FreeNAS 9.3 - Move system dataset to boot pool?

[Sir.Robin]

I made a 8GB boot mirror... and i want the System dataset moved from my main pool to the boot pool.

Can it be done?

I don't think this would be a good idea. Most people are probably using USB flash drives for their boot devices and constantly writing to the device will wear it out early.

 

[Sir.Robin]

Yeah... but if i'm not using USB drives... :)

Good question. Does it show as available in the drop-down menu of http://doc.freenas.org/9.3/freenas_system.html#system-dataset? If not, there's probably a good reason it is not.

Sorry to stir this up so long later the latest posting, but I've been looking into this as well as potentially moving the system dataset onto the mirrored slog I plan to implement.

I was wondering if you attempted moving system dataset onto your boot device and if so what your experience with this was.

It will work
But the death of the flash drive is imminent
Mine was dead in 4 months
It will be ok on an ssd
But I have read that it is possible to lose your pool if the system dataset gets corrupted
Do not hold me to this
Might be wrong
But redundancy for the system dataset should be considered

I plan to move to SSD if I were to do so, but I'd also ask how large was your flash drive. I'd think having a larger flash drive would also allow for better wear leveling, as 4 months sees ridiculously short.

The flash drive is an 8GB kingston dtse9 G2 as exact detail
I still have it
It sufferd an error
And while I was attempting to add redundancy to save me from reinstalling
It failed crashing the system

Well I just swapped out the two mirrored 32GB flash drives for a set of two 120GB 7200RPM drives in a mirror until I drop the cash on the SSD's

This question was asked at a time where there were no option in FreeNAS to do so.
Don't remember the exact version, but for several releases, you now have the option to choose what pool to put these datasets on from the "System-System Dataset" menu.

Been running it on boot pool since it got implemented and have had no issues. Boot pool is on a Intel G2 SSD though. :)

I presume, as FreeNAS lets you move it over there is no risk to losing the pool if the boot drive fails?

 

[dlavigne]

Correct. Refer to https://www.ixsystems.com/documentation/freenas/11.2-U5/system.html#system-dataset for what actually gets stored on the system dataset.
