Would you run this mount repair command?

Situation

Environment

Production database host. /var/lib/postgresql is the mounted data volume for the primary PostgreSQL instance, and backups exist but restore requires failover.

Select suspicious lines in the terminal to flag them before submitting your verdict.

sudo umount -l "$MOUNT" || true
