Question about the file /tmp/blobfuse2.pid

[yangchengs]

A cx reported one issue that one file /tmp/blobfuse2.pid(xxxxx) took 10GB size and it caused the /tmp folder out of space.

In mount.go,

	log.Info("mount: Mounting blobfuse2 on %s", options.MountPath)
	if !options.Foreground {
		pidFile := strings.Replace(options.MountPath, "/", "_", -1) + ".pid"
		pidFileName := filepath.Join(os.ExpandEnv(common.DefaultWorkDir), pidFile)

		pid := os.Getpid()
		fname := fmt.Sprintf("/tmp/blobfuse2.%v", pid)

		dmnCtx := &daemon.Context{
			PidFileName: pidFileName,
			PidFilePerm: 0644,
			Umask:       022,
			LogFileName: fname, // this will redirect stderr of child to given file
		}

Can anyone explain how can I generate a /tmp/blobfuse2.pid with an error?

The /tmp/blobfuse2.pid file gets deleted as soon as the mount is successful,
Could you please share the debug logs.
you can enable the logging by pasting the following at the top of your blobfuse2 configuration file.

logging:
  type: base
  level: log_debug
  file-path: ~/path/to/log/file

Questions:

1. is the mount got successful when this happened?

Closing this issue as removing the fuse-trace option from the config would not increase the file size.
