Hello, I read in RHV 4.2 Beta release note that CEPH will be supported using iSCSI. I have tried to check community documentation regarding CEPH support but there was no luck. Do we have such document? Best regards, Ab

Yup, Gianluca is right. My bad to mention RHV 4.2 Beta release notes instead of CaptinKVM blog post " https://www.ovirt.org/documentation/vmm-guide/chap-Additional_Configuration/ " """

I'm afraid not. For oVirt, it's just another iSCSI target like any other iSCSI storage. Y.

ErrrWHAAAAAA??? If Ceph support is in oVirt, I am about to be extremely excited. I'm just racked the hardware for a new oVirt install today and the Ceph gear is showing up in a few weeks. I was planning on setting up a dedicated NFS server for VM's essentially having two storage domains, but if I can just have Ceph...I would be a very happy sys admin! ~Stack~ --JhsUm3ulU9R8r3VnILSgA7mHpoeqvooG6-- --BVhBAWU1RUa3tJNkgvP5j36uD98uCQjVq Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJaU/GNAAoJELkej+ysXJPmhKUQAKh8EJ4tejOx6KzYUpf6DOB9 FHblvB0cxtiMXx+Vr6NEwsKYfKhAvn1JC4KJFN7PzqpOHOPMqgqlTm0Lsn+EZIKN CpixxaAdIimgGwasdduih6ovmnyfvuZ9zBR50U4emx//AMr8urmlHZZyg38ksuTC LkR3z4jIwm9jNbb/FxN1RAux+9QjYZkKwPOa41YO2T6Fs4Gjh081C/r7LpCQRkxH YDXu8G9Qhdq0VK/lM1uHEqRc3x3wT8cM8iWwkzaIhjncHV2C34X/QsP3UIonTbIp P18sQUUm1efs95dc/wd1IguzLHveCtujVJOmNkYKZqug92o11NewPjkagcf3cKx8 CBjpMd/63E9IiTU6DDjCUDYxce7889t5wq7rSOCK4/u6gKkVe/NcZMRWibjPGuWz qfqPp3aDhG+kANr5+oE098nSq9ljPv63rjbvhewbJUVUBtEJf0WEzfi4V3h7xZ1G TgY6Bflj9RkbLAO7y23ye2NU7cOLWdPfly1+hXxapyIqz6cIaS5k9JxBT2fuqVQy mvXTnxkNitTyR4RqfMuGnPPlaCzRM9FOZzQVtOIQm4irmspAB3t6lGd/ATgXtk7o V7oGzfetnB36MblYtGCIy6GTobdUAcvKe2aN79Qu8lFUCy3R/9qTKu4U0KTHeV6i WEGldjl79bjlYXuKjf49 =jGwN -----END PGP SIGNATURE----- --BVhBAWU1RUa3tJNkgvP5j36uD98uCQjVq--

just for the records: we are running a productive oVirt 4.1 cluster with storage on a Ceph 12.2 cluster connected as an external provider, type: Openstack Volume (= Cinder) Matthias

Yup, but that's different than using iSCSI, since you're using directly qemu with librbd as storage module.

What is stopped you from start use ceph via librbd NOW? All you need is a OpenStack Cinder as volume manager wrapper. You can check librbd version of your hosts via oVirt manager (see attached sceenshot).

This is just usual iSCSI http://docs.ceph.com/docs/master/rbd/iscsi-overview/ k

Ceph is supported since 3.6 via Cinder. But the support is not complete, some features are not available with Ceph, mainly integration with other storage types, like moving disks to/from Ceph and other storage, live storage migration, image upload and download, and vm leases. But it may be good enough to keep you happy! Nir

I suppose they have tested ceph iscsi gateway http://docs.ceph.com/docs/master/rbd/iscsi-overview/ And they have certified as compatible. I don't really know why it shouldn't but the certification means that opening a SR to RH when using this setup will get the appropriate help.
