I did have some similar issues and resolved it by installing parted 3.2 (I

Could we infer from this if the usage model is large object sizes rather than
small I/Os the benefit of offloading WAL/DB is questionable given that the
failure of the SSD (assuming shared amongst HDDs) could take down a number of
OSDs and in this case a best practice would be to collocate?
--
I would also add that the journal activity is write intensive so a small part
of the drive would get excessive writes if the journal and data are co-located
on an SSD. This would also be the case where an SSD has multiple journals
associated with many HDDs.

Can you check the value of kernel.pid_max. This may have to be increased for

I would strongly consider your journaling setup, (you do mention that you will
