pvchange - change attributes of a physical volume SYNOPSIS
pvchange [-A|--autobackup {y|n}] [-d|--debug] [-h|--help] [-v|--verbose] [-a|--all] [-x|--allocation {y|n}] [PhysicalVolumePath...] DESCRIPTION
pvchange allows you to change the allocation permissions of one or more physical volumes. OPTIONS -A, --autobackup y/n Controls automatic backup of VG metadata after the change ( see vgcfgbackup(8) ). Default is yes. -d, --debug Enables additional debugging output (if compiled with DEBUG). -h, --help Print a usage message on standard output and exit successfully. -v, --verbose Gives verbose runtime information about pvchange's activities. -a, --all If PhysicalVolumePath is not specified on the command line all physical volumes are searched for and used. -x, --allocation y/n Enable or disable allocation of physical extents on this physical volume. Example "pvchange -x n /dev/sdk1" disallows the allocation of physical extents on this physical volume (possibly because of disk errors, or because it will be removed after freeing it. DIAGNOSTICS
pvchange returns an exit code of 0 for success and > 0 for error: 1 no physical volume name(s) on command line 2 no physical volume names found 3 error changing physical volume in kernel 4 error writing physical volume 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 ENVIRONMENT VARIABLES
LVM_AUTOBACKUP If this variable is set to "no" then the automatic backup of VG metadata is turned off. LVM_VG_MAX_BACKUPS This variable determines the backup history depth of kept VGDA copy files in /etc/lvmconf. It can be set to a positive number between 0 and 999. The higher this number is, the more changes you can restore using vgcfgrestore(8). See also lvm(8), pvcreate(8), pvmove(8) AUTHOR

VGEXTEND(8) System Manager's Manual VGEXTEND(8) NAME
vgextend - add physical volumes to a volume group SYNOPSIS
vgextend [-A|--autobackup{y|n}] [-d|--debug] [-h|--help] [-v|--verbose] VolumeGroupName PhysicalVolumePath [PhysicalVolumePath...] DESCRIPTION
vgextend allows you to add one or more initialized physical volumes ( see pvcreate(8) ) to an existing volume group to extend it in size. OPTIONS -A, --autobackup y/n Controls automatic backup of VG metadata after the change ( see vgcfgbackup(8) ). Default is yes. -d, --debug Enables additional debugging output (if compiled with DEBUG). -h, --help Print a usage message on standard output and exit successfully. -v, --verbose Gives verbose runtime information about lvextend's activities. Examples "vgextend vg00 /dev/sda4 /dev/sdn1" tries to extend the existing volume group "vg00" by the new physical volumes (see pvcreate(8) ) "/dev/sdn1" and /dev/sda4". DIAGNOSTICS
vgextend returns an exit code of 0 for success and > 0 for error: 1 no volume group name on command line 2 volume group name not given as first argument 3 no physical volume(s) on command line 4 invalid volume group name 5 error checking existence of volume group 6 inactive volume group 7 error reading VGDA 8 volume group is set to not extendable 9 maximum physical volume number of volume group exceeded 10 error reading all physical volumes 11 error setting up VGDA 12 error extending VGDA in kernel 13 error writing VGDA to physical volume(s) 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 ENVIRONMENT VARIABLES
