Short outage on GitLab fixed

Sunday, 4. December 2016: our GitLab is up and running again. The GitLab was offline for a few hours. Thanks to Roli Gisler for his quick alert. Thanks to the elcore team specialy to Sandro and Dario which did a great Sunday afternoon job. We’re investigating actually the root cause. I’ll publish the culprit here.
Update 5. December 2016: After a brief investigation we found several issues leading to a SCSI-vhci lock-up. This seems to be an issue with the excessive load and the SATA card. We’re planning to move the repo data from SATA storage to our Hitachi block storage and attaching the LUN’s over Fibre Channel to the NAS head. This should prevent us from further disruption.
