Error Message:
unable to open bigfile bigfile000 exclusive
Context: This error typically appears in backup software logs (most commonly Commvault) during a backup, restore, or auxiliary copy operation. It signifies that the process cannot access a chunk of backup data (referred to as a "bigfile") because it cannot secure exclusive rights to it. ls -la bigfile000
Technical Translation:
The application is trying to open a file (usually a chunk of backup data stored on disk or tape) with O_EXCL (exclusive) flags or requesting a lock that prevents other processes from reading or writing to it simultaneously. The Operating System returned an error (likely EACCES or EPERM) preventing this action.
| Cause | Description |
|-------|-------------|
| File already opened exclusively | Another process or thread holds an exclusive lock on the same file. |
| Insufficient filesystem permissions | The process lacks write access to the file or its directory. |
| File doesn’t exist and creation failed | If the process expects the file to be present or to create it, lack of write permission or space can cause this. |
| Filesystem limitations | Some filesystems don’t support large files or exclusive locking properly (e.g., NFS with nolock option). |
| Stale lock or orphaned process | A previous process crashed, leaving an exclusive lock behind (especially on Windows or with mandatory locking). |
| Anti-virus or backup software | Real-time scanning tools may temporarily hold a handle to the file, blocking exclusive access. | Ensure the process user (e
Program Files folders have strict permissions. Moving the game to a user-created folder or a different drive eliminates many file-locking issues.
This is the most frequent culprit. Another program (anti-virus, a cloud backup service, or even a previous instance of the game that didn't shut down properly) has already locked the file.
