Only migrate images referenced in the config. This made it necessary to handle pending changes explicitly which had been covered by the storage scan. We also added checks for any aliased volids and fail the migration if detected. The qemu-server part consists of quite a lot more commits since we had to change a few things and for a better history, they are mostly their own patches. There is also a small patch for the documentation to add a hint that aliased storages should be avoided. changes since v3: - drop patch 4/12 rest regular config last - refactor test_volid and ref handling -> is_attached - reorder patches, first volid_changes reg. pending disks, then the change in migration storage scanning - rebase as 5/12 is already applied v3: - split it into many smaller commits - changed / improved the handling of the 'ref's in QemuMigrate::scan_local_volumes() - fixed tests and added error handling in new mock functions - rephrased the documentation hint v2: - style fixes - qemu-server: mainly change the handling of pending changes - container: use NEW_DISK_RE to check if the volume is a not yet created pending volume More in each patch. qemu-server: Aaron Lauterer (7): qemuserver: foreach_volid: include pending volumes qemuserver: foreach_volid: always include pending disks migration: only migrate disks used by the guest qemuserver: migration: test_volid: change attr name and ref handling tests: add migration test for pending disk migration: fail when aliased volume is detected tests: add migration alias check PVE/QemuMigrate.pm | 82 +++++--------- PVE/QemuServer.pm | 19 +++- test/MigrationTest/QemuMigrateMock.pm | 10 ++ test/run_qemu_migrate_tests.pl | 151 +++++++++++++++++++++++++- 4 files changed, 198 insertions(+), 64 deletions(-) container: Aaron Lauterer (2): migration: only migrate volumes used by the guest migration: fail when aliased volume is detected src/PVE/LXC/Migrate.pm | 51 +++++++++++++++++------------------------- 1 file changed, 21 insertions(+), 30 deletions(-) docs: Aaron Lauterer (1): storage: add hint to avoid storage aliasing pvesm.adoc | 6 ++++++ 1 file changed, 6 insertions(+) -- 2.39.2
