Good day Rowland, in office again ;)

My servers are all Debian 10.6. I had the rare opportunity of rebuilding
most the office computer network in a single step, so I made it uniform as
far as possible.

The DC/NAS is built as follows.
. There are two large servers for virtual machines. both a re Linux 
In one there are VMware vmachines, in the other KVM.
. The DC is in a VMware virtual machine.
. The NAS is in a KVM virtual machine.
The reason for this is that the KVM let me access a physical disk
in the host, VMware doesn't. VMware machines were installed first.
. In the server containing the KVM vmachines
there is an hardware RAID-6 disk, which is then mounted only by
the KVM machine running the NAS.

I use only 1 filesystem for all the Linux boxes: ext4.

----- NAS : /etc/fstab (extract) ----------------
# -> this is the RAID-6
# mount disco /dev/vdb, corrispondente al fisico /dev/sdb
UUID="513fbb69-c147-41ce-87f1-8c1fa464c49b" /mnt/sambaShared ext4 
defaults        0       2
# -> this is the QNAP
# monto directory per i backup, specifica per questo computer
//backup.borghi.lan/backupDisk    /mnt/backupQNAP    cifs 
vers=1.0,credentials=/usr/local/etc/backupDisk.credentials    0 0
