unfortunately, it was not possible to do today anymore. In case the setup fails after all, we are prepared to revert back all the changes and bring ALICE online again. In any case, we expect ALICE to be online again sometime tomorrow afternoon. We are sorry for the delay, but the new high-availability setup is vital for ALICE which is why have been working hard to get it done.
*'''23 Jul. 2021 - Leiden University network maintenance on 31 Jul/01 Aug:''' Maintenance on the network of Leiden University will take place on the weekend of 31 July/01 August. During this time ALICE will continue to run, but in total isolation, i.e., with no internet access. This means that you will not be able to login to ALICE and jobs cannot for example pull code, download data or access license servers. During the maintenance, the status will be tracked here [[News#Next_Maintenance|Next maintenance]]
+
*'''22 Aug 2022 - ALICE is offline due to system maintenance - Continues tomorrow:''' We encountered unexpected technical issues during our highest priority task for this maintenance day, the high-availability setup. Because this is a critical component for the continuing stability of ALICE and we require the cluster to be offline, we decided to continue solving the issues tomorrow and keep the cluster offline.
*'''29 Jun. 2021 - ALICE system maintenance finished (Update):''' System maintenance has finished and ALICE is available again.  
+
*'''17 Aug 2022 - REMINDER - ALICE system maintenance on 22 Aug 2022:''' We will perform system maintenance on ALICE on 22 Aug 2022 between 09:00 and 18:00 CEST. Our primary focus will be the high-availability set up of ALICE in addition to other maintenance tasks. This will require us to take all compute and login nodes of the cluster offline. It will not be possible to run any jobs and access data on ALICE. The login nodes will be rebooted and all active terminal or X2Go sessions will be terminated. Until maintenance starts, you can continue to use ALICE as usual and submit jobs. Slurm will also continue to run your job if the requested running time will allow it to finish before the maintenance starts. If you have any questions, please contact the ALICE Helpdesk.
** However, <s>two</s> one issue remains.  
+
*'''01 Aug 2022 - ALICE system maintenance on 22 Aug 2022 - First announcement:''' We will perform system maintenance on ALICE on 22 Aug 2022 between 09:00 and 18:00 CEST. Our primary focus will be the high-availability set up of ALICE in addition to other maintenance tasks. This will require us to take all compute and login nodes of the cluster offline.

Slurm will also continue to run your job if the requested running time will allow it to finish before the maintenance starts. If you have any questions, please contact the ALICE Helpdesk.
** <s>Login node 1 is down due to technical issues on the node. Login2 is running and can be used instead. Connections that are intended to login1 are automatically routed to login2. There should be no need to change your ssh configs. </s>
+
*'''01 Jun 2022 - Disabled access to old scratch storage:''' As previously announced, we have disabled access to the old scratch storage. '''We will keep the data available until 30 June 2022'''. Afterwards, we will start to delete data so that we can repurpose the storage within ALICE. You can request temporary access by contacting the ALICE Helpdesk. See also the wiki page: [[Data storage|Data Storage]].
** The Infiniband network is down due to technical issues on the Infiniband switch.
 
** List of changes:
 
*** Login node 1 is running and the NVIDIA Tesla T4 has been integrated successfully. Instructions on using the T4 will follow soon.
 
*** Slurm version 20.11.7 is now running on ALICE
 
*** EasyBuild 4.4.0 is used for the Intel and AMD branch
 
*** The partitions notebook-gpu, notebook-cpu, playground-cpu, playground-gpu have been removed.
 
*** The time limit on the mem partition has been changed from Infinite to 14 days.
 
*** Resources on the testing partitions are now limited to 15 CPUs per node, a maximum amount of memory per node of 150G, a default memory per cpu of 10G.
