I run an simple ansible module unarchive in ansible-playbook.
the module look like below:
`
- name: untar the psutil module
sudo: yes
unarchive: src=psutil-2.1.0.tar.gz dest=/tmp/
`
then, the stange thing happen.
it crash at one machine.
`
failed: [hadoop4] => {“failed”: true, “item”: “”}
msg: dest ‘/tmp/’ must be an existing dir
`
absolutely,the dir must exist
After some debug, I found the bug is locate at ansible/runner/connection_plugins/ paramiko_ssh.py
`
def exec_command(self, cmd, tmp_path, sudo_user=None, sudoable=False, executable=‘/bin/sh’, in_data=None, su=None, su_user=None):
…
try:
chan.exec_command(shcmd)
if self.runner.sudo_pass or self.runner.su_pass:
while not sudo_output.endswith(prompt) and success_key not in sudo_output:
chunk = chan.recv(bufsize)
if not chunk:
if ‘unknown user’ in sudo_output:
raise errors.AnsibleError(
‘user %s does not exist’ % sudo_user)
else:
raise errors.AnsibleError('ssh connection ’ +
‘closed waiting for password prompt’)
sudo_output += chunk
print “sudo_op”
print sudo_output
print “end”
if success_key not in sudo_output:
if sudoable:
chan.sendall(self.runner.sudo_pass + ‘\n’)
elif su:
chan.sendall(self.runner.su_pass + ‘\n’)
except socket.timeout:
raise errors.AnsibleError(‘ssh timed out waiting for sudo.\n’ + sudo_output)
stdout = ‘’.join(chan.makefile(‘rb’, bufsize))
stderr = ‘’.join(chan.makefile_stderr(‘rb’, bufsize))
print “stdout”
print stdout
print “stderr”
print stderr
`
after i add some print out code,I get the result look like below:
correct machine:
`
make sudo cmd

`
It look like the the stdout shoule add back the sudo_output??
And I want to know is it possible to reset some config for the worng machine to work right.
