7.1 NLVM Commands Quick Reference for Linux Volumes

Use this section as a quick reference for the NLVM commands that support Linux POSIX volumes. Enter commands in a terminal console or script as the root user. For details about each command, see the OES 2023: NLVM Reference.

Task

Command

Create a clustered Linux LVM volume group and logical volume.

Specify the ncp option to enable NCP for the volume and create an NCP share at the root of the volume, and to automatically create the NCP Server storage object for the cluster resource.

See also Section 8.0, Clustering LVM Volume Groups with Novell Cluster Services.

 
nlvm create linux volume 
  type=<btrfs|ext2|ext3|reiserfs|xfs> 
  device=<devicename>
  mp=<full_mount_point_path>
  [mntopt=<fs_mount_options>] 
  lvm
  name=<lv_name> 
  [group=<vg_name>]
  shared
  ip=<resource_ip_address>
  [ncp]

Example: 

nlvm create linux volume 
   type=xfs 
   device=sde 
   mp=/mnt/vol42 
   mntopt=rw 
   lvm 
   name=lvmvol42 
   shared 
   ip=10.10.10.42

Create a Linux LVM volume group and logical volume.

Specify the ncp option to enable NCP for the volume and create an NCP share at the root of the volume.

See also Creating an LVM Logical Volume.

 
nlvm create linux volume 
  type=<btrfs|ext2|ext3|reiserfs|xfs
  device=<devicename>
  size=<value[K|M|G|T]>
  mp=<full_mount_point_path>
  [mntopt=<fs_mount_options>] 
  lvm
  name=<lv_name> 
  [group=<vg_name>]
  [ncp]

Example: 

nlvm create linux volume 
   type=xfs 
   device=sde 
   size=511M 
   mp=/mnt/vol42 
   mntopt=rw 
   lvm 
   name=lvmvol42 
   group=lvmvg42

Create a Linux POSIX volume.

Specify the ncp option to enable NCP for the volume and create an NCP share at the root of the volume.

See also Creating a Non-LVM Linux Volume.

 
nlvm create linux volume 
  type=<btrfs|ext2|ext3|reiserfs|xfs> 
  device=<device_name|anydisk> 
  size=<value[K|M|G|T]|max>
  mp=<full_mount_point_path>
  [mntopt=<fs_mount_options>] 
  [ncp]

Example: 

nlvm create linux volume 
   type=ext3 
   device=sda 
   size=20G 
   mp=/mnt/vol1 
   mntopt=rw
