Thanks!
Playing around with max_keys in bucket listing retrieval actually
gives me results or not, this gives me a way to list the content
until the bug is fixed.
Is it possible somehow to copy the objects to a new bucket (with
versioning disabled), and rename the current one? I don't think
the latter is possible through the api but maybe there is some
hidden way ;-)
Could you also take a minute to confirm another versioning related
bug I posted: http://tracker.ceph.com/issues/12819
If you could give me some pointers to contribute, I don't mind
digging into code, I will gladly do so.

Yeah, I'm able to reproduce the issue. It is related to the fact that
you have a bunch of delete markers in the bucket, as it triggers some
bug there. I opened a new ceph issue for this one:

Sorry, forgot to mention:
- yes, filtered by thread
- the "is not valid" line occurred when performing the bucket --check
- when doing a bucket listing, I also get an "is not valid", but on a
different object:
7fe4f1d5b700 20 <cls> cls/rgw/cls_rgw.cc:460: entry
abc_econtract/data/6scbrrlo4vttk72melewizj6n3[] is not valid

I assume you filtered the log by thread? I don't see the response
messages. For the bucket check you can run radosgw-admin with
--log-to-stderr.
nothing is logged to the console when I do that
Can you also set 'debug objclass = 20' on the osds? You can do it by:
$ ceph tell osd.\* injectargs --debug-objclass 20
this continuously prints "20 <cls> cls/rgw/cls_rgw.cc:460: entry
abc_econtract/data/6smuz2ysavvxbygng34tgusyse[] is not valid" on osd.0
Also, it'd be interesting to get the following:
$ radosgw-admin bi list --bucket=<bucket name>
--object=abc_econtract/data/6shflrwbwwcm6dsemrpjit2li3v913iad1EZQ3.S6Prb-NXLvfQRlaWC5nBYp5
this gives me an empty array:
[
]
but we did a trim of the bilog a while ago cause a lot entries regarding
objects that were already removed from the bucket kept on syncing with
the sync agent, causing a lot of delete_markers at the replication site.
The object in the error above from the osd log, gives the following:
# radosgw-admin --log-to-stderr -n client.radosgw.be-east-1 bi list
--bucket=aws-cmis-prod
--object=abc_econtract/data/6smuz2ysavvxbygng34tgusyse

Hi, I've started the bucket --check --fix on friday evening and it's
still running. 'ceph -s' shows the cluster health as OK, I don't know if
there is anything else I could check? Is there a way of finding out if
its actually doing something?
We only have this issue on the one bucket with versioning enabled, I
can't get rid of the feeling it has something todo with that. The
"underscore bug" is also still present on that bucket
(http://tracker.ceph.com/issues/12819). Not sure if thats related in any
way.
Are there any alternatives, as for example copy all the objects into a
new bucket without versioning? Simple way would be to list the objects
and copy them to a new bucket, but bucket listing is not working so...

This generally shouldn't be a problem at your bucket sizes. Have you
checked that the cluster is actually in a healthy state? The sleeping
locks are normal but should be getting woken up; if they aren't it
means the object access isn't working for some reason. A down PG or
something would be the simplest explanation.

Hi,
this bucket only has 13389 objects, so the index size shouldn't be a
problem. Also, on the same cluster we have an other bucket with 1200543
objects (but no versioning configured), which has no issues.
when we run a radosgw-admin bucket --check (--fix), nothing seems to be
happening. Putting an strace on the process shows a lot of lines like these:
[pid 99372] futex(0x2d730d4, FUTEX_WAIT_PRIVATE, 156619, NULL
<unfinished ...>
[pid 99385] futex(0x2da9410, FUTEX_WAIT_PRIVATE, 2, NULL <unfinished ...>
[pid 99371] futex(0x2da9410, FUTEX_WAKE_PRIVATE, 1 <unfinished ...>
[pid 99385] <... futex resumed> ) = -1 EAGAIN (Resource
temporarily unavailable)
[pid 99371] <... futex resumed> ) = 0
but no errors in the ceph logs or health warnings.

How many objects in the bucket?
RGW has problems with index size once number of objects gets into the
900000+ level. The buckets need to be recreated with 'sharded bucket
indexes' on:
rgw override bucket index max shards = 23
You could also try repairing the index with:
radosgw-admin bucket check --fix --bucket=<bucketname>

Hi,
we have a rgw bucket (with versioning) where PUT and GET operations for
specific objects succeed, but retrieving an object list fails.
Using python-boto, after a timeout just gives us an 500 internal error;
radosgw-admin just hangs.
Also a radosgw-admin bucket check just seems to hang...
ceph version is 0.94.3 but this also was happening with 0.94.2, we
quietly hoped upgrading would fix but it didn't...
