I see there's a very specific test-case here in the bug to verify if the issue is resolved, but I don't see any mention of it being ran as part of verification.

[Bug 1843085] Re: Backport of zero-length gc chain fixes to Luminous
** Description changed:
[Impact]
Cancelling large S3/Swift object puts may result in garbage collection
entries with zero-length chains. Rados gateway garbage collection does not
efficiently process and clean up these zero-length chains.
A large number of zero-length chains will result in rgw processes
quickly spinning through the garbage collection lists doing very little
work. This can result in abnormally high cpu utilization and op
workloads.
[Test Case]
Modify garbage collection parameters by editing ceph.conf on the target rgw:
```
- [client.rgw.juju-29f238-sf00242079-4]
rgw enable gc threads = false
rgw gc obj min wait = 60
rgw gc processor period = 60
```
Restart the ceph-radosgw service to apply the new configuration:
- `sudo systemctl restart ceph-rado...@rgw.juju-29f238-sf00242079-4`
+ `sudo systemctl restart ceph-radosgw@rgw.$HOSTNAME`
Repeatedly interrupt 512MB object put requests for randomized object names:
```
for i in {0..1000}; do
f=$(mktemp); fallocate -l 512M $f
- s3cmd put $f s3://test_bucket.juju-29f238-sf00242079-4 --disable-multipart &
+ s3cmd put $f s3://test_bucket --disable-multipart &
pid=$!
sleep $((RANDOM % 7 + 3)); kill $pid
rm $f
done
```
Delete all objects in the bucket index:
```
- for f in $(s3cmd ls s3://test_bucket.juju-29f238-sf00242079-4 | awk '{print
$4}'); do
+ for f in $(s3cmd ls s3://test_bucket | awk '{print $4}'); do
s3cmd del $f
done
```
By default rgw_max_gc_objs splits the garbage collection list into 32 shards.
Capture omap detail and verify zero-length chains were left over:
```
+ export CEPH_ARGS="--id=rgw.$HOSTNAME"
for i in {0..31}; do
- sudo rados -p default.rgw.log --namespace gc listomapvals gc.$i
+ sudo -E rados -p default.rgw.log --namespace gc listomapvals gc.$i
done
```
Confirm the garbage collection list contains expired objects by listing
expiration timestamps:
- `sudo radosgw-admin gc list | grep time; date`
+ `sudo -E radosgw-admin gc list | grep time; date`
Raise the debug level and process the garbage collection list:
- `CEPH_ARGS="--debug-rgw=20 --err-to-stderr" sudo -E radosgw-admin gc process`
+ `sudo -E radosgw-admin --debug-rgw=20 --err-to-stderr gc process`
Use the logs to verify the garbage collection process iterates through all
remaining omap entry tags. Then confirm all rados objects have been cleaned up:
- `sudo rados -p default.rgw.buckets.data ls`
-
+ `sudo -E rados -p default.rgw.buckets.data ls`
[Regression Potential]
Backport has been accepted into the Luminous release stable branch upstream.
[Other Information]
This issue has been reported upstream [0] and was fixed in Nautilus alongside
a number of other garbage collection issues/enhancements in pr#26601 [1]:
* adds additional logging to make future debugging easier.
* resolves bug where the truncated flag was not always set correctly in
gc_iterate_entries
* resolves bug where marker in RGWGC::process was not advanced
* resolves bug in which gc entries with a zero-length chain were not trimmed
* resolves bug where same gc entry tag was added to list for deletion
multiple times
These fixes were slated for back-port into Luminous and Mimic, but the
Luminous work was not completed because of a required dependency: AIO GC
[2]. This dependency has been resolved upstream, and is pending SRU
verification in Ubuntu packages [3].

Hello Kellen, or anyone else affected, Accepted ceph into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/ceph/12.2.12-0ubuntu0.18.04.4 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B.
