[iscsidirectplugin.pm, common.pm, lvmplugin.pm, rbdplugin.pm, plugin.pm, iscsiplugin.pm, pvesm.pm] Subject: [pve-devel] [PATCH v2 storage 00/10] import/export for shared storages X-BeenThere: pve-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox VE development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Reply-To: Proxmox VE development discussion Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: pve-devel-bounces@lists.proxmox.com Sender: "pve-devel" Changes in v2: * add fix for path() in iSCSI direct plugin * add export for iSCSI plugins * add RFC for improving RBD volume exists helper For remote migration, export/import functionality is also useful for storages that are shared within a single cluster. 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 ) Fiona Ebner (9): iscsi direct plugin: fix return value for path() method in non-array context 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 iscsi plugin: support volume export iscsi direct plugin: support volume export rbd plugin: volume exists helper: distinguish between different errors 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/ISCSIDirectPlugin.pm | 65 ++++++++++++- src/PVE/Storage/ISCSIPlugin.pm | 48 +++++++++ src/PVE/Storage/LVMPlugin.pm | 4 +- src/PVE/Storage/Makefile | 2 + src/PVE/Storage/Plugin.pm | 4 +- src/PVE/Storage/RBDPlugin.pm | 139 ++++++++++++++++++++++++++- 9 files changed, 318 insertions(+), 9 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
