Thanks for the info. I haven't tried the diskless build yet. Does it use nfsroot or only ramdisk? If it uses nfsroot, can you have multiple nfs server servicing different groups of nodes? Or can you build the root fs on a NAS (like a netapp) ?

Hi Mahmoud Unfortunately not all OCS users are as advanced as you are. The packages and custom scripts are typically added by ngedit, but adding them is basically just adding a database entry. Adding a custom script could be done by: 1. Copy the script you want to run to /depot/repos/custom_scripts 2. Get the nodegroup ID of the node group that should run this script # sqlrunner -q 'select ngid,ngname from nodegroups' The first column is the nodegroup ID 3. Add the script into the scripts table i.e. # sqlrunner -q 'insert into scripts set ngid={Your ngid}, script="{Your script name}"' Adding packages is a similiar process: 1. Get the nodegroup ID of the node group that should run this script # sqlrunner -q 'select ngid,ngname from nodegroups' The first column is the nodegroup ID 2. Add the script into the scripts table i.e. # sqlrunner -q 'insert into packages set ngid={Your ngid}, packagename="{Name of the package}"' This bypasses the checking the ngedit tool does, so it allows you to make mistakes.

Hi Mahmoud, 1) Add host allows you to add multiple nodes (pre-populate). To do this use: addhost -f [filename of mac addresses] -j [interface the compute nodes use to provision from] -n [nodegroup name] The mac address file format is the following: aa:bb:cc:dd:ee:ff bb:cc:dd:ee:ff:aa ... 2) When you mean extend what specifically, packages or scripts? If you have 3rd party packages drop them in /depot/contrib/[distribution]/[version]/x86_64 then run the ngedit command to select the custom package(s) you want to install. 3) Using the ngedit command you copy a node group and modify the node group to your liking.
