Fire cluster upgraded to Rocks 4.1 OS. It was therefore unavailable from 13:00 to 17:00 (no users were currently using fire, and no jobs were running).
Configuration changes
Automatic removal of old files in /work on fimm
/work on fimm now has automatic removal (delete) of files when usage is over 80% for the filesystem. The script similar to that on tre: it deletes files older than 21 days, then older than 14 days and so on... untill usage is below 80%. Do NOT touch your files to keep it new, it will only cause the filesystem to go 100% full and jobs to crash. /work2 will be added to the script later.
Support address has changed
NOTUR has changed domain from notur.org to notur.no
The email support address of support-uib@notur.org has therefore changed to support-uib@notur.no (hpc-support@hpc.uib.no can also be used)
Web-access to support has changed accordingly from https://support.notur.org to https://support.notur.no
NOTURs webpages can now be found on http://www.notur.no
FIMM downtime
FIMM was down for scheduled maintanance 2005/05/09 08:00-10:00 = 2 hours of the full cluster.
The work that was done was:
o upgraded firmware on SATABlades
o move /local from the local disk of each node, to a shared disk, to save precious space for local /scratch usage.
Home directory on fimm – Please read if you’re using fimm.
Because of major stability problems caused by NFS, the home directories has moved from NFS to GPFS on fimm. We hope this should fix all performance issues for the home-directories, and also make fimm more robust. It should no longer be depending on external filesystems, and the load on the regatta shouldn't affect the fimm-cluster anymore.
The new home directory on fimm is under /home/fimm/$department/$username/. This is only accessible on fimm.
The old home directory was /home/parallab/$department/$username/. This will still be the home directory on TRE, but if you only or mainly use FIMM, please move your files from /home/parallab, to /home/fimm/.
Very sorry for any inconvenience this sudden change has caused, but the situation on fimm was getting quite bad, and something needed to be done.
OpenSSH upgraded (with S/Key)
OpenSSH was upgraded to version 3.8.1p1 and configured to support S/Key autentication (OTP). S/Key autentication is a one-time password system that makes it possible to log in securely from any internet cafe without worrying about anybody logging the password that was used during log-in.
Reprogrammed tape robot call home
The tape robots obviously call IBM every now and then to verify that the call home feature is working. IBM had changed their phone number, so this have been failing lately. IBM-support came by today and fixed this both for Para//ab and the informatics.
Support for prioritized and unprioritized NFR quotas
The maui scheduler will now notice if a project has run out
of prioritized cpuquota, and move them to the FREECPU QoS.
There they will get lowest priority.
