yes, a raid1 system disk is necessary, from my perspective. And a swap partition is still needed even though the memory is big. Martin Palma <mar...@palma.bz<mailto:mar...@palma.bz>> 于 2015年9月18日，下午11:07写道：</span Hi,
Is it a good idea to use a software raid for the system disk (Operating System) on a Ceph storage node? I mean only for the OS not for the OSD disks. And what about a swap partition? Is that needed? Best, Martin
