hi forum
we have 3 hosts in a running cluster. there is a seperate 10gbps storage network attached to all hosts.
each host have 2x 1tb ssd disks. out goal is a ha storage with 1 host failure tolerance.
is it better to to have a raid0 configuration on each host and attach this raid to one osd, or create one osd for each ssd?
and for pool, what are best settings for size / min size and pg_num?
for my understanding, size means replicas on different osds, right? but what means min size?
thanks in advance for any help.
regards,
daniel
