pvmove с ошибками

Решил перевести домашний файловый сервер на LVM2, перед переходом на целевой машине, решил провести тестирование LVM2 на виртуальной машине (vmware workstation), столкнулся с такой проблемой что при выполнении pvmove /dev/sdc1, на консоль выводится следующее:

/dev/sdc1: Moved: 40.0%

При этом ни в логах ни в dmesg не появляется никаких записей. В Volume Groupe, в которой находится phisical volume /dev/sdc1, достаточно свободных екстент для перемещения данных с /dev/sdc1 на них. При этом на первый взгляд перемещение происходит успешно, также это подтверждается сопоставлением контрольных сумм данных до перемещения и после. Если кто то сталкивался, подскажите пожалуйста с чем это может быть связанно, и не будет ли каких либо подводных камней.
