we're also using cinder from openstack ocata release.
the point is a) we didn't upgrade, but started from scratch with ceph 12 b) we didn't test all of the new features in ceph 12 (eg. EC pools for RBD devices) in connection with cinder yet
Thanks. We use EC pools with replication pull cache - only one way to use EC with rbd, before Ceph 12. We are half year on Ceph with oVirt in production. The best storage experience, the only thing you can find fault this is impossible to move images between pools. Only manually migration with qemu-img/rados or cp/rsync inside VM. -- Best regards, Konstantin Shalygin --------------F21CBAF3CD53691C26FFFE99 Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: 7bit <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> </head> <body bgcolor="#FFFFFF" text="#000000"> On 10/25/2017 03:30 PM, Matthias Leopold wrote:<br> <blockquote type="cite" cite="mid:46bcd7a5-1739-7117-12a5-80c85f8f4035@meduniwien.ac.at">we're also using cinder from openstack ocata release. <br> <br> the point is <br> a) we didn't upgrade, but started from scratch with ceph 12 <br> b) we didn't test all of the new features in ceph 12 (eg.
