Hi 皓月,
You can try "ls -al /mnt/ceph ", check if the current user have W/R access to
the directory. Maybe you need to use "chown" to change the directory owner.

Looks very good. Is it anyhow possible to display the reason why a
cluster is in an error or warning state? Thinking about the output from
ceph -s if this could by shown in case there's a failure. I think this
will not be provided by default but wondering if it's possible to add.

Hi Oliver,
a good value is 100-150 PGs per OSD. So in your case between 20k and 30k.
You can increase your PGs, but keep in mind that this will keep the
cluster quite busy for some while. That said I would rather increase in
smaller steps than in one large move.

I'm also not 100% sure but I think that the first one is the right way
to go. The second command only specifies the db partition but no
dedicated WAL partition. The first one should do the trick.
