What has DWPD to do with performance / IOPS? The SSD will just fail earlier,
but it should not have any affect on the performance, right?
Correct me if I am wrong, just want to learn.

Hi Nick,
Interesting your note on PG locking, but I would be surprised if its
effect is that bad. I would think that in your example the 2 ms is a
total latency, the lock will probably be applied to small portion of
that, so the concurrent operations are not serialized for the entire
time..but ag

Hi,
According to the source code of ceph11.2.0，we known that Bluestore WAL and
DB are s stored in the top 4% of the OSD disk space.But I found that it didn't
really need so much.I decided to modify it to 0.5%, then the meta data size was
usually just less than 0.2% in the experiment.Due to
I did not only "osd bench". Performed rbd image mapped and DD test on
it... here also got very less number with image on SSD pool as
compared with image on HDD pool.
As per SSD datasheet - they claim 500 MB/s, but I am getting somewhat
near 50 MB/s with dd cmd.

Hi!
Apparently the message had nothing to do with the issue. It was just that after
the threads affected by the SIGHUP issue crashed, the keystone-related stuff
was all that’s left.
