Hi all, We have recently upgraded from Jewel (10.2.10) to Luminous (12.2.5) and after this we decided to update our tunables configuration to the optimals, which were previously at Firefly. During this process, we have noticed the OSDs (bluestore) rapidly filling on the RGW index and GC pool. We estimated the index to consume around 30G of space and the GC negligible, but they are now filling all 4 OSDs per host which contain 2TB SSDs in each.
Does anyone have any experience with this, or how to determine why the sudden growth has been encountered during recovery after the tunables update? We have disabled resharding activity due to this issue, https://tracker.ceph.com/issues/24551 and our gc queue is only a few items at present.
