I’ve just found out that the management password of my storage node has been truncated by 1 character. After typing it again, everything is back to normal.
That version has definitely changed my password 
Well I’m not sure my problem is related to the one described above, sorry for that. 
Morning,
Have you tried to update kernels of your FOG Server guys? To do so, you click on “Fog Configuration” then “DefaultMember FOG Version” to display both running kernels (mines are 5.15.19 for example).
Then you click on Kernel Update in left panel. You pick those 5.xx.xx kernels Intel 64 Bits and Intel 32 Bits and download them to start the installation process.
You probably need a 5.xx kernel and don’t have it installed.
Let us know if it works 
Hey guys!
It looks like it works so far. I tested with 2 fresh installations of W10 1803, one in MBR and the other one in UEFI and each capture has its own d1.fixed_size_partitions populated.
Content of these files :
MBR => :1
which is the partition labeled : Réservé au système
UEFI => :2:3:1
Which are Recover, System, MSR
I will do more experiments soon but I like what I saw ^^
Thanks for the good work
