====== The error ======
You get:
<code bash>
Error ERANGE: pool id 4 pg_num 500 size 3 would mean 6000 total pgs, which exceeds max 5000 (mon_max_pg_per_osd 250 * num_in_osds 20)
</code>
While modifying PGs-per-pool:

<code bash>
ceph osd pool set ${POOL_NAME} pg_num 500
</code>

====== The solution ======
There is no problem here.\\
You're just exceeding a configured "maximum" of the storage.\\
