I’m looking at cranking up a home lab (three hosts/nodes) using Clear, Ceph and KVM/QEMU. I have some questions that I’m hoping someone can provide insight into.
- When installing Clear Linux onto the bare metal hosts SSD’s, can Clear’s own partitions (inc root) be setup on Ceph directly?
(I have a fourth host that I can use to setup Ceph on the three primary hosts for the cluster in advance)
1b. If not, does the Clear OS need to sit on it’s own Raid 1 SSD’s (with xfs or ext4 etc) so that it’s isolated from the disks of the Ceph pool running within the same hosts?
- Is there a recommended (/suggestions for an) orchestration tool for VM management that can support live migration (ideally HA automated fail over, doesn’t need full fault tolerance lock step) of VM’s running on the Clear Linux hosts in KVM/QEMU?
(assume the storage layer to be equally available to all the Clear host via the Ceph storage pool they’re running).
I’m coming at this as a learning project, from a VMWare and oVirt background. I’m not expecting anything as polished as those solutions.
