Dear Cyclone and Grunch Users,

Our machine room at Thormøhlensgate 55 will have power outage during Friday 17 April 15:00 to Sunday 19. April 24:00.

There will be planned work to do maintenance for power line in the building.
Because of that maintenance, we have to take down all our servers at 15:00 Friday 17. April and hopefully we will take all servers online before 08:00 Monday 20. April.

cyclone and grunch server will be taken down and will not be accessible during this time.

/shared/ filesystem which is exported via leo.hpc.uib.no to the university campus will not be accessible during this time.

We advice all users to plan their work in good time to avoid unnecessary problems.

Update20:30_19.04.2020: Our downtime is over, cyclone and grunch is back online. 
Please contact us via hjelp.uib.no if you have any further questions.

Best Regards

Scientific computing team.

Some of the servers and other equipment in our server room have to be relocated. Due to this process, Cyclone and Grunch server will have short downtime today at 11:00, estimated downtime is about 30 minutes.

Please save all your work before 10:45 and log out safely.

Don't hesitate to contact us if you have any questions via hjelp.uib.no.

Update: 13:45: maintenance is over, all services are online, we are sorry for the delay.
Update: 20:00: we are still experiencing a communication issue between the file server, this can cause /shared filesystem unresponsive or slow, we are working on the issue.
Update 22:00: Problem resolved.

Dear Cyclone and Grunch users:

We will have a short downtime at 10:00 21/02/2020, expected downtime is about 30 minutes. Please save your work in advance and log out safely before 09:45 on the same day, after this time users will be removed. We apologize for the short notice and the inconvenience it may cause you.

Feel free to contact us via hjelp.uib.no if you have any questions.

Update: 10:25  Unfortunately we have to extend our downtime until 12:00 today.
Update: 11:55  downtime extended to 13:00 today.
Update: 12:30  Downtime is over. We manage to move home directory of users from the different server back to /shared filesystem,  please log in to your account on Cyclone and Grunch, check all your files are there and permission is correct.

Dear Cyclone and Grunch server users:

We discovered possible filesystem corruption on /shared Lustre filesystem today. To eliminate data loss, we have to take down /shared filesystem and run filesystem check immediately to make sure that the filesystem is not corrupted.

We plan to start at 12:50 today.

User login to Cyclone and Grunch will be locked during the process, and all NFS and smb exports will be terminated.

We are sorry for any inconvenience this may have caused, and we will keep you updated on this page.

Please contact us via https://hjelp.uib.no if you have any further questions.

Update 14:00 : The filesystem check is running.

Update 20:50 : The filesystem check is still running, we will continue tomorrow.
Update 21.01.2020_13:40:  /shared filesystem is back online, and user access for cyclone and grunch is enabled.  NFS and SMB is started.  There might be some data loss under /shared/projects/gfi/ folder, make sure that you go through your important files and report back if you missing some files. So far, we identified one file loss from this folder which we will make direct contact with the owner of the file.
