[PG_UPGRADE] 9.6 to 10.5

Hi,

I tried to upgrade my PGSQL cluster from 9.6 to 10.5 version through pg_upgrade tool.
I followed the actions noticed in the documentation (https://www.postgresql.org/docs/10/static/pgupgrade.html) and those noticed in the man page of pg_upgrade.

My both clusters (source and target) have been closed with pg_ctl -D /DATA/CLS/clsdata stop commands.
When I try to upgrade my cluster with the following command :

pg_upgrade --old-datadir "/DATA/PPEM/clsdata" --new-datadir "/DATA/PPEM73/clsdata" --old-bindir "/u01/app/postgres/product/9.6.3.0/DERIV01/bin" --new-bindir "/u01/app/postgres/product/10.5.0.0/DERIV01/bin"

Postgres raise the following error :

Performing Consistency Checks
-----------------------------
Checking cluster versions ok

The source cluster was not shut down cleanly.
Failure, exiting

I tried to restart and shutdown clusters with another methods (-m options of pg_ctl, killing processes, ...) still have the same issue.

Best regards,
