Symptoms
När du har skapat en livscykelpolicy (som inte har något prefix) i bucketen returnerar de interna felen 500 för GET- eller PUT- eller DELETE-objektbegäran. List bucket fungerar bra.
Om du kontrollerar befintlig policy för objekt xxx med prefix null visas detta i dataheadsvc.log.

Cause
För AWS har varje regel element som har underordnade element: , , krävs XML-elementet, och är valfritt (gäller för alla objekt i bucketar).
För ECS stöder vi endast filter och har inte -elementet som är utformat för XML-begäran. är inte obligatorisk parameter, men i vissa platskoder används prefixvärdet direkt (null-punkt), vilket orsakar problem här.
Resolution
Om felloggen visas som i fältet "Problem" kontrollerar du om livscykeln är inställd i bucketen och att inget prefix har konfigurerats. Mer information om hur du använder s3curl.pl finns i
manualen för ECS-dataåtkomst .

If you confirm that hit this issue, the workaround prior to 3.2 is to add in lifecycle.
This issue is fixed in 3.2.
Workaround:
1. Get current lifecycle setting and save to local file
# ./s3curl.pl --id=test -- http://:9020//?lifecycle -o lifecycle.xml
# ./s3curl.pl --id=test -- http://:9020//?lifecycle -o lifecycle.xml

Dload Upload Total Spent Left Speed
100 268 100 268 0 0 11926 0 --:--:-- --:--:-- --:--:-- 12181
2. Modify the lifecycle.xml and add prefix
# vi lifecycle.xml
-->add this line
Enabled

3. Update lifecycle
# ./s3curl.pl --id=test --put=lifecycle.xml http://xx.xx.xx.xx:9020//?lifecycle --calculateContentMd5 --debug
# ./s3curl.pl --id=test --put=lifecycle.xml http://xx.xx.xx.xx:9020/fog-bbr-backup/?lifecycle --calculateContentMd5 --debug
