Thanks again Joey. My progress is detailed below. I can run/collect more detailed scenarios if it will help.
Summary:
Success with a VM on qemu.
Failure with VMs on hyperv.
* Hardlinks are not created for the VMs on hyperv, in spite of the VM filesystems being ext4.
* This may only be associative, and not causal, but it is somewhat surprising. Yet, I am no hardlink expert.
* I can however make it work if I use a VM on qemu, so far; so that is very good.
Setup:
* mkdir gitx1
* git init
* git annex init --version=6
* git config annex.thin true
* git annex fix
* copy bigfile to gitx1
* git annex add bigfile
* git commit -m add
* ls -li
Test Procedure:
* unlock bigfile
* ls -li
Pass criteria:
* ls -li shows 2 links and the inode matches the SHA file inode in annex/objects/
* gitx1 dir size is equal to one bigfile
Fail criteria:
* ls -li shows 1 link and the inode numbers are different: working dir compared to annex/objects
* gitx1 dir size is equal to 2 bigfiles.
Scenario 1:
* VM arch linux
* git-annex: 6.20160613-g1e4e6f4
* Host: Centos, qemu
* gnome-disk-utility: QEMU HARDDISK (1.5.3)
* partition: MBR
* file system: ext4
* Result: Pass
Scenario 2:
* VM arch linux
* git-annex: 6.20160613-g1e4e6f4
* Host: Win10, hyperv
* gnome-disk-utility: Msft Virtual Disk (1.0)
* partition: MBR
* file system: ext4
* Result: Fail
Scenario 3:
* VM Debian 8.5
* git-annex: 6.20160524+gitg2b7b2c4-1~ndall+1
* Host: Win10, hyperv
* gnome-disk-utility: /dev/...vg/root
* partition: lvm
* file system: ext4
* Result: Fail
