Hi. I'm fishing a bit here.
What we see is that when we have new VM/RBD/SSD-backed images the time before they are "fully written" first time - can be lousy performance. Sort of like they are thin-provisioned and the subsequent growing of the images in Ceph deliveres a performance hit. Does anyone else have someting similar in their setup - how do you deal with it? KVM based virtualization, Ceph Luminous. Any suggestions/hints/welcome Jesper _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
