There are any number of bits of software that call themselves ssm. Assuming
this is system storage manager why don’t you pass -f to make it non-interactive?
commands => :ssm => ‘/usr/bin/ssm’
args=%W[-f create --fs @resource[:fs_type] -p @resource[:volume_group] -n
@resource[:logical_volume] @resource[:mount_point]]
ssm(*args)
If that isn’t an option you could pass a file containing ‘yes’
cmd=%W[ssm create --fs @resource[:fs_type] -p @resource[:volume_group] -n
@resource[:logical_volume] @resource[:mount_point]]
Puppet::Util::Execution.execute(cmd, :stdinfile => ‘/path/to/yes-file’)

You really shouldn’t do that. Your invocation is off. The system call is not
using you definition
of ssm above it’s just finding it on the path and you need to expand your args
system takes a string.
args=%w(this is s a test)
[5] pry(main)> system("yes | echo #{args.join(' ')}")
this is s a test
