While file-based network storages already can rely on the default file-based implementation in Plugin.pm, RBD and iSCSI plugins did not have the functionality yet. Regarding RBD: For now, only 'raw+size' is supported and it's not possible to export/import with snapshots. The volume or snapshot is mapped using rbd 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. For iSCSI plugins, remote migration will still fail further up the stack though: > can't migrate local disk 'iscsidirect:lun0': owned by other VM (owner = VM ) > can't migrate local disk 'iscsi:0.0.0.scsi-360014055b29367fb79a46b0bdb179fae': owned by other VM (owner = VM ) pve-storage: Fiona Ebner (10): plugin: export/import: fix calls to path() method 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 rbd plugin: improve volume exists helper iscsi plugin: support volume export iscsi direct plugin: support volume export plugins: volume import: align size up to 1KiB rbd plugin: list: drop outdated error message check Max Carrara (1): common: introduce common module src/PVE/CLI/pvesm.pm | 5 +- src/PVE/Storage/Common.pm | 54 ++++++++++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/ISCSIDirectPlugin.pm | 63 ++++++++++++ src/PVE/Storage/ISCSIPlugin.pm | 48 +++++++++ src/PVE/Storage/LVMPlugin.pm | 4 +- src/PVE/Storage/Makefile | 2 + src/PVE/Storage/Plugin.pm | 12 ++- src/PVE/Storage/RBDPlugin.pm | 142 ++++++++++++++++++++++++--- 9 files changed, 317 insertions(+), 19 deletions(-) create mode 100644 src/PVE/Storage/Common.pm create mode 100644 src/PVE/Storage/Common/Makefile pve-container: Fiona Ebner (2): migration: allow rbd storages for remote migration migration: add reminder to evaluate dropping seemingly useless check for PVE 9 src/PVE/LXC/Migrate.pm | 3 +++ 1 file changed, 3 insertions(+) Summary over all repositories: 10 files changed, 320 insertions(+), 19 deletions(-) -- Generated by git-murpp 0.5.0 _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
