Re: "No space left on device" errors

I hope the nathans fix can probably do the thing, however it does not cover the the log referenced in the description of  https://tracker.ceph.com/issues/42313 because teuthology worker does not include that fix which is supposed to be cause for "No space left on device" issue.

Can some one give one-job teuthology-suite command  that 100% reproducing the issue?

Yuri just reminded me that he's seeing this problem on the mimic branch.

Does that mean this PR just needs to be backported to all branches?

https://github.com/ceph/ceph/pull/30792

I'd be surprised if that one (changing iteritems() to items()) could
cause this, and it's not a fix for any known bugs, just ongoing py3
work.

When I said "that commit" I was referring to
https://github.com/ceph/teuthology/commit/41a13eca480e38cfeeba7a180b4516b90598c39b,
which is in the teuthology repo and thus hits every test run. Looking
at the comments across https://github.com/ceph/teuthology/pull/1332
and https://tracker.ceph.com/issues/42313 it sounds like that
teuthology commit accidentally fixed a bug which triggered another bug
that we're not sure how to resolve, but perhaps I'm misunderstanding?


I think I understand what's going on. Here's an interim fix:
https://github.com/ceph/teuthology/pull/1334

Assuming this PR really does fix the issue, the "real" fix will be to drop
get_wwn_id_map altogether, since it has long outlived its usefulness ( see
https://tracker.ceph.com/issues/14855 ).
