Pardon my ignorance, as a recent convert to running FreeBSD in AWS, but I wo= uld like to know a little more about the possibilities that regard the under= lying file system of the official RE and Marketplace FreeBSD 11 AMIs. Ideally, I would like to have the simplicity of using the official AMIs but h= ave the option of selecting a different initial volume size (both smaller, 4= -5GB, and larger), and to turn on the standard EBS encryption at the initial= instance launch time. I realise that I can create my own AMIs, as I have do= ne over the years using CentOS. Is there an easier way and one that would no= t require my own AMI rebuilding from my own snapshots each time FreeBSD is r= eleased? Then there is the question of the actual file system. Have you opinions abou= t any performance gains, especially startup/reboot time, for OpenZFS via EB= S? The usual ZFS advantages of versioning/ZFS snapshots and the ability to s= tream updates seem attractive to our way of running our (growing) server far= m. I was just reading the current issue of the FreeBSD Magazine and I have f= ound out that ScaleEngine use OpenZFS in their AWS set-up. As an aside, the EFS is pretty slow=E2=80=94I suppose I had higher expectati= ons, considering EBS performance. I do not think that has much to do with Fre= eBSD and more likely a limitation of AWS NFS, but I wonder if there is anyth= ing on the horizon that could improve it. On another note, will the >32 bit N= FS log spam disappear anytime soon, ie. when is FreeBSD likely to get 64-bit= handles? Many thanks for your thoughts and my regards from Ireland, Rafal Lukawiecki Data Scientist Project Botticelli Ltd
