✨ LCTL-NODEMAP_INFO(8) ✨

okay bestie, so this is a page from the Lustre Configuration Utilities manual β€” it's the lctl-nodemap_info one πŸ’–


🌸 NAME 🌸

lctl-nodemap_info β€” the little command that spills the tea about your nodemaps πŸ’…


πŸ¦‹ SYNOPSIS πŸ¦‹

lctl nodemap_info or
lctl nodemap info --name NODEMAP_NAME --property PROPERTY_NAME --list

πŸ’œ DESCRIPTION πŸ’œ

So like, nodemap_info is the one that hands you the receipts on all your defined nodemaps ✨ That means: are your nodemaps even active or nah, a whole list of every nodemap that's defined, and the actual values of specific nodemap parameters.

And here's the cute part β€” if you don't pass any options at all, it just gives you everything: every nodemap and every property it's got πŸ‘‘


πŸŽ€ OPTIONS πŸŽ€

  • --name NODEMAP_NAME β€” tells it which nodemap you wanna hear about, by name. Skip it and you get all of them, no gatekeeping πŸ’– You can pair this with --property to pull the value of one specific property off one specific nodemap.
  • --property PROPERTY_NAME β€” says which property's value you want to see. Don't specify it and, yep, all the properties get shown 🌈 You can run this alongside --name to get that one property for that one nodemap.
  • --list β€” shows the global nodemap state and Lists all defined nodemaps plus the nodemap properties that are available πŸ‘‘
