I have a small 3 node ceph cluster with 6 OSDs on each node I would like to re-export some rbd images via LIO. Is it recommended to run RBD/LIO on one of the cluster nodes?
Preliminary tests show that it works fine. I have seen reports (that I can't find) that it is not recommended to run the RBD kernel module on an OSD node. Has anyone used multiple hosts to do iSCSI multipathing to a singe RBD image for vmware? My thoughts are to export the same RBD image via LIO from 2 hosts. It is easy to configure LIO to use the same iSCSI target address on both hosts. I could then configure vmware storage with the two ceph nodes as a primary/secondary failover.
