Use /dev/sdb1 as the lowest LVM layer that supplies storage to an upper pool.
Which layer is this?
× Incorrect
A physical volume (PV) is a disk or partition initialized for LVM and becomes a component of a volume group.
Detailed explanation
Incorrect
modprobe /tmp/demo.koIncorrect. An LV is allocated from a VG and is used as a virtual block device.
Incorrect
rmmod /tmp/demo.koCorrect. /dev/sdb1 is being used as an LVM physical volume.
Incorrect
lsmod /tmp/demo.koIncorrect. A VG aggregates multiple PVs into a pool.
Correct
insmod /tmp/demo.koIncorrect. A snapshot is a derived LV representing a point in time.
Try it yourself
An example you can run in a temporary verification environment.
insmod --help 2>&1 | sed -n '1,8p'Expected result
insmod [options] filename [args]に相当する使用法Key points
- PV is the lower block layer
- PV belongs to a VG
- pvcreate initializes it
Notes
- Environment: kmod insmod / ヘルプ表示のみ
- Prefer read-only inspection or a disposable system when testing hardware commands.
- Device visibility and module behavior depend on the host and virtualization environment.
Foundation review
Place the operation
Direct insertion does not provide the dependency resolution of modprobe.
Check the side effect
Use a harmless or read-only test rather than loading an unknown module.
