bucket reshard fails with ERROR: bi_list(): (4) Interrupted system call

[Andreas Calminder <andreas.calminder@xxxxxxxxxx>]

Hi,

I'm running Jewel (10.2.7). While trying to get rid of an oversized bucket (+14M objects) I tried to reshard the bucket index be able to remove it.

As per the Red Hat documentation I ran
# radosgw-admin bucket reshard --bucket=oversized_bucket --num-shards=300

I noted the old instance id and waited for it to output a count of all items, at the very end it spits out "ERROR: bi_list(): (4) Interrupted system call"

Now I have the new bucket instance with 300 shards, seemingly unused and the old instance id which seems to be active

#  radosgw-admin --cluster drceph-tcs-prod metadata get bucket:oversized_bucket returns the old instance id in bucket_id

Two questions:

* How do I remove the new bucket id, from the failed reshard command. Since it's not used it's confusing to have it floating around

* How do I actually reshard the oversized_bucket? - Actually, I really don't care about the bucket, If there's a way to remove the bucket and it's objects without altering the index, causing the radosgw to allocate all memory available and crash, I'd rather do that.

Regards,

Andreas
