Are you copying to a cached user share?

Is that copying to the array or a pool? If to a pool which one?

may be i am not sure.it shoud be in the cache at the first

If that screenshot means 147 MB/s, that is very good for copying to an array with parity.

Whether or not a user share uses cache depends on the setting for the user share. Default is to NOT use cache.

Do you mean you have a user share named 'ssd'?

no,my cache is ssd,i creat a folder use cache only.the speed should be over 220MB/S,but it still shows 120-150MB/S.

the strange is the transfer speed is 270MB/S at the begining,then it came to 120-150MB/S

Try transferring to the pool with the NVMe device.

Then enable disk shares and copy directly to the NVMe disk share.

It's not writing to any device, maybe you grabbed the diags too soon, it can take a few seconds for writes to start while it's being cached to RAM.

Very strange, it's not device related since in one of the diags it was writing at 1.8GB/s, also doesn't look like it's LAN related due to iperf results and initial higher speed while it's caching to RAM, I'm stumped...

[xenoblade]

and i also got another problem,when i stop all array.add the nvme to the Array Devices.the all docker has been dispeared.how could i recover them

[JorgeB]

If you mean the docker image you can re-create it.
