different clush.conf options for different hosts

[brianjmurrell]

How can I have different options for different groups of nodes a la clush.conf style?

For example for hosts foo-[1-5], I want to set ssh_options to one set of options but for foo-[6-9], I want ssh_options to be a different set of options.

Is this possible in any way? clush.conf appears to be a global set of options for all nodes.

This is not possible inside clustershell but the best way to do this for you is probably to put them in ssh_config file.

If you don't want to change your global config, you can specify that in a dedicated ssh_config and specify it to be used by clustershell, either on the command line with "-o -F <FILE>" or in clush.conf with the same options.

I suppose ssh_options was a bad example.

What if I want a different ssh_path for different groups of hosts?

[degremont]

Indeed this is not possible with the command line tools. You can only do that with the python API.

But it's using the clush to replace pdsh that is my use-case. :-(

Can we make this an RFE then?

[degremont]

This is possible with pdsh? Could you point me to a doc explaining how pdsh is doing that?

[brianjmurrell]

I wasn't saying it was possible with pdsh. I was looking to clush as a replacement, to be better than pdsh but unfortunately this is one area where it isn't.

[degremont]

We could consider this as an RFE, but I assume this is not a blocker for your replacement, as pdsh does not have this feature either. And CS has already a lot of very interesting additional features compared to pdsh ;)

[brianjmurrell]

No, not a blocker and agreed, that CS does already have lots of interesting features over pdsh.
