Ok so i have bought a HP Microserver, upgraded it to 4GB on memory.

I have installed freenas 8 RC4 onto a flash drive. Gone into the webgui created a radiz ZFS volume which now shows under "Volumes" as /mnt/HP NAS.
But when i click on permissions for it i get "Sorry, an error occurred".

I have setup cifs and turned it on now and can see the device on the network but there is obviously nothing there to access.

So can somebody take me through this step by step.

Also i set the IP that i wanted via the console setup 192.168.16.4 but when it reboots it defaults to .189 i want it to stay as .4.

Cheers
 
Its ok, my create volume must have gone wrong on the first attempt. I reinstalled and done it again and the 2nd attempt went fine :)

Im getting 65MB/s transfers at the moment is there anything i can do to try and max that out?

ZFS raidz with 3 x 2TB drives.

That reading or writing? Theoretical speed of the array would be linear reads of about 150MB/s with 7.2k consumer drives.

What is the CPU use when doing the transfer? What is the MTU on your network which I assume is 1 Gig E? What protocol are you using?

Also, Why am I seeing people sticking piles of memory in these things and using them as a NAS? Only way you need that much memory is for a cache and then you should have a UPS.
 
yeah sorry it was writing to the nas from my server, reads are maxing out my Gb network which is the thing i really need.

Im running ZFS and Raidz1 so the memory is needed and my logs show im using over 3GB when writing to the NAS.

CPU usage does occassionally hit 100% but at the moment im transfering 3TB of data to it so its busy :)

Im serving to all windows 7 machines so im using CIFS and the MTU im not sure where to find it in my router (im guessing this is what you mean or do i need to check all machines?) but im pretty sure im at 1500.
 
The writes will be slower, drives write more slowly, but more importantly the parity in the raidz array must by calculated the the weak CPU. Sounds like performance is about as good as it gets.

The memory use spiking when writing is deeply concerning, it suggests there's a write cache, either disable that or buy a UPS. One power cut and you loose data that the host thinks it wrote.

Jumbo frames, look at how to set the MTU to 9000 on the BSD freeness, the Switch and your host. You've still not told us what protocol you're using, iSCSI really begins to benefit from jumbo frames on 10Gb/s Ethernet.
