Ok here is what I've planed in more detail:
Win7 x64 (host):
--- 3 physical data disks shared for share client
------ disks merged with liquesce for local use only
--- virtual box with Win7 x86 32bit (share client)
------ 3 shares merged with liquesce (32bit)
--------- share of liquesce drive for all (should work since it is 32bit)
Hope that is making it clear.
To the linux idea:
I already had my server running linux only. I think I tested nearly every disk merging tool for linux (there are many instead of windows) like mhddfs, ufs, aufs and other fuse implementations, amahi and so on. With none of them I was really happy. By the
way some have also sharing issues ;). Some are just buggy. And some can't be configured flexible.
The other thing is that I have only windows machines on my network so a windows server would be more comfortable. With running linux in a vm I would run in the same troubles. Also the allocation modes would be inconsistent if liquesce and an other tool are
running parallel. Good Idea, but I already had this torture and I take windows ;).
And the reshare question:
If the sharing works on a native win7 x86 then it will work in a virtual machine also. even if the sourcelocations are shares on a other pc (in our case the host).
I already tested the use of shares as sourcelocations and it worked without a problem. So we will see.
