Hi Ilya, thanks for your answer - really helpful! We were so desparate today due to this bug that we downgraded to -23. But it's very good to know that -31 doesnt contain this bug and we could safely update back to this release. If a new version (say -33 is released): How/Where can I find out if

[ceph-users] Ubuntu Disco with most recent Kernel 5.0.0-32 seems to be instable

Hi all, it seems Ceph on Ubuntu Disco (19.04) with the most recent kernel 5.0.0-32 is instable. It crashes sometimes after a few hours, sometimes even after a few minutes. I found this bug here on CoreOS: https://github.com/coreos/bugs/issues/2616 Which is exactly also the error message I get

[ceph-users] Re: Occasionally ceph.dir.rctime is incorrect (14.2.4 nautilus)

Hi again I've managed to simplify this. I think it only affects empty directories. It is still non-deterministic, ceph.dir.rctime will be set correctly between 30% and 80% of the time, the rest of the time it will be the same as the directory's original mtime. #!/bin/bash

Thanks for responding. It isn’t a session issue, because the port is closed. It wouldn’t bother me if I had to log in again. Thanks, Matthew Stroud On Oct 21, 2019, at 3:25 AM, Volker Theile wrote:  Hi Matthew, that's normal because the session is not authenticated on the failover

[ceph-users] rgw index large omap

I have an rgw index pool that is alerting as "large" in 2 of the 3 osds on the PG. The primary has a large omap. The index is definitely in use by the bucket. Any opinions on the best way to solve this? 1. Remove the 2 osds with large index from cluster and rebalance? 2. Delete 2 of the 3 and
