The problem with the GPFS parallel filesystem (/pfs/nobackup) has now been solved.
We did not see any indications of lost or damages files during the recovery process.
However you are advised to check your files to be on the safe side.
Batch queues have been reactivated.

The installation of part B of Abisko that interfered with the interim system is now finished and Abisko is now online again.

Abisko is unavailable due to system maintenance in connection with the installation of part B of the system.
We do not currently have a precise estimate of when Abisko will be accessible and accepting jobs again, but it will be before the weekend of November 26-27.

Monday Nov 21th we will be connecting new nodes to Abisko.
Due to the risk of cabling mistakes during this the batch system of Abisko will be disabled.
The cabling will take all day and possibly part of Tuesday 22nd.

Monday Nov 21th we will do a firmware update on the storage that makes up /pfs/nobackup and /hsm filesystems.
To do the update the filesystems need to be taken offline.
No batchjobs will be allowed to run and the login nodes of the clusters will be disabled.
The update will take all day.

Gaussian 09 has been upgraded to revision C.01 on Akka.
Gaussian will be available on Abisko when the final system has been installed.
Please see the Release Notes for more information about the new release. Information about using Gaussian at HPC2N is available at our Gaussian support page.
Tonight, November 2, between 22:00 and 23:00 there will be done some emergency work in the Umeå university core network. The work may also affect access to HPC2N.

Umeå Energi have fixed the leak they had in the feed to the cooling systems.
This means Akka and Ritsem have been turned on again, and the batch system has been started and is accepting/starting jobs.

Due to a leak in the feed to the cooling system Umeå Energi have to do some emergency repairs which may result in our cooling system failing and thus affecting all our clusters.
We have therefor stopped the batch systems from starting new jobs.
We will start the batch system when everything is stable again.
UPDATE (20110825):
According to Umeå Energi the cooling repairs are expected to be finished not earlier then Thursday evening/night (20110825)
Until then we have to keep Akka and Ritsem turned off due to insufficient cooling.
