It’s entirely possible — and documented — to mirror individual images. Your proposal to use snapshots is reinventing the wheel, but with less efficiency. https://docs.ceph.com/docs/nautilus/rbd/rbd-mirroring/#image-configuration ISTR that in Octopus the need for RBD journals is gone, but am not positive. For done 1-2 volumes at a time you’ll want to increase two tunables to avoid protracted syncing. Without these I’ve experienced a volume of just a few TB take multiple hours to converge, and some that got increasingly behind over time. rbd_mirror_journal_max_fetch_bytes: section: "client" value: "33554432" rbd_journal_max_payload_bytes: section: "client" value: "8388608" > On May 14, 2020, at 12:23 AM, Kees Meijs <kees@xxxxxxxx> wrote: > > I need to mirror single RBDs while rbd-mirror: "mirroring is configured > on a per-pool basis" (according documentation). > > On 14-05-2020 09:13, Anthony D'Atri wrote: >> So? > _______________________________________________ > ceph-users mailing list -- ceph-users@xxxxxxx > To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
