Description

This was observed in this e2e test failure: https://tracker.ceph.com/issues/47742

Some context about this e2d test:
- We need additional disks to test cephadm OSD creation feature. Because there are no sparse disks on smithi node:
- 3 sparse files are created and exported as iSCSI target luns (LIO).
- Login the target, 3 disks appear on host.
- Dashboard then ask cephadm to create 3 new OSDs with these disks.

The lvcreate command asks for one more extent (3838 vs 3839 in this example).
