For now, only 'raw+size' is supported and it's not possible to export/import with snapshots. The volume or snapshot is mapped using krbd and then the data is read via 'dd'.
Introducing an 'rbd' transport format might be feasible for more complete (i.e. with snapshots, incremental) transfer between two RBD storages. Fiona Ebner (5): rbd plugin: schema: document default value for 'krbd' setting export: redirect stdout to avoid any unrelated messages ending up in the export stream rbd plugin: factor out helper to check if volume already exists rbd plugin: implement volume import/export plugins: volume import: align size up to 1KiB Max Carrara (1): common: introduce common module src/PVE/CLI/pvesm.pm | 5 +- src/PVE/Storage/Common.pm | 54 +++++++++++++ src/PVE/Storage/Common/Makefile | 6 ++ src/PVE/Storage/LVMPlugin.pm | 4 +- src/PVE/Storage/Makefile | 2 + src/PVE/Storage/Plugin.pm | 4 +- src/PVE/Storage/RBDPlugin.pm | 135 ++++++++++++++++++++++++++++++-- 7 files changed, 202 insertions(+), 8 deletions(-) create mode 100644 src/PVE/Storage/Common.pm create mode 100644 src/PVE/Storage/Common/Makefile -- 2.39.5 _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
