(I hope this post is not redundant I still seem to be having some troubles posting to this group and I'm using gmane) Hello one and all, I am suppose to be able to post to this group via gmane, but I'm not seeing the postings via gmane: http://news.gmane.org/gmane.comp.file-systems.ceph.user Maybe my application to this group did not get processed? Long version (hopefully more clear)? I want a distributed, heterogeneous cluster, without Hadoop. Spark (in-memory) processing [1] of large FEM [2] (Finite Element [math] Methods) is the daunting application that will be used in all sorts of scientific simulations with very large datasets. This will also include rendering some very complex 3D video/simulations of fluid type flows [3]. Hopefully the simulations will be computed and rendered in real time (less that 200ms of latency). Surely other massive types of scientific simulations can benefit from Spark/mesos/cephfs/btrfs, imho. Also being able to use the cluster for routine distcc compilations, Continuous Integration [4], log file processing, security scans and most other forms of routine server usage as of keen interest too. Eventually, the cluster(s) will use both the GPUs, x64 and the new Arm_64 bit processors, all with as much ram as possible. This is a long journey, but I believe that cephfs on top of btrfs will eventually mature into the robust solution that is necessary. The other portions of the solution like Distribute Features (Chronos, ansible/puppet/chef, DB etc etc will also be needed, but there does seem to be an abundance of choices for those needs; so discussion is warmly received in these areas too, as they relate to cephfs/btrfs. Cephfs on top of Btrfs is the most challenging part of this journey so far. I use openrc on gentoo, and have no interest in systemd, just so you know.
