Summary: "/bin/bash: bad interpreter: Text file busy":
VanillaSoftwareProcess fails to execute commands
Key: BROOKLYN-294
URL: https://issues.apache.org/jira/browse/BROOKLYN-294
Project: Brooklyn
Issue Type: Improvement
Affects Versions: 0.9.0
Reporter: Aled Sage
When deploying an app to an OpenStack environment (behind a VPN), one of the
VanillaSoftwareProcess entities failed to execute "customize" with the error
shown below:
{noformat}
-bash: /tmp/brooklyn-20160608-111535279-hYmg-customizing_VanillaSoftwarePro.sh:
/bin/bash: bad interpreter: Text file busy
{noformat}
This error means that another process is accessing the file (i.e. has some kind
of lock on it), so we can't execute it.
Just before this, the first attempt to upload the script failed after approx
one minute timeout. I'm guessing that the VPN went down temporarily while it
was trying to upload the script.
I'd have expected that the failed upload would not have kept a lock on the
file, but that seems to be the most likely cause based on the log snippets
below:
