Hi,

Initially my playbook stuck at setup stage for a specific server.

Upon running ansible -vvvv -m setup , the process also stuck.

I have set the environment variable ANSIBLE\_KEEP\_REMOTE\_FILES=1 then trying again, and still stuck.

In the target server, I went to the folder /root/.ansible/tmp/ansible-tmp-1472920749.88-102164203403323 and executed

python -m trace --trace ./setup

it stuck at the last line:

— modulename: subprocess, funcname: close\_unregister\_and\_remove  
subprocess.py(1437): poller.unregister(fd)  
subprocess.py(1438): fd2file[fd].close()

subprocess.py(1453): while fd2file:  
subprocess.py(1454): try:  
subprocess.py(1455): ready = poller.poll()

when pressing ctrl-c, the traceback is:

KeyboardInterrupt

For other machine, they did not stuck at the polling process.

Any idea to troubleshoot further?

Thanks

It might be that the node has some file system issues, setup is gathering information about mount points and can be hanging there.

Do running "mount" and/or "df" manually on the node return successfully?

this issue was solved by my colleague

it turns out that there is LVM lock that cause vgs command to stall

clearing that lock, also allow vgs to complete, and ansible to work after that

in summary, if you are stuck with setup, check your filesystem.
