There was an interrupt in storage connection to /home filesystem. This rendered /home to be read-only, we are working to fix this problem ASAP.
Update 16:08 We are running fsck on /home, access is still closed
Update 19:50 Fsck has finished booting machine
Update 20:18 Machine is back online

Dear fimm cluster users:

We have recently added two extra login nodes (login2 and login3 ) to fimm.bccs.uib.no. Current login1 will be go under maintenance for short period of time,and will be added back eventually.

We kindly ask you to save your current work on login1 and log-off from login1 and relogin again, you will landed one of login2 or login3. When you do "ssh fimm" DNS server will pick login node according to round-robin scheduling.

Eventually we will have 3 login nodes on fimm(login1, login2,login3), all of them has identical hardware, you can ssh between login nodes.

We have done this to increase redundancy and uptime.

Let us know if this caused any problem for you.

Hexagon is going to have a scheduled maintenance on April, 23rd. The
maintenance will start at 9:30. The expected downtime is about 12 hours.

During the maintenance we are going to do the following:

* Upgrade the compute node Linux to 4.2UP02.
* Upgrade the management station base OS and Cray software release.
* Apply different security patches.
* Upgrade the storage firmware.

All running jobs will terminated. The job submission system has a
reservation in place, it will not allow to start jobs which will not
be able to finish before the maintenance start.

Update 20:10 The maintenance is over. The machine is back online.

Hexagon has updated compilers and libraries.

requirers electricity to be switched off completely.

Therefor fimm.bccs.uib.no cluster and grunch server will be
shutdown for 3 hours. We have reserved cluster for maintenance which
means jobs submitted to cluster which can not be finished by that time
will not run, and jobs which is already running but will not be able to
finish by that time will be killed.

Maintenance will start from 09:00 AM in the morning. We would advice
you to save all your work on fimm.bccs.uib.no and
grunch.bccs.uib.no by that time.

We are sorry for inconvenience, and appreciate your understanding.
