Description shilpa 2024-09-10 19:04:33 UTC

Description of problem:
based on upstream ceph tracker
https://tracker.ceph.com/issues/63378

Version-Release number of selected component (if applicable):


How reproducible:
reproduces in teuthology. not easily reproducible by hand.

Steps to Reproduce:
test data sync init after bucket sync disable/enable in combination with resharding.
1. create multiple buckets
2. add some objects
3. reshard the buckets
4. bucket sync disable, add more objects and enable bucket sync
5. wait for bucket sync to catch up
5. stop secondary gateway and add more objects and buckets on primary
6. run data sync init on secondary
7. restart secondary gateway
(actual tests are in upstream multisite suite. need to enable all bucket sync and data sync init tests)

Actual results:
crash with the segfault:
