After # virsh vol-create a vol in a logical pool # virsh vol-delete --pool pool-logical-testing vol-logical-testing error: Failed to delete vol vol-logical-testing error: internal error '/sbin/lvremove -f /dev/pool-logical-testing/vol-logical-testing' exited with non-zero status 5 and signal 0: Can't remove open logical volume "vol-logical-testing" # virsh pool-destroy pool-logical-testing error: Failed to destroy pool pool-logical-testing error: internal error '/sbin/vgchange -an pool-logical-testing' exited with non-zero status 5 and signal 0: Can't deactivate volume group "pool-logical-testing" with 1 open logical volume(s) But, after umount the vol, # umount /tmp/logical-vol-mnt-testing Then, # virsh vol-delete --pool pool-logical-testing vol-logical-testing Vol vol-logical-testing deleted # virsh pool-destroy pool-logical-testing Pool pool-logical-testing destroyed This seems to be operating as designed. If you have mounted the logical volume as a filesystem, then clearly it is in use by the OS, so vol-delete is expected to fail. |
Description of problem: we need to focus on the following designing of the libvirt: 1.can get volume object if and only if storage pool is active 2.may remove storage volume if and only if storage pool is inactive it seems conflict, when we destroy stroage pool, we can't get volume object, hence,we can't also call volume object method of 'delete',finally, we can't remove the logical volume.
