Hello,
Trying out Ceph for the first time, following the installation guide using ceph-deploy. All goes well, "ceph -s" reports health as ok at the beginning, but shortly after it shows all placement groups as inactive, and the 2 osds are down and out.
I understand this could be for a variety of reasons. Quick question, I've read on another mail that you have to manually mount the partitions on reboot and that this is not mentioned on the guide. I am testing this on a cloud provider and I wanted to test Ceph with 2 servers on the local filesystem e.g. I just created folders under /var/local/osd0 as in the tutorial without attaching a storage volume to the host and mounting it. Is this possible, or does Ceph always require partitions to be used for osds?
That would be a reason causing this failure.
Cheers
Dimitris
