Anyone know why a VM live restore would be excessively slow on Ceph? restoring
a small VM with 12GB disk/2GB Ram is taking 18 *minutes*. Larger VM's can be
over half an hour.
The same VM's on the same disks, but native, or glusterfs take less than 30
seconds.
VM's are KVM on Proxmox.
Hi.
For faster operation, use rbd export/export-diff and import/import-diff
