Is it possible to have all disks get tested at once, instead of one after the other?

See the controller tests, look like this:

This is great, thank you. I just downgraded to a pcie 3 x1 port for the controller SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] so I could slot in a second GPU. So I expected it to be pretty bad, but not quite that bad.
It's telling me my simultaneous max throughput is 655.36 MB/Sec, shouldn't it be 1GB? As per the half duplex of the v3 x1 slot?

SAS2008 is PCIe 2.0, so with a x1 slot it would be limited to <500MB/s.

That's a good catch, thank you.
Price I pay for 2 GPU I suppose.
So then if it should be <500, why am I seeing 655?

You shouldn't, post the diags and the test result.

I would like to use this to test a RAID card in a pci slot, to see if it's bottle necking the drives when multiple are used at once.

You can do this by clicking on the  icon next to your controller.

 

Then click on the "Benchmark Controller" button. It will then read all drives attached to the controller for 15 seconds each in sequence, then all of the drives on the controller at the same time for 15 seconds, then display a graph showing both the isolated speed and the speed the drives got when reading all at the same time.

Hi, am I right in thinking that current multi drive arrays are not supported? Still seeing this message:

"This drive is part of a multi-drive pool or array."

Just wondered if there's any workaround to be able to test my NVME drives which are currently in a BTRFS RADI 1 pool.

I've added the extra parameter with the mnt/UNRAID etc.

Any idea why i would be getting more than the 550MB/s on a sata ssd?

I seem to be having the "Docker volume mount not detected" issue on my NVME drives (image attached).

I have already checked here, and the 'solution' says to add a path to the docker (also image attached).

However while that does trigger a rescan of the drives when booting up diskspeed, the error doesn't change. All four of the NVME drives are still erroring.

is there a dark mode avail, white background makes it unusable for me?

thanks

I have the exact same situation for my NVME Cache pool, all my drives show up, but say "Docker volume mount not detected"

how do you get benchmark cache drive

mounting /mnt

/mnt/cache_drive

doesnt let you scan it

Sorry, that is currently not available. It's on my To Do list but I haven't been able to spend much time programming of late, unfortunately.

There's something caching the read/writes and isn't honoring the cache bypass. The program uses FIO to do the benchmarking, try using a larger file size in the benchmark scan.

I'd like it too, it's on my To Do list.

Out of curiosity, does your nvme drive also have a dash in the name?

Do you mean the pool name if so then yes. My pool is "appdata-cache"

I too have the same problem with my nvme drives. Two in the cache pool and a third by itself. None have a dash in the name.

Click on the DiskSpeed icon on the UNRAID Plugin page and select "Console"

At the command prompt, run the same command, it should come back instantaneously but for some reason, it doesn't for you. You may have to wait a bit to get the true error that's happening at the OS - DiskSpeed tosses out a timeout error here because it's waiting for the OS to respond - and since it shouldn't ever toss an error here, I didn't trap errors so I could see it happen and know how to code a specific catch for it.

/bin/df -B 1KB

strange... it works for now... no changes made

Are ZFS pools yet supported?

Not yet on solid state devices. I haven't found a means to satisfactory bypass or mitigate ZFS's built in caching.
