initContainer of ws-daemon logs infos as errors

[meysholdt]

In the bash script that creates the raid0, the set -x causes all statements to be printed to stderr when executed, which then get severity "error" in our log system.

Expectation: info-messages should not be errors. Maybe -v instead of -x does the trick. Or something with BASH_XTRACEFD.

I'm filing this issue because the errors led to confusion here
