PostgreSQL "data" directory disappears simultaneously in 3-node cluster with Pgpool-II

[velasquezjr2022]

Hello Pgpool-II community,
I have a PostgreSQL cluster with 3 nodes (xxxxxl01, xxxxxl02, xxxxxl03) and Pgpool-II. The PostgreSQL data directory is located on a remote instance per company policy.
On the 29th of this month, an incident occurred where the "data" directory disappeared on all 3 nodes simultaneously without apparent cause. It's the third time it's happened. We suspect it may have been caused by a problem on the remote instance hosting the data directories.
Is it possible that a failure on the remote instance could cause the PostgreSQL data directories on all 3 nodes to disappear or be deleted at the same time?
Any suggestions on how to prevent these types of incidents or Pgpool-II and PostgreSQL configuration best practices to avoid data loss in scenarios like this?
I appreciate in advance any guidance or advice you can provide. Greetings.
