Hello again guys,
Can you recommend me a book that explains best practices with Ceph, for example is it okay to have mon,mgr, osd in the same virtual machine,
OSDs can need very much RAM during recovery, after crashes and things like that. In such a case, it might be suboptimal to cohost other services on that host, since those would be starved for memory if/when the OSD balloons to huge sizes for a short while. As for recommendations, this needs more information on what to achieve, what budget you have, what other choices one must make (OS, virtualization or not) and so on. There is no one single solution for "storage", not even just within ceph. -- May the most significant bit of your life be positive.
