Earlier announcements and interruptions
Planned outage for ownCloud on Tuesday 11/12 between 15:00 and 22:00
It is mandatory to perform ownCloud updates and upgrades to reach version 10.x, supported by the latest synchronisation agents. Therefore we plan some maintenance windows. The last one will be on Tuesday 11/12/2018 between 15:00 and 22:00.
ownCloud service connections timeouts
Following the upgrade from 9.0.11 to 9.1.8, important updates are required within the OwnCloud solution covering all the files stored on the servers. Those massive update operations significantly increase the response time and lead to connection timeouts. Solutions are being investigated to accelerate the process or improve the response time. Once the internal updates are completed, the OwnCloud service will return to a normal state.
Planned outage for ownCloud on Tuesday 04/12 between 15:00 and 20:00
It is mandatory to perform ownCloud updates and upgrades to reach version 10.x, supported by the latest synchronisation agents. Therefore we plan some maintenance windows.
Impacted service: No access to ownCloud services, i.e. no access to the web interface and no ownCloud client synchronisation.
Tuesday 04/12/2018 between 15:00 and 20:00
Tuesday 11/12/2018 between 15:00 and 18:00
Some operations might take longer than planned and tested if unexpected conditions are encountered.
Planned emergency hardware intervention on resu1, web2, web1, edurad1 and doculb
Following a hardware fault incident on 7/11 we are running all rama services on vamana. we need to move back all virtual machines to 145rama'. Downtime is expected to be about 15 minutes maximum (dns will be a few seconds). The outage will start on Friday November 15th at 17:00.
Affected services will be: resu1 (DNS primary, radius), web2 (www.ulb, intranet ), web1, edurad1 (eduroam primary) and doculb.
DNS and Eduroam have secondary servers, so service should not be impacted
Roundcube Webmail and OTRS unavailable on Thursday November 8th
The server Krishna will be halted for a hardware repair. It is halting sporadicly (2 times in 2 weeks) with a defective component. The outage will be for about 60 minutes starting on 8/11 17H00. Impacted services are: OTRS and Roundcube Webmail.
IT maintenance on 03/08/2018: important disruptions planned
Due to extensive computer maintenance, all ULB/VUB IT services as well as Internet and Intranet networks will be completely unavailable on Friday, August 3, from 08:00 to 12:00. In case of prolonged interruption of services, we will inform you via social networks.
Hydra downtime in June from 25th to 29th
The maintenance will be used to perform the usual updates/upgrades, including security patches, and to further increase the Hydra storage (the work directory) resiliency and efficiency.
We will also bring a major change in the jobs scheduling rules: the maximum walltime will be reduced from 14 days to 5 days. From the Hydra usage statistics, less than 1% of the submitted jobs will be impacted by this change.
Users requiring to run jobs over more than five days will have two options available. The first and most useful one is that we deployed an advanced checkpointing system (stop a job and restart it where it was) which has been successfully tested on typical software running for extended period of times like Gaussian, R or Python. To safely checkpoint your jobs, you'll need to use the csub tool.
Detailed documentation on how to use csub is available on our new web site: https://hpc.vub.be/documentation/faq.html#how-can-i-run-a-job-longer-than-the-maximum-allowed-wall-time
In case checkpointing is impossible, it will be necessary to ask a reservation for a specific period via firstname.lastname@example.org or email@example.com. Note that this will be allocated case by case and the HPC team will help to eventually find alternatives or better ways to run those long jobs.
As for all previous planned Hydra downtimes, we have placed a reservation on the cluster. Jobs that can complete before June 25th 08:00 will start and the others will remain queued.
Please note that jobs still in the queue during the maintenance and with a walltime of more than 5 days will get their requested walltime changed to 5 days.
We would also like to take the opportunity to announce the availability of 21 new nodes featuring each 2x Intel Xeon Gold 6148 2.4 GHz (20 cores) and 192 GB RAM for a total of 840 additional cores! The nodes are interconnected with a 10 Gbps network and are replacing 16 of the older AMD nodes.
Thursday May 17th between 05h00 and 07h00 there can an internet interruptions
Thursday May 17th between 05h00 and 07h00 there will be a software upgrade of the BELNET routers. This means that the internet connection can be interrupted (typically 15 minutes) during this time frame.
Hydra and Vega Back Online
We have identified jobs on Hydra involved in the central storage NFS service crash. We will continue to work with the storage vendor to help them figure out why their NFS service crashed. Hydra and Vega clusters are again fully operational.
Hydra & Vega Still Unavailable
After further investigations of the NFS issue on the SISC central storage it came out that when specific private networks are made accessible to the central storage, the crash follows a few hours after. Hydra and Vega are accessing the NFS via private networks involved in the NFS crash phenomenon. To perverse other critical services relying but not impacting the central storage (like the email service), Hydra and Vega private networks have been cut out of the central storage. At this stage we still don't know if it is a rogue process or a network related issue. We continue to investigate in collaboration with SISC colleagues and the network teams.
SISC Central Storage Outage
Since Tuesday afternoon May 8th we have an issue with the central storage. Meaning that acces to ownCloud, NESTOR (z-drives in VUB computerrooms) and HYDRA storage are unavailable. A support call was logged with the supplier and we are further investigating the problem.
Planned E-mail outage on Tuesday 10 April
The SISC mailserver will be restarted on 10th of April at 17:15.
The outage will take less than 10 minutes.
Planned Internet Interruptions on Tuesday 6 March
There will be two interruptions of 15 minutes of the Internet Service on Tuesday 6 March between 5 AM an 7 AM due to a BELNET maintenance window.

Hydra security reboot on Monday January 8th
As you may have heard, two very serious security problems have been made
public last week: https://meltdownattack.com/
As such, we have to reboot all nodes of Hydra to install the fixes. The
login nodes will be rebooted this evening at 20:00. The worker nodes
will be rebooted as soon as the running jobs on them have ended. This
should have minimal impact on your work but the capacity of Hydra will
be a bit lower until all nodes have rebooted.
The bad news is that the attacks use a hardware bug and the fixes to
work around them can have a negative impact on performance. For HPC
workloads, it could mean that your applications run up to 5% slower. If
you experience more performance loss after the reboots, please
contact us at firstname.lastname@example.org
HYDRA Maintenance from 11th to 15th of December Completed
We have completed the maintenance works: Hydra is again accessible and queued jobs are now running.
1) The entire Hydra Ethernet network has been rebuilt from scratch with new switches and new cabling. All network communications have been therefore improved for a globally increased performance in data management & transfers.
2) Four new GPGPU nodes have been added, each with 2x Tesla P100.
3) The storage capacity has been increased to 800 TB.
4) The usual OS/software updates & upgrades have been made including the installation of security patches.
If you encounter any issue, please let us know by replying to this email or contacting us at email@example.com or firstname.lastname@example.org.
HYDRA Maintenance from 11th to 15th of December
We are planning a maintenance window on Hydra from 11/12 to 15/12 with a scheduled downtime.
The maintenance will be used to perform several updates/upgrades on Hydra core services including a complete network upgrade (physical and logical levels), 4 new GPGPU nodes and an increase of the storage capacity to 750 TB.
The maintenance will not kill jobs on the cluster or remove queued jobs. As for previous planned Hydra downtimes, we have placed a reservation on the cluster two weeks before the maintenance date, aligned with the maximum walltime. Jobs that can complete before the 11/12 will (continue to) run and those submitted with a walltime bumping into the maintenance window will be kept pending until the maintenance is completed.

Access to port 111 from outside the university network to be denied
As a security precaution, access from outside the VUB/ULB university network to port 111 - a port mapper - will be denied as of Wednesday, 15 February 2017. If you require access to this port, contact the ICT-Helpdesk. Read more...
Port 111 is a port mapper with similar functions to Microsoft's port 135 or DCOM DCE.
Technical details and issues: http://www.speedguide.net/port.php?port=111
Security Concerns: Provides rpc port map without auth, has no filtering or logging, rpcinfo probes can quickly find Unix hosts.
Other security issues: https://en.wikipedia.org/wiki/Portmap
The port mapper service was discovered to be used in Distributed Denial of Service (DDoS) attacks and Distributed Reflective Denial of Service (DRDoS) attacks in 2015. By using a spoofed port mapper request, an attacker can amplify the effects on a target because a portmap query will return many times more data than in the original request.
As port 111 poses quite a number of security concerns, the network team will proceed in denying access to port 111 from outside the university network as of Wednesday, 15 February 2017.

Problems with digital course recordings are solved
21 October 2016
The issues with the digital course recordings which produce errors (Panopto digilessen) are solved since October 20th.
There were occasional lockouts when connecting to a service at VUB/ULB from outside the university. These lockouts could last a couple of minutes. The network team has investigated the issues and implemented a fix on 4 October.
Telnet from outside the university to be deactivated on Monday 26 September
As of Monday, 26 September 9 AM, users will no longer be able to log in into a server at the university from a remote computer outside the university using the Telnet protocol. If you need to log on onto another computer, use the more secure protocol secure shell (ssh). Read more...
Telnet allows users to log in into a server from another computer.
Because of the numerous intrusion attempts that have been going on lately which on occasion have resulted in connectivity issues to university services (Denial of Service), the telnet protocol will be disabled for computers outside the university.
Therefore, as of Monday, 26 September 9 AM, accessing a server at the university from a computer outside the university using Telnet will no longer be possible.
If you need to log in into another computer, use secure shell (ssh) which is more secure as well (telnet connections are not encrypted and therefore not secure, especially through unsecured wireless networks).
If you have a server that only is accessible with telnet and require it to be accessibly from outside the university, send an email to ICT-Helpdesk requesting an exception. Please also motivate your request and include the name and IP address of the server.
Occasional lockouts to university services from outside the university network
The lockouts to university services from outside the university network should be solved. The network team has implemented a number of changes that should prevent these lockouts from occurring.
Hydra offline after an unplanned power cut this week-end
Due to a power cut on Friday night in the Computing Centre a lot of VUB/ULB services were unavailable on Saturday. The colleagues from ICT have worked hard to restart all services. Most of those services should be back online since Saturday afternoon. Our apologies for the inconvenience.

HYDRA power cut on Wednesday 6th of July
The compute nodes on the Hydra cluster will be stopped on Wednesday 6th of July at 20:00.
A global reservation was created on all the cluster nodes to prevent
jobs running during the power cut.
For unknown reasons, the reservation recently disappeared from the scheduler. Some jobs with a walltime beyond the power cut were therefore started. If you have running jobs, please check if their walltime will exceed 20:00 tomorrow.
The reservation was recreated.
