Issue

Description of problem: Unable to complete or abort pvmove migration when it failed with error ' Logical volume vg00/pvmove0_mimage_0 in use.' pvmove --abort Internal error: Wrong params for _copy_poll_operation_id. Version-Release number of selected component (if applicable): Red Hat Enterprise Linux 9 uname -r ; rpm -q lvm2 5.14.0-284.11.1.el9_2.x86_64 lvm2-2.03.17-7.el9.x86_64 How reproducible: Always Steps to Reproduce: 1. Create a Volume Group and logical volume with multiple PVs. 2. Start migration using pvmove 3. Try to access the pvmove image (pvmove0_mimage_0/1) and keep it as busy/open while pvmove is in progress. 4. After moving all PEs, it failed with the error "LVM command executed by lvmpolld failed." Actual results: pvmove migration failed and was unable to remove the pvmove segments. >> Below is my lvm stack and I trying to migrate PEs from sda to sdc. lvs -ao +devices vg00 LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert Devices lv00 vg00 wi-ao--- 3.50g /dev/sda(0) lv01 vg00 wi-a---- 1.00g /dev/sda(896) lvol0 vg00 wi-a---- 3.00g /dev/sdb(0) >> Start migration using pvmove and try to open the device. pvmove --atomic /dev/sda /dev/sdc /dev/sda: Moved: 0.78% /dev/sda: Moved: 100.00% LVM command executed by lvmpolld failed.

Expected results: Looking for some options to clear the leftover pvmove segments properly even after failing the migration. Additional info: pvmove0_mimage_0/1 can be removed using lvremove, but the hidden "pvmove0" device can't change.
