[Plugin] [Support] Windows Dynamic Disks (ldm-unraid)

Support thread for Windows Dynamic Disks, a plugin that reads Windows dynamic disks (LDM) on Unraid.

When Windows makes a spanned, striped or mirrored volume it converts the disks to "dynamic". Unassigned Devices only sees the raw pieces of those, so the volume can't be mounted. This plugin reads the LDM database Windows keeps on each disk, rebuilds the volume with device-mapper and mounts it under /mnt/disks.

What it does

• Simple, spanned and striped volumes on MBR or GPT disks

• Mirrored volumes, read from one copy (works with one disk missing)

• Read-only by default, read-write if you ask for it

• Optional SMB share per volume, public or per user

• A section on the Main page plus the ldmctl command-line tool
  Not supported: RAID-5 volumes (Unraid's kernel has no dm-raid) and ReFS.
  

Plug in all the disks of the volume and it shows up under Main, Windows Dynamic Disks. One warning: don't mount the individual pieces in Unassigned Devices. The first piece of a spanned volume looks like a complete NTFS volume, and writing to it will damage the real one.

When reporting a problem, please include the output of ldmctl status --json, your Unraid version, and what Windows showed for the volume in Disk Management.
