Hello,
I've just upgraded a Pacific cluster into Quincy, and all my osd have
the low value osd_mclock_max_capacity_iops_hdd : 315.00.
The manuel does not explain how to benchmark the OSD with fio or ceph
bench with good options.
Can someone have the good ceph bench options or fio options
If the crash is easily reproducible at your end, could you set debug_client
to 20 in the client-side conf file and then reattempt the operation.
You could then send over the collected logs and we could take a look at
them.
FYI - there's also a bug tracker that has identified a similar problem:

I created a tracker issue, maybe that will get some attention:

Hi Eugen,
Thank you very much for these detailed tests that match what I
observed and reported earlier. I'm happy to see that we have the

Hi Rafael.
We faced the exact same issue. And we did a bunch of tests and question.
We started with some FIOs, but results where quite meh once in production. Ceph
bench did not seemed very reliable.
What we ended up doing and seems to hold up quite nicely, is the above. It's
probably not the
Hello,
we have a Ceph 17.2.5 cluster with a total of 26 nodes, where 15 nodes that
have faulty NVMe drives,
where the db/wal resides (one NVMe for the first 6 OSDs and another for the
remaining 6).
We replaced them with new drives and pvmoved it to avoid losing the OSDs.
So far, there are n
Hi Luis,
Thank you for sharing your tricks :)
OK it's clever.
You by-pass a destroying disk fio bench with a test on a unique PG on a
single OSD, and then do some rados bench.
In this way you should get a more realistic ceph IOPS !

Hi
you're correct that the distinction is between metadata and data;
metadata like users and buckets will replicate to all zonegroups,
while object data only replicates within a single zonegroup. any given
bucket is 'owned' by the zonegroup that creates it (or overridden by
the LocationConstraint on c

Actually, I reported a documentation bug for something very similar.

Hi everyone,
This is the second release candidate for Reef.
The Reef release comes with a new RockDB version (7.9.2) [0], which
incorporates several performance improvements and features. Our
internal testing doesn't show any side effects from the new version,
but we are very eager to hear commun
