Would you run this mount repair command?

Situation

Codex generated a quick repair command after a storage alert on a PostgreSQL host.

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.

bash -c "set -euo pipefail
MOUNT=/var/lib/postgresql
DEV=$(python3 -c 'import os, subprocess; src=subprocess.check_output(["findmnt","-n","-o","SOURCE","/var/lib/postgresql"], text=True).strip(); print(os.path.realpath(src))')
sudo umount -l "$MOUNT" || true
sudo wipefs -a "$DEV" && sudo mkfs.ext4 -F "$DEV"
sudo mount "$DEV" "$MOUNT""
