We are using Ceph+RBD+NFS under pacemaker for VMware. We are doing iSCSI using SCST but have not used it against VMware, just Solaris and Hyper-V.
It generally works and performs well enough – the biggest issues are the clustering for iSCSI ALUA support and NFS failover, most of which we have developed in house – we still have not quite got that right yet.

There's been quite a few VMWare/Ceph threads on the mailing list in the past. One setup I've been toying with is a linux guest running on the vmware host on local storage, with the guest mounting a ceph RBD with a filesystem on it, then exporting that via NFS to the VMWare host as a datastore. Exporting CephFS via NFS to Vmware is another option. I'm not sure how well shared storage will work with either of these configurations. but they work fairly well for single-host deployments. There are also quite a few products that do support iscsi on ceph. Suse Enterprise Storage is a commercial one, PetaSAN is an open-source option.

I know that openstack/cinder work well with ceph and proxmox (just heard) too. But currently we are using vmware and ovirt. Your wise suggestion is appreciated Cheers Joshua On Thu, Mar 1, 2018 at 3:16 AM, Mark Schouten <m...@tuxis.nl<mailto:m...@tuxis.nl>> wrote: Does Xen still not support RBD?

I was building ceph in order to use with iSCSI. But I just see from the docs that need: CentOS 7.5 (which is not available yet, it's still at 7.4) https://wiki.centos.org/Download Kernel 4.17 (which is not available yet, it is still at 4.15.7) https://www.kernel.org/ So I guess, there is no ufficial support and this is just a bad prank. Ceph is ready to be used with S3 since many years. But need the kernel of the next century to works with such an old technology like iSCSI. So sad. _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com<mailto:ceph-users@lists.ceph.com> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com<mailto:ceph-users@lists.ceph.com> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com<mailto:ceph-users@lists.ceph.com> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com Confidentiality: This email and any attachments are confidential and may be subject to copyright, legal or some other professional privilege.
