Hi,

 

I have 3 different NVME pools on my main server as pictured.

All tests have been done using midnight commander.

If I copy between any of the pools using /mnt/cache - /mnt/cachetwo - /mnt/Nvmepool I get 450-500 mb/s which is great, but if I copy from any of those pools to a user share I only get around 150mb/s ?  

I don't understand this as the shares are set to use the NVME cache pools and parity drive is not being used when writing to the pools so why are file transfers slower when writing to user shares?

 

Any guidance would be very appreciated!

User shares always add some overhead going through FUSE, set the pools to exclusive if possible, and you can still use the user shares and will bypass FUSE.

What precisely do you mean by this?

What part is not clear?

Thank you, so there is a reason, even though I do not know what FUSE is/is doing (I will investigate) Can you please enlighten me on the setting the pools to exclusive? I really do not know what you mean?

 

Thank you!

There is an option to enable Exclusive Share support under Settings->Global Share settings.    I would suggest you make sure you read the help built into the GUI for that setting to understand when it applies. 

Oh! After all these years, never noticed that! thanks!

It was added quite late in the 6.12 series of releases which is why you probably did not notice it the past.
