You can use the nlvm delete linux volume command to delete a Linux POSIX volume. The volume must be unmounted. For command usage information, see Delete Linux Volume
in the OES 2023: NLVM Reference.
WARNING:The delete process removes the partition for the volume, and destroys all of the data on the partition.
Log in to the server as the root user, then open a terminal console.
View a list of Linux volumes by entering the following command, then find the name, mount point, and mount status of the volume that you want to delete.
nlvm list linux volumes
For example, the following Linux POSIX volume’s name is /vol1. Its mount point is /mnt/vol1. Its mount status is Mounted.
nlvm list linux volumes Name Group Mounted Size Shared Type LVM NCP Mountpoint / Yes 15.98GB No ext3 No No / /boot Yes 297.00MB No ext2 No No /boot /home Yes 403.00GB No ext3 No No /home /vol1 Yes 25.98GB No ext3 No No /mnt/vol1 VOL2 Yes 19.98GB No ext3 No Yes /mnt/VOL2
Dismount the volume by entering the native Linux umount command:
umount <full_mount_point_path>
Replace full_mount_point_path with the volume’s mount point. For example, enter
umount /mnt/vol1
Delete the Linux POSIX volume by entering
nlvm [--no-prompt] delete linux volume <volume_name>
You are automatically prompted to confirm the delete action. Enter yes to continue or enter no to cancel. Use the --no-prompt NLVM option to suppress the confirmation.
For example, enter
nlvm delete linux volume /vol1
Verify that the volume no longer appears in the list of Linux volumes by entering
nlvm list linux volumes
The volume does not appear in the list.

Verify that the space used by the volume’s partition is now available as free unpartitioned space by entering
nlvm list devices
For example, see the Size, Used, and Free values for the device, such as for sdd:
nlvm list devices Name Size Used Free Format Shared RAID Enabled sda 11.00GB 9.29GB 1.70GB MSDOS No No sdb 102.00MB 102.00MB 0KB MSDOS Yes No sdc 102.00MB 102.00MB 0KB MSDOS Yes No sdd 512.00MB 16KB 511.98MB MSDOS No No
Use the procedure in this section to delete an LVM volume group and logical volume. If the LVM volume group and logical volume are clustered with Novell Cluster Services, use the instructions in Deleting a Clustered LVM Volume Group and Logical Volume.
Log in to the server as the root user, then open a terminal console.
View a list of Linux volumes by entering the following command, then find the name, mount point, and mount status of the volume that you want to delete.
nlvm list linux volumes
For example, the following LVM logical volume’s name is lvvol1. Its mount point is /mnt/lvvol1. Its mount status is Mounted.
nlvm list linux volumes Name Group Mounted Size Shared Type LVM NCP Mountpoint / Yes 15.98GB No ext3 No No / /boot Yes 297.00MB No ext2 No No /boot /home Yes 403.00GB No ext3 No No /home lvvol1 Yes 25.98GB No ext3 No No /mnt/lvvol1 VOL2 Yes 19.98GB No ext3 No Yes /mnt/VOL2
Dismount the volume by entering the native Linux umount command:
umount <full_mount_point_path>
Replace full_mount_point_path with the volume’s mount point. For example, enter
umount /mnt/lvvol1
Delete the LVM logical volume and its volume group by entering
nlvm delete linux volume <lv_name>
You are automatically prompted to confirm the delete action. Enter yes to continue or enter no to cancel. Use the --no-prompt NLVM option to suppress the confirmation.
For example, enter
nlvm delete linux volume lvvol1
Verify that the volume no longer appears in the list of Linux volumes by entering

Verify that the LVM volume group is deleted by entering the native LVM vgdisplay command:
vgdisplay
Verify that the space used by the volume group’s partition is now available as free unpartitioned space by entering
nlvm list devices
For example, see the Size, Used, and Free values for the device, such as for sdd:
