How to disable OS/system writes on my storage HDDs as much as possible?

[u6f6o]

Hi,

I built my NAS with 6 HDDs for storage, 1 SSD for the OS and 1 SSD for jails.

My HDDs are constantly spinning and I do not use any power saving options, but I'd like to avoid writes from the OS to the storage HDDs as much as possible. Reading through some other posts I learned that syslog could be a potential problem.

So my question is, which configuration I'd have to apply in order to avoid writes to my storages HDDs as much as possible or are the system standards fine anyways?

Greetings,

Move the .system dataset to either your boot pool or your jails pool. Although repeated writes to your disks won't hurt them at all.

Unless you moved the system dataset, it won't write to your data disks. You shouldn't have to do anything.

I did not even realise before, but as I installed FreeNAS 10 beta, I had a look on my storage datasets which showed the following:

So there is some hidden .system folder as @danb35 pointed out.

My idea was to have the more frequent OS write operations etc. on the SSDs but you think I don't gain much advantage of this (in terms of power consumption, stability etc.)?

You really don't gain anything. But if you want to change it, in FN10, you'll find the setting under System -> System -> System Dataset Pool.

I see, if there is no reason for it, I'll stick with standard configuration.

You might not enjoy running freenas 10 in production just yet. It's still pretty beta.

Yes, I know. I built my NAS recently and did not have a "production ready" system anyways. As the news popped up that BETA is out, I decided to wait a bit longer and use it as a playground for the time being.
