[LU-15142] LCTL: permanent parameter deletion and llog_print issues

• Status: Resolved
• Project: Lustre
• Fix Version/s: Lustre 2.15.0
• Type: Bug
• Priority: Minor
• Reporter: Mikhail Pershin
• Assignee: Mikhail Pershin
• Resolution: Fixed
• Severity: 3

Description

There are several issues with LCTL to fix:

• llog_print params shows all parameters without filtering deleted (i.e having SKIP flag), so its output is confusing and that could be problematic to parse its output correctly due to that
• it looks like there is parsing bug, so command like that lctl set_param -P -d mdt.lustre-MDT0000.dom_read_open=1 cause setting parameter in form 'mdt.lustre-MDT0000.dom_read_open=111=' instead of deleting dom_read_open fg
• lctl llog_print cause segfault, so it has issue with correct parameters parsing
