ISNSDD(8)

πŸ’– NAME πŸ’–

okay so bestie, meet isnsdd β€” the iSNS discovery daemon. that's it, that's the name, and it's lowkey iconic.


✨ SYNOPSIS ✨

isnsdd [-f] [-c filename] [-d debug-facility]

πŸ¦‹ DESCRIPTION πŸ¦‹

isnsdd is a client-side daemon for iSNS. no cap, its whole job is registering storage nodes and portals with the iSNS service, and then refreshing those registrations on time, every time. punctual queen behavior fr fr. πŸ’…

it also registers itself to receive SCN notifications and processes them as they come in. and get this β€” you can configure it to invoke an external helper application for each status notification it receives. the path name of that helper app gets specified via the SCNCallout option in the configuration file. the way that's customizable?? obsessed. πŸŽ€


πŸ’… OPTIONS πŸ’…

by default, isnsd takes most of its settings from the configuration file /etc/isns/isnsdd.conf, plus whatever you hand it on the command line. here's what you can pass:

  • --config filename, -c filename β€” overrides the default configuration file. bye default, hello yours. ✨
  • --foreground, -f β€” by default, isnsd puts itself into the background (main character needs her privacy). pass this and it runs in the foreground instead. any error messages or debug output get printed to the console rather than being sent to syslog. very "talk to me directly" energy. πŸ’¬
  • --role role β€” this tells the discovery daemon in which capacity it should register itself with the iSNS server. role can be either initiator or control. the default is to register as an initiator.
🫢 heads up bestie: registering target nodes needs a different mechanism, because the iSCSI target server has to inform the discovery daemon about each exported target separately. and that? not implemented yet. we're waiting. πŸ™ˆ
  • --debug facility, -d facility β€” enables debugging. valid facilities are:
    • socket β€” network send/receive
    • auth β€” authentication and security related information
    • message β€” iSNS protocol layer
    • state β€” database state
    • scn β€” SCN (state change notification) messages
    • esi β€” ESI (entity status inquiry) messages
    • all β€” all of the above
