clusterctl slurm node drain

Take nodes out of production

Synopsis

Set the nodes to drain so that no new job is scheduled on them. Jobs already running are left alone.

The reason is mandatory and comes first, because a drained node with no reason is a node nobody dares resume. Say what is wrong and where it is tracked, on one line of at most 200 characters and without |. A reason that names nodes is refused, since that is what a forgotten reason looks like, and so are nodes named both after the reason and with -n.

The nodes are checked against Slurm before anything is shown: slurmctld reads ALL as every node and a NodeSet name of slurm.conf as its members, so a name Slurm does not read as exactly the node named is refused.

Options inherited from parent commands

      --config strings        configuration file or directory to read, repeatable (default: CLUSTERCTL_CONFIG or the search path)
      --context string        context to act on (default: the current one)
      --dry-run               report what would be done and change nothing
      --fanout int            how many hosts to work on at once, at least 1; caps the service processors and the names asked at once too, which fanout.max and CLUSTERCTL_FANOUT do not (default: from the configuration)
      --force                 allow protected hosts, and nodes the inventory does not know, to be touched
  -n, --nodes stringArray     node set to act on, for example 'exe[1-10],@rack:R02' (default: CLUSTERCTL_NODES)
  -o, --output string         output format: table, wide, json, yaml, nodeset, name, jq= (default "table")
      --progress string       how to show the progress of a command on standard error: auto, tty, counter, plain, none (default: CLUSTERCTL_PROGRESS, else auto, a live tree when standard error is a terminal; plain writes lines for a log)
      --progress-log string   append the progress events of a command to this file, one JSON object per line, created readable by you alone (default: CLUSTERCTL_PROGRESS_LOG; an empty one writes none)
      --set stringArray       override one configuration value as PATH=VALUE, repeatable
  -y, --yes                   answer the confirmation prompts with yes
