NAME

       vgexport - make volume groups unknown to the system

SYNOPSIS

       vgexport [-a|--all] [-d|--debug] [-h|--help] [-v|--verbose] [--version] [VolumeGroupName...]

DESCRIPTION

       vgexport allows you to make the inactive VolumeGroupName unknown to the system.	You can then move all of the physical volumes in that vol-
       ume group to a different system for later vgimport(8).  An exported volume group is not detected by  vgscan(8),	but  pvscan(8)	will  show
       which physical volumes belong to the exported volume group.

   OPTIONS
       -a, --all
	      Exports all inactive volume groups.

       -d, --debug
	      Enables additional debugging output (if compiled with DEBUG).

       -h, --help
	      Print a usage message on standard output and exit successfully.

       -v, --verbose
	      Display verbose runtime information about vgexport's activities.

       --version
	      Display tool and IOP version and exit successfully.

DIAGNOSTICS

       vgexport returns an exit code of 0 for success and > 0 for error:

       1  no volume groups found at all
       2  no volume group name on command line

       95 driver/module not in kernel
       96 invalid I/O protocol version
       97 error locking logical volume manager
       98 invalid lvmtab (run vgscan(8))
       99 invalid command line

NAME

       vgscan - scan all disks for volume groups and build /etc/lvmtab and /etc/lvmtab.d/* which are the database for all other lvm commands.

SYNOPSIS

       vgscan [-d|--debug] [-f|--forcenumbers] [-h|--help] [-r|--remove_snapshots [VolumeGroupName]] [-v|--verbose]

DESCRIPTION

       vgscan scans all SCSI, (E)IDE disks, multiple devices and a bunch of other disk devives in the system for volume groups defined.

   OPTIONS
       -d, --debug
	      Enables additional debugging output (if compiled with DEBUG).

       -f, --forcenumbers
	      If  used	volume group and/or logical volume minor numbers are found during scan, replace them. This will potentially cause problems
	      for NFS exported filesystems on logical volumes with changed numbers.

       -h, --help
	      Print a usage message on standard output and exit successfully.

       -r, --remove_snapshots [VolumeGroupName]
	      Remove all snapshot logical volumes from all or just the named volume group.

       -v, --verbose
	      Display verbose information of vgscan's activities.

Hint
       Put vgscan in one of your system startup scripts.  This gives you an actual logical volume manager database before  activating  all  volume
       groups by doing a "vgchange -ay".

DIAGNOSTICS

       vgscan returns an exit code of 0 for success and > 0 for error:

       1  error reading physical volumes
       2  error inserting vokume group name into lvmtab
       3  no volume group(s) found
       4  error creating lvmtab
       5  no or not enough free device specials to store volume group in lvmtab
       6  error storing VGDA on disk(s)
       7  reused LV device number
       8  error releasing snapshot logical volume

       95 driver/module not in kernel
       96 invalid I/O protocol version
       97 error locking logical volume manager
       99 invalid command line
