Centos 7/8/9 and openeuler build fail with /usr partition while works for other distro

[Peter Garlic]

Using /usr on partition schema image build fails with error "Logical volume vg/lv_root contains a filesystem in use"

After the error program loops on " umount: /tmp/dib_image.nnnnnnn: target is busy."

Error tested and found with: centos 7, 8 , 9, openeuler-minimal
The same configuration works with: ubuntu 20 (focal), debian 11 (bullseye), opensuse 15.1

Test environment:
build server: Fedora release 31 (Thirty One)
disk-image-create: 3.16.1
Python: 3.7.9

Below the exception snippet, full log for centos7 (same error for version 8, 9 and openeuler) on attachment:
