Each OSD is 8GB? You need to make them at least 10 GB. Ceph weights each disk as it's size in TiB, and it truncates to two decimal places. So your 8 GiB disks have a weight of 0.00. Bump it up to 10 GiB, and it'll get a weight of 0.01. You should have 3 OSDs, one for each of ceph0,ceph1,ceph2. If that doesn't fix the problem, go ahead and post the things Udo mentioned.
