Hello list, We have made a mistake and dynamically resharded a bucket in a multi-site RGW setup running Quincy (support for this has been added in Reef). So we have now ~200 million objects still stored in the rados cluster, but completely removed from the bucket index (basically ceph has created a new index for the bucket). We would really like to recover these objects, but we are facing a few issues with our ideas. Any help would be appreciated. The main problem we face is that the rados objects contain binary data, where we expected json data. The RGW is configured to use zlib compression, so we think it can be the reason (although using zlib to decompress doesn't work). Has anyone already faced this, and managed to recover the data from rados objects? Another idea we have is to update the new bucket index to inject the old data. This looks possible as the object marker hasn't changed. We also have access to the old indexes/shards, so we could get all the omap key/value pairs and inject them in the new index. Has anyone been mad enough to try this by any chance? Any other idea to recover the data would help of course. Thank you!
