[--commandprofile ProfileName] [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--mknodes]
[-P|--partial] [-v|--verbose]
vgscan scans all SCSI, (E)IDE disks, multiple
devices and a bunch of other disk devices in the system looking for LVM
physical volumes and volume groups. Define a filter in lvm.conf(5)
to restrict
the scan to avoid a CD ROM, for example.
In LVM2, vgscans take place automatically;
but you might still need to run one explicitly after changing hardware.
See lvm(8)
for common options.
- --mknodes
- Also checks the LVM special
files in /dev that are needed for active logical volumes and creates any
missing ones and removes unused ones.
- --cache
- Scan devices for LVM physical
volumes and volume groups and instruct the lvmetad daemon to update its
cached state accordingly.
