Break in file server fs.hiit.fi at 2013-02-14 16:58 - 20:36

Submitted by pmtonter on February 14, 2013 - 16:58
Schedule: 
2013-02-14 16:58 to 20:36
Duration: 
3h 38min
Affected services: 
fs.hiit.fi, shell.hiit.fi, hosted static web pages
Description: 

HIIT's file server fs.hiit.fi first partially stopped responding to SMB requests and soon after that also NFS traffic slowed down. Due to that and longish uptime the server was rebooted.

Pending operating system and firmware updates were also planned to be installed.

Update at 20:56: File service and all services depending on it are up and running. Firmware updates were skipped due to server being somehow in a weird state; firmware update hung (quite likely the first time ever). To reset the server it was removed and reinserted to the blade enclosure. Hopefully this fixes slow performance in remote management (iLO2).

Break in HPC IPv6 network connections at 2012-12-18 14:50-15:14

Submitted by pmtonter on December 18, 2012 - 14:50
Schedule: 
2012-12-18 14:50 to 15:14
Duration: 
24 min
Affected services: 
University of Helsinki department of computer science's Ukko cluster, HIIT-HPC
Description: 

HPC network was moved to another router. Due to non-activated IPv6 routing IPv6 traffic wasn't routed neither in or out from HPC-VLAN.

Configuration has now been corrected to prevent this kind of break from happening again.

Break in IPv6 network connections at 2012-12-17 13:49-13:52

Duration: 
3 min 2 sec
Affected services: 
IPv6 traffic
Description: 

Due route- network rearrangements, IPv6 routes were inconsistent and IPv6 traffic didn't flow to and from HIIT's production network.
