Can’t write too much as I’ve been on holiday for a week and I’ve lots to catch up on, but last night the new Geograph servers went live! At the appointed time we sync’d the database and images onto the new servers, then simply tweaked the haproxy configuration, opening the floodgates!

We’ve a couple of minor teething problems but everything seems to be holding up well!

The only major issue is every now and then the smbiod process on one of the webservers consumes 100% of the CPU, taking it out of the cluster. Not seen this issue before, will investigate it during the week. I thought Samba would be a low-maintenance solution for file sharing between servers, as I’ve never had a good time with NFS….we shall see!
