I recreated the placement target and was able to remove the bucket, so thats fixed. Since the bucket is removed, I have deleted the placement target. When I restart RGW, I am getting the following during startup: debug 2024-08-27T13:34:55.850+0000 7f25d9b0f280 0 WARNING: This zone does not contain the placement target temporary present in zonegroup What could cause this? The warning message is correct, the placement target temporary is indeed not present since I removed it, but why does it log/show the message? On 2024-08-26 23:51, Joachim Kraftmayer wrote:
Hi, in older versions of ceph you could download the metadata object, modify it and upload it again. e.g. changing the location constraint. But this is not possible in newer versions of ceph. So the only option I know is to recreate the placement target. Joachim

I created a new placement target/pool. I don't have the exact commands anymore, but something similar to: --- $ radosgw-admin zonegroup placement add \ --rgw-zonegroup default \ --placement-id temporary
$ radosgw-admin zone placement add \ --rgw-zone default \ --placement-id temporary \ --data-pool default.rgw.temporary.data \ --index-pool default.rgw.temporary.index \ --data-extra-pool default.rgw.temporary.non-ec ---
I created a new bucket to use the "default.rgw.temporary.data" as its data pool.
Without removing the bucket, I removed the placement target/rule.
I realised that I still had a bucket, so tried to remove the bucket: --- $ radosgw-admin bucket rm --bucket=tempbucket 2024-08-26T14:12:08.722+0200 7f6c88a73fc0 0 could not find placement rule temporary within zonegroup

So I tried to remove the bucket in a different way: --- $ radosgw-admin metadata rm bucket:tempbucket $ radosgw-admin bucket rm --bucket=tempbucket --- This looked good.
I thought the bucket was removed, but my rgw containers are crashing
when trying to trim (so it seems the bucket is not really removed): --- debug -2> 2024-08-26T12:33:21.291+0000 7eff1bc70700 0 could not

I can recreate (if required for the fix) the metadata info, since I have the output of "radosgw-admin metadata get bucket:tempbucket > tempbucket_metadata.json" by using: --- $ radosgw-admin metadata put bucket:tempbucket < tempbucket_metadata.json ---
What is the best way to recover from this? Recreate the placement rule? Or are there other options? I just want to get rid of the bucket, so my rgw containers don't crash while trying to trim this bucket.
