VGSCAN(8)						      System Manager's Manual							 VGSCAN(8)

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

NAME

       vgimport - make volume groups known to the system

SYNOPSIS

       vgimport [-d|--debug] [-f|--force] [-h|--help] [-v|--verbose] VolumeGroupName PhysicalVolumePath [PhysicalVolumePath...]

DESCRIPTION

       vgimport  allows  you  to  make a volume group known to the system which has previously been exported (see vgexport(8) ) on this or another
       system.

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

       -f, --force
	      Force import of volume group even though it is not flagged exported.  This option allows the importing of volume groups from  broken
	      systems.

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

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

Examples
       "vgimport  myvg	/dev/sd[b-h]5"	tries to make new volume group "myvg" known to the system. The previously exported volume group (see vgex-
       port(8) ) resides on disk partitions "/dev/sdb5" to "/dev/sdh5".

DIAGNOSTICS

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

       1  no volume group name on command line
       2  invalid volume group name
       3  no physical volume(s) on command line
       4  volume group already exists
       5  physical volume occurs mutiple times on command line
       6  invalid physical volume name
       7  error reading physical volume
       8  physical volume is not exported
       9  error reallocating memory
       10 error allocating memory
       11 no valid physical volumes found
       12 physical volume belongs to a different exported volume group
       13 wrong number of physical volumes
       14 error reading VGDA from disk(s)
       15 VGDA is inconsistent
       16 invalid logical volume count
       17 error getting a free volume group number
       18 error writing VGDA to physical volumes
       19 error creating VGDA in kernel
       20 error inserting volume group into lvmtab
       21 error doing backup of VGDA to disk
       22 error storing VGDA in lvmtab
       23 not enough free logical volume manager block specials available

       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

Example
       "vgimport this_import /dev/sdk3 /dev/sdj4" tries to import a volume group contained on both partitions. The volume  group  this_import  may
       not already exit. You have to specify all physical volumes belonging to the exported volume group.
