[LU-11906] "ambiguous redirect" from yml.sh when running in multinode setup

• Type: Bug
• Resolution: Unresolved
• Priority: Major
• Affects Version/s: Lustre 2.12.0, Lustre 2.13.0
• Severity: 3
• Assignee: WC Triage

Description

when trying to run any Lustre tests with bash as the shell (or via auster) and ost_HOST and/or mds_HOST set to a different node, the scripts fail in yaml.sh line 11:

/home/green/git/lustre-release/lustre/tests/yaml.sh: line 11: $logdir/node.$host.yml: ambiguous redirect

The line in question is

        echo "$line" | sed "s/^${host}: //" | sed "s/^${host}://" \
            >> $logdir/node.$host.yml;

if I put quotes around that "$logdir/node.$host.yml" - the error goes away and everything works as intended.

I guess this is the proper way to fix it?

Also this error does not show up if I use "sh" instead of "bash" to run the scripts, but I must use bash as otherwise flakey logic does not work.
