lvm_deletelv Subroutine

Base Operating System and Extensions Technical Reference, Volume 1

lvm_deletelv Subroutine

Purpose

Deletes a logical volume from its volume group.

Library

Logical Volume Manager Library (liblvm.a)

Syntax

#include <lvm.h>

int lvm_deletelv (LV_ID)
struct lv_id *LV_ID;

Description

The lvm_deletelv subroutine deletes the logical volume specified by the LV_ID parameter from its volume group. The logical volume must not be opened, and the volume group must be online, or an error is returned. Also, all logical partitions belonging to this logical volume must be removed using the lvm_reducelv subroutine before the logical volume can be deleted.

Note: You must have root user authority to use this subroutine.

Parameters

LV_ID

Specifies the logical volume to be deleted.

Return Values

The lvm_deletelv subroutine returns a value of 0 upon successful completion.

Error Codes

If the lvm_deletelv subroutine fails, it returns one of the following values:

LVM_ALLOCERR	A memory allocation error occurred.
LVM_DALVOPN	The logical volume reserved by the volume group could not be opened.
LVM_FORCEOFF	The volume group has been forcefully varied off due to a loss of quorum.
LVM_INVALID_MIN_NUM	An invalid minor number was received.
LVM_INVALID_PARAM	The logical volume ID passed in is not a valid logical volume, or the pointer to the logical volume is invalid.
LVM_INVCONFIG	An error occurred while attempting to configure this volume group into the kernel. This error will normally result if the major number in the mapped file is invalid.
LVM_INV_DEVENT	The device entry for the logical volume is invalid and cannot be checked to determine if it is raw.
LVM_LVOPEN	An open logical volume was encountered when it should be closed.
LVM_MAPFBSY	The volume group is currently locked because system management on the volume group is being done by another process.
LVM_MAPFOPN	The mapped file, which contains a copy of the volume group descriptor area used for making changes to the volume group, could not be opened.
LVM_MAPFRDWR	An error occurred while trying to read or write the mapped file.
LVM_NODELLV	The logical volume cannot be deleted because there are existing logical partitions.
LVM_NOTCHARDEV	The device specified is not a raw or character device.
LVM_OFFLINE	A routine that requires a volume group to be online has encountered one that is offline.

Implementation Specifics

This subroutine is part of Base Operating System (BOS) Runtime.
