[LU-10701] HSM remove requests are silently ignored when file is being archived

• Type: Bug
• Resolution: Unresolved
• Priority: Minor
• Labels: hsm
• Severity: 3

Description

While a file is being archived, HSM remove requests are silently being dropped. This is because hsm_find_compatible() only looks at the FIDs of actions when scanning for compatible actions.
