linux - fuse 错误 : Transport endpoint is not connected

Question

我正在尝试实现 FUSE 文件系统。我收到此错误:

cannot access MountDir: Transport endpoint is not connected

这是程序的相关部分。有两个目录，MirrorDir 和 MountDir，它们与所有代码位于同一目录中。我这样调用程序:

./myFS -o nonempty -o allow_other MirrorDir MountDir

谁能看出我做错了什么？

static struct fuse_operations xmp_oper = {
    .getattr    = xmp_getattr,
    .readdir    = xmp_readdir,
    .open       = xmp_open,
    .read       = xmp_read,
};

int main(int argc, char *argv[]) {
    int fuse_stat;
    char* mirrorDir;

    mirrorDir = malloc(sizeof(strlen(argv[argc-2]+1)));
    if (mirrorDir == NULL) {
        perror("main calloc");
        abort();
    }

    // Pull the rootdir out of the argument list and save it in my internal data
    mirrorDir = realpath(argv[argc-2], NULL);

    argv[argc-2] = argv[argc-1];
    argv[argc-1] = NULL;
    argc--;

    // turn over control to fuse
    fprintf(stderr, "about to call fuse_main\n");   
    fuse_stat = fuse_main(argc, argv, &xmp_oper, mirrorDir);
    fprintf(stderr, "fuse_main returned %d\n", fuse_stat);
    return fuse_stat;
}

这通常是由于文件系统崩溃而导致挂载目录挂载。进入挂载点的父目录，输入fusermount -u YOUR_MNT_DIR。

如果这不起作用，请执行 sudo umount -l YOUR_MNT_DIR。
