Hello all,
like announced on last Sunday I hereby announce a maintenance-window for
Monday, 20:00-22:00 UTC for the web-servers.
I will reboot hemlock a few times to try to find out why the web-servers are not working if hemlock is away (and if I find it, I will fix it). All web-tools will failing in times when hemlock is (re-)booting, other sub-systems (like SGE) should working normal.
The maintenance is done. I have identified the nfs-service at hemlock as the root of the problem. However I confused by the result: If I stop the nfs- service completely the webservers fail (like expected). If I remove all nfs- shares on hemlock and start the nfs-service the webservers fail too (also ok). But it is not possible to identify the share that cause the problem, because if I remove each share separately and restart the nfs-service afterwards the webservers did working (some times they needed a moment, but at the end they worked). I have to think about this first before I can take further steps.
All maintenances for today are done. You can work normal now again :-).
Sincerely, DaB.
