HDD / Storage Area Monitoring & Management

[marcoherbst]

We want to know things like:

• Serial # and physical characteristics ( Capacity, model etc.) https://unix.stackexchange.com/questions/121757/harddisk-serial-number-from-terminal
• Remaining Space & Time to Full (Days).
• Allocation of Storage areas for different processes & cameras.
• Health (Bad sectors)
• Alerts for Bad Health or LImited Remaining Space.
• Formatting & FileSystem Management

I'd be ready to have a debate about only limiting scope to logical storage areas, but I'm currently leaning in favour of ExNVR also dealing with Physical Storage.

Seeing the Erlang docs, maybe the easiest implementaiton is just whatever we can get from this;

#356 similar to this issue.

Related to #331 and #257

Much of the urgency of this is dealt with now by using Grafana.

Part of this task is to get the HDD Serial number. We noticed that for USB attached HDDs we are getting a different number reported as the HDD serial, it seems to be related to the USB-to-SATA chipset, not the drive.

There is some talk of this in forums and some discussion of getting the actual HDD serial via the SMART readings from the USB, where available.
