I increased the OSDs to 10.5GB each and now I have a different issue...
cephy@ceph-admin0:~/ceph-cluster$ echo {Test-data} > testfile.txt
cephy@ceph-admin0:~/ceph-cluster$ rados put test-object-1 testfile.txt --pool=data
error opening pool data: (2) No such file or directory
cephy@ceph-admin0:~/ceph-cluster$ ceph osd lspools
0 rbd,
Here's ceph -w:
cephy@ceph-admin0:~/ceph-cluster$ ceph -w

Any other commands to run that would be helpful? Is it safe to simply manually create the "data" and "metadata" pools myself?

Aha, excellent suggestion! I'll try that as soon as I get back, thank you.

They have between 10% and 30% disk utilization but common between all of them is that they have free disk space meaning I have no idea what the heck is causing Ceph to complain.
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.
