調査の方向性

Start by tracing the mount and dismount paths named in the request: GUI, tray, hotkeys, auto-dismount, and command-line /d; the issue does not identify source files or tests. Determine where per-favorite settings are stored and how commands could run with a timeout and affect dismount. Done means commands run at the requested lifecycle points across those paths, with the specified cancellation behavior.

説明

Desired behavior

Follow-up to #131, which was closed automatically by the stale bot in 2021 without being implemented. I need this specifically on Windows 11, where there is currently no reliable way to do it.

Please add the ability to run local commands after mount and before/after dismount, configured per favorite volume.

Use case: we keep a PostgreSQL data directory on a VeraCrypt volume (Windows service). The service must be started after the volume is mounted and, more importantly, stopped before dismount: PostgreSQL's background processes keep files open, so a normal dismount fails with "files in use", and a forced dismount (including auto-dismount on user logoff with "Force auto-dismount" enabled) makes PostgreSQL crash and run crash recovery on the next start.

Why existing Windows 11 mechanisms don't solve it:

  • Wrapper .bat/.ps1 scripts around VeraCrypt.exe /v and /d only work when the user uses them; they don't cover mounting/dismounting from the GUI, tray icon, hotkeys or auto-dismount.
  • Group Policy shutdown scripts run only after user logoff, i.e. after VeraCrypt's logoff auto-dismount has already happened, and they are skipped entirely when Fast Startup is enabled (Windows 11 default).
  • Polling for the drive letter in a scheduled task covers mount only, not dismount.

Screenshots/Mockup/Designs

In Favorites > Organize Favorite Volumes, three new fields per volume:

  • Run after mount: [ command ]
  • Run before dismount: [ command ] timeout: [ 60 ] s
  • Run after dismount: [ command ]

Additional information

  • Run "before dismount" synchronously (with the configurable timeout) before VeraCrypt checks for open files, for every dismount path: GUI, tray, hotkey, auto-dismount (logoff, power saving, inactivity), command line /d.
  • Allow the command to run elevated if needed (stopping a Windows service requires administrator rights).
  • Pass drive letter and volume path as arguments or environment variables.
  • If the pre-dismount command returns non-zero, cancel the dismount (unless forced).
  • Commands are stored locally (not inside the container), which avoids the security concern of a volume executing code on mount.

This would cover any Windows service whose data lives on an encrypted volume (databases, sync clients, backup agents).
