Opened: Dec 05, 2024

Severity: 3-Major

Symptoms

1) On GUI, "Fixed Ratio" value under "System >> Crypto Offloading : Acceleration Strategy" is shown as empty. 2) After seeing/setting empty "Fixed Ratio" value on GUI, while trying to re-add any value at "Fixed Ratio" parameter on GUI, GUI returns an error "An error has occurred while trying to process your request." and unable to set a value. "/var/log/webui.log" recorded error message. ERROR [ajp-bio-127.0.0.1-8009-exec-8] acceleration_strategy.AccelerationStrategyHandler:trigger - General error: 01020066:3: The requested Crypto Global Settings () already exists in partition Common. in statement [INSERT into crypto_globals (name,fixed_ratio) VALUES (?,?)] Although the GUI returns an error, looking at the current value by "tmsh list /sys crypto acceleration-strategy fixed-ratio", the last set value is still displayed.

Impact

Unable to set any value at "Fixed Ratio" box on GUI.

Conditions

Any one of these two are known to trigger this problem. -- On GUI, press "Update" button while no "Fixed Ratio" parameter is set (empty). Then, reboot. -- On GUI or TMSH, try setting wrong value (e.g., "999999" or "-1", both of these 2 values are out of range and not accepted by mcpd) at "Fixed Ratio" parameter. Then, reboot.

Workaround

Update "Fixed Ratio" parameter via TMSH. Once the proper value is set via TMSH, the GUI resumes working and it is possible to modify the "Fixed Ratio" parameter via the GUI. # tmsh modify /sys crypto acceleration-strategy fixed-ratio 1000 ; tmsh save /sys config
