noderun(8) -- Run arbitrary commands per node in a noderange
|
|
=============================================================
|
|
|
|
## SYNOPSIS
|
|
|
|
`noderun <noderange> <command string>`
|
|
|
|
## DESCRIPTION
|
|
|
|
`noderun` will take a given command and execute it in parallel once per node
|
|
in the specified noderange. Attribute expressions as documented in
|
|
nodeattribexpressions(5) are expanded prior to execution of the command. For
|
|
noderun, the commands are locally executed. To execute commands on the nodes
|
|
themselves, see nodeshell(8).
|
|
|
|
## EXAMPLES
|
|
|
|
* Run ping against nodes n1 through n4:
|
|
`# noderun n1-n4 ping -c 1 {nodename}`
|
|
`n3: PING n3 (172.30.2.3) 56(84) bytes of data.`
|
|
`n3: 64 bytes from n3 (172.30.2.3): icmp_seq=1 ttl=64 time=0.387 ms`
|
|
`n3: `
|
|
`n3: --- n3 ping statistics ---`
|
|
`n3: 1 packets transmitted, 1 received, 0% packet loss, time 0ms`
|
|
`n3: rtt min/avg/max/mdev = 0.387/0.387/0.387/0.000 ms`
|
|
`n4: PING n4 (172.30.2.4) 56(84) bytes of data.`
|
|
`n4: 64 bytes from n4 (172.30.2.4): icmp_seq=1 ttl=64 time=0.325 ms`
|
|
`n4: `
|
|
`n4: --- n4 ping statistics ---`
|
|
`n4: 1 packets transmitted, 1 received, 0% packet loss, time 0ms`
|
|
`n4: rtt min/avg/max/mdev = 0.325/0.325/0.325/0.000 ms`
|
|
`n2: PING n2 (172.30.2.2) 56(84) bytes of data.`
|
|
`n2: From odin (172.30.0.6) icmp_seq=1 Destination Host Unreachable`
|
|
`n2: `
|
|
`n2: --- n2 ping statistics ---`
|
|
`n2: 1 packets transmitted, 0 received, +1 errors, 100% packet loss, time 3000ms`
|
|
`n2: `
|
|
`n1: PING n1 (172.30.2.1) 56(84) bytes of data.`
|
|
`n1: `
|
|
`n1: --- n1 ping statistics ---`
|
|
`n1: 1 packets transmitted, 0 received, 100% packet loss, time 10000ms`
|
|
`n1: `
|
|
|
|
* Run an ipmitool raw command against the management controllers of n1 through n4:
|
|
`# noderun n1-n4 ipmitool -I lanplus -U USERID -E -H {hardwaremanagement.manager} raw 0 1`
|
|
`n3: 01 10 00`
|
|
`n1: 01 10 00`
|
|
`n4: 01 10 00`
|
|
`n2: 01 10 00`
|
|
|
|
|
|
* If wanting to use literal {} in the command, they must be escaped by doubling:
|
|
`# noderun n1-n4 "echo {node} | awk '{{print $1}}'"`
|
