Adding nodes, NSDs, or file systems to an existing installation

Use this information to add nodes, NSDs, or file systems to an installation process using the installation toolkit.

• To add nodes to an existing installation, do the following.
  1. Add one or more node types using the following commands.
     • Client nodes:

       ./spectrumscale node add FQDN

     • NSD nodes:

       ./spectrumscale node add FQDN -n 

     • Protocol nodes:

       ./spectrumscale node add FQDN -p

     • GUI nodes:

       ./spectrumscale node add FQDN -g -a

     For the list of supported node types that can be added, see spectrumscale command.
  2. Install GPFS on the new nodes using the following commands.

     ./spectrumscale install --precheck
     ./spectrumscale install

  3. If protocol nodes are being added, deploy protocols using the following commands.

     ./spectrumscale deploy --precheck
     ./spectrumscale deploy

• To add NSDs to an existing installation, do the following.
  1. Verify that the NSD server connecting this new disk runs an OS compatible with the installation toolkit and that the NSD server exists within the cluster.
  2. Add NSDs to the installation using the following command.

     ./spectrumscale nsd add -p FQDN_of_Primary_NSD_Server Path_to_Disk_Device_File

  3. Run the installation using the following commands.

     ./spectrumscale install --precheck
     ./spectrumscale install

• To add file systems to an existing installation, do the following.
  1. Verify that free NSDs exist and that they can be listed by the installation toolkit using the following commands.

     mmlsnsd
     ./spectrumscale nsd list

  2. Define the file system using the following command.

     ./spectrumscale nsd modify NSD -fs File_System_Name

  3. Deploy the file system using the following commands.

     ./spectrumscale deploy --precheck
     ./spectrumscale deploy
