Ceph: fix active+undersized+degraded pgs after removing an osd?
I can't find clear information anywhere. How to make Ceph cluster healthy again after osd removing? I just removed one of the 4 osd. Deleted as in manual.

I'm not familiar with rook, but apparently the rulesets are created for you? Anyway, they all use "host" as failure-domain and have a size of 3, but with only two hosts your requirements can not be fullfilled. I assume the 4th OSD you had was on a third host, that's why your cluster is now degraded. You'll need to add at least one more host so your PGs can recover successfully. As for the erasure-coded pool it also has "host" as failure-domain, and with size = 3 (I assume the EC profile is something like k=2, m=1 ?) you also require 3 hosts. To get the replicated pools recovered you could change their size to 2, but I don't recommend to do that permanently, only for recovery reason. Since you can't change an EC profile that pool will stay degraded until you add a third OSD node. To answer your other questions:
- Failure domain: It really depends on your setup, it could be rack, chassis, data center and so on. But with such a tiny setup it makes sense to have "host" as the failure domain.
- Ceph is a self-healing software, so in case an OSD fails Ceph is able to recover automatically, but only if you have enough spare hosts/OSDs. So with your tiny setup you don't have enough capacity to be resilient against at least one OSD failure. If you plan to use Ceph for production data you should familiarize yourself with the concepts and plan a proper setup.
- The more OSDs per host the better, you'll have recovery options. Warnings are fine, in case Ceph notices a disk outage it warns you about it, but it is able to recover automatically if there are enough OSDs and hosts.
If you look at the output of
ceph osd treethere are only 2 hosts with three OSDs, that's why it's not fine at the moment.
