Use Cache while array is stopped (or Docker or VM)?

[plasticrake]

New to unraid, still in my trial.

 

My requirement is I'd like to run certain services (dockers and/or VMs) while the array is stopped.

 

My concern is that "critical" services such as home automation, network management may be down for hours at a time if I encounter any issues where I need to stop the array for hours at a time to fix. These services would not need to be on the array at all (just a cache disk or unasigned device), I'd just like to run them on the same box.

 

Any ideas on what I can do?

 

1) Run docker when array is stopped

2) Run VM when array is stopped

3) Run Unraid inside a VM and run my other services in a separate VM or in the host system?

 

Or is this not a likely issue and I'm overthinking this?

 

Thanks!

Can't be done.  Couple of feature requests already for this, but thus far nothing has come of it.  Probably due to underlying complications.

Unless you're changing the motherboard or something like that, downtime would usually be in minutes (time to change a harddrive / add memory, reboot, etc)

Situation hasn't changed, and I don't foresee it changing anytime soon.

separate docker/vms from the array would be a nice move.

I would need that too. Hopefully the devs will take that into their roadmap.

 

speaking of roadmap: is there something like that for unraid?
