使用mhddfs合并/dev/sda2与/dev/sdb3失败求助：提示fuse设备未找到

Hey there, let's work through this mhddfs issue step by step. First off, that error message has a tiny typo—modpd should be modprobe—but let's cover all bases to get your partitions merged properly.

Step 1: Load the FUSE Kernel Module #

The error is pointing out that the FUSE kernel module (which mhddfs depends on) isn't loaded. Run the corrected command first:

sudo modprobe fuse

To confirm it loaded successfully, check with:

lsmod | grep fuse

You should see a line containing fuse in the output if it worked.

Step 2: Verify (or Create) the FUSE Device Node #

If loading the module doesn't fix things, the /dev/fuse device node might be missing. Let's check:

ls -l /dev/fuse

If this returns "No such file or directory", create the node manually:

sudo mknod /dev/fuse c 10 229
sudo chmod 666 /dev/fuse

The c 10 229 specifies it's a character device with the standard major/minor numbers for FUSE.

Step 3: Double-Check Your mhddfs Command #

Make sure you're using the right syntax and have proper permissions:

1. First, create a mount point if you haven't already:

   sudo mkdir -p /mnt/combined_storage
   

2. Run mhddfs with sudo (mounting requires root privileges) and specify your partitions correctly:

   sudo mhddfs /dev/sda2,/dev/sdb3 /mnt/combined_storage
   

   Important Note: If either /dev/sda2 or /dev/sdb3 is already mounted elsewhere, use their existing mount paths instead of the device names. For example, if /dev/sda2 is mounted at /mnt/sda2 and /dev/sdb3 at /mnt/sdb3, the command becomes:

   sudo mhddfs /mnt/sda2,/mnt/sdb3 /mnt/combined_storage
   

Step 4: Troubleshoot Further If Issues Persist #

• Reinstall mhddfs and FUSE: Corrupted installations can cause odd behavior. On Debian/Ubuntu-based systems:

  sudo apt remove --purge mhddfs fuse
  sudo apt install mhddfs fuse
  

• Check kernel compatibility: Most modern kernels support FUSE out of the box, but if you're running an older custom kernel, you may need to enable FUSE support during kernel compilation.
