So, for people wanting to know, the migration has started. 1) gerrit ---------- gerrit seems to be ok, it has a new IP 66.187.224.201 people who used to have access there need to contact me so I can explain/create required account on the new virt host. the old VM is shutdown for now. I will make a backup copy of the disk. 2) jenkins ---------- so the preparation of the migration didn't worked as well, so we have to copy the VM when offline, and then prepare it later ( ie, import in libvirt, adjust network, etc). So jenkins master is offline (sorry manu for your tcpdump monitoring), we are making a copy of the disk that is gonna take between 3 and 14h (most likely < 4h, but rsync estimation is moving a lot), and then restart like before. If anything is broken, please do not hesitate to tell us. I will send a email to tell when people can start again to submit patch and stuff :) -- Michael Scherer Sysadmin, Community Infrastructure and Platform, OSAS
