[SOLVED] lvm-thin migration - if interrupted,deletes lv

[zima]

After hitting [stop] in the middle of migration, ct shows on the destination node but without data (no lv - in log we see twice that lv successfully removed)

Jun 17 11:48:10 starting migration of CT 130 to node 'dreadnought' (10.10.10.111)
Jun 17 11:48:10 copy mountpoint 'rootfs' (local-lvm:vm-130-disk-1) to node ' dreadnought'
Logical volume "vm-130-disk-1" created.
successfully created 'local-lvm:vm-130-disk-1'
Logical volume "vm-130-disk-1" successfully removed
Logical volume "vm-130-disk-1" successfully removed
Jun 17 11:48:37 start final cleanup
Jun 17 11:48:38 migration finished successfully (duration 00:00:28)
TASK OK



lvs output on both nodes:
vm-101-disk-1 pve Vwi-a-tz-- 20.00g data 98.45
vm-134-disk-1 pve Vwi-a-tz-- 50.00g data 3.96

vm-133-disk-1 pve Vwi-a-tz-- 50.00g data 4.05

no 130 lv
