 ### 2. Implementation Strategy

 1. **Clean the Pool:** Use `rmlint` to clear duplicates and reclaim space.
-2. **Identify the Parity Drive:** Choose your largest drive (or one equal to the largest data drive) to hold the parity information. In my setup, `/mnt/usb` (sdc) was cleared of 4TB of duplicates to be repurposed for this.

+2. **Identify the Parity Drive:** Choose your largest drive (or one equal to the largest data drive) to hold the parity information.
+3. **Configure MergerFS:** Pool the data drives into a single mount point.
 4. **Configure SnapRAID:** Point SnapRAID to the data drives and the parity drive.

 ### 3. MergerFS Config (/etc/fstab)

+On majorhome, the pool mounts three ext4 drives to `/majorRAID`:
+
 ```fstab
-# Example MergerFS pool
-/mnt/disk*:/mnt/usb-data /storage fuse.mergerfs defaults,allow_other,cache.files=off,use_ino,category.create=mfs,minfreespace=20G,fsname=mergerfsPool 0 0

 ```

+Adjust the source paths and mount point to match your setup. Each `/mnt/diskN` is an individual ext4 drive mounted separately — MergerFS unions them into the single `/majorRAID` path.
+
 ### 4. SnapRAID Config (/etc/snapraid.conf)
