bosh-release 271 Inappropriate ioctl for device (Errno::ENOTTY)

[saketlj]

Hi Team,

We are using bosh-release 271 and logging to bosh console with /var/vcap/jobs/director/bin/console and running some ruby inbuilt bosh code to clean up DB tasks.

count=(Bosh::Director::Models::Task.where(type: 'vms').count-2000)/10

I am getting below error regards to ioctl winsize error.

/var/vcap/data/packages/ruby-3.0.2-r0.67.0/23d7612192d5eb20127684cc602ad13a0778fdc1/lib/ruby/3.0.0/irb/input-method.rb:42:in `winsize': Inappropriate ioctl for device (Errno::ENOTTY)

Inappropriate ioctl for device normally means that some program attempted to do a terminal control operation but its standard I/O streams weren't connected to a terminal.

Did any 1 came across this error ?

Hi @saketlj,

I can't reproduce the error above with the bosh version 271.16.0. Which version do you use exactly?

[saketlj]

@beyhan I am using 271.8.0 bosh release.

Strange thing is when i run this manually ( login to bosh director and the calling /var/vcap/jobs/director/bin/console) I am able to run this successfully, only first attempt was unsuccessful with same error.

I am doing this through automated flow with concourse task, copying bash script to director which runs below code.

#/bin/bash
/var/vcap/jobs/director/bin/console <<EOF
count=(Bosh::Director::Models::Task.where(type: 'vms').count-2000)/10
if count > 0
tr=Bosh::Director::Api::TaskRemover.new(2000)
count.times {tr.remove('vms')}
end
EOF

This seems ruby issue.

@beyhan We are still having this issue and bosh version is 271.20.0

When I run script manually it runs successfully but when I try to redirect o/p of this script to temp file, it prints below ioctl error message after variable assignment operation only.

for e.g :
count = Bosh::Director::Models::Task.where(type: 'vms').count-1000

Maybe IRB bug!

I haven't found any solution in ruby community for this.
