- Fixed 4 broken markdown links (bad relative paths in See Also sections)
- Corrected n8n port binding to 127.0.0.1:5678 (matches actual deployment)
- Updated SnapRAID article with actual majorhome paths (/majorRAID, disk1-3)
- Converted 67 Obsidian wikilinks to relative markdown links or plain text
- Added YAML frontmatter to 35 articles missing it entirely
- Completed frontmatter on 8 articles with missing fields

 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.

+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)
