[ceph-users] Re: Best way to add multiple nodes to a cluster?

Hi, I see 2 ways : Add your OSD with 0 weight, and slowly increase their weight or add OSD 1 by 1. It’s easy but “stupid” as some PG will move many times. Check https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/message/OKCWC5KNQF2FD3V4WI2IGMQBGOYY2LL2/

[ceph-users] Re: Best way to add multiple nodes to a cluster?

Zakhar; When adding nodes I usually set the following: noin (OSDs register as up, but stay out) norebalance (new placement shouldn't be calculated when the cluster layout changes, I've been bit by this not working as expected, so I also set below) nobackfill (PGs don't move) I then remove noin,
