Is it possible to disable reoccurring read checks? I was looking for its schedule and was not having any luck finding it.
-
Weirdly, I shutdown added more RAM (it's a VM) and it powered on. 3GB->4GB.
-
So being new with UnRAID I thought that the backups went to the cloud and indeed they do not. I upgraded for 6.10.3 to 6.11.0, and now I am in a endless reboot. I get to `Loading /bzroot...` and then the machine reboots.
I did not have any plugins or config other than a single share, but I wanted to see what else i could try before wiping starting over. Starting over, so i just pull the USB stick and reinstall it from a Windows machine?
-
I took the advise of removing parity, as I didn't actually know this was an option. I now have the speed i was hoping for. Thank you! I'm now hitting over 250MB/s on a single transfer to a single drive.

Yes, it is virtualized with the HBA Adapter in PCI Passthrough to the VM.

So I don't believe it will keep up with it writing to drives after written to cache., or offer much of a speed improvement if the writes are constant. I was thinking of getting some cheap 1TB drives.

I will say the community support is great so far. Thanks for all the responses and feedback.
QuoteThis will disable "turbo write", keep writing one file only.
I got it. I have two machines writing, so that isn't quite possible.
QuoteWon't that low for mid-high grade NVMe.
What I means is once a SSD fills, wont it write directly to the disk?
QuoteAlso apply to Unraid if you use software RAID by pool / UD.
How does this work?
QuoteThis won't happen, array throughput won't over single disk throughput, so for spinner disk usually in 140MB/s - 90MB/s. If you have enough RAM cache, then network transfer to RAM will saturate the 10GNIC ( 1GB/s ) and it will "slowly" writing to array.
So If If I give the device more RAM, I will see better speeds? My goal is ~150-200MB/s with two device writing and one device reading.
QuoteRequire all drives be the same size, and if you lose more than parity can recover you have lost it all.
I understand, I went with UNRAID to save 16TB, but seeing the speed is making me think I might want to take the hit.
QuoteUnraid is not RAID, you'll never get same speeds as other solutions that stripe drives, you can have fast pools, array will always be limited by single disk speed.
What are Fast Pools?
To add, with one write, I still am not hitting the ~145MB/s one drive is capable of:
-
So let me ask the question. Why would people use UnRAID if it is so slow? I have new 16TB and 18TB drives. If I drop one more drive to Parity for RAID5 against the 18TBs and 16TBs, I could achieve 8x the speeds of unRAID. How are people getting speeds of 1GBs? Is it all due to NVMEs? What happens when writes are sustained? It goes from 1GBs to 90MB? Windows software raid can reach much higher speeds.
-
With the array healthy and "Turbo Writes" on, I still cannot saturate a 1GB when writing two files, to two different drives. I have notice maybe 100Mbps faster with "Turbo Mode". During rebuild the drives each did 150MB/s.

Thank you for the response. I have disabled all writes until the rebuild is done and have enabled that "turbo mode." I will test once the rebuild has completed and report back.

I have a Unraid with dual Samsung 850 Cache pool and a mix of 16TB and 18TB drives. I have it running on a VM in ESXi. It has a 10GB NIC and another VM has a 10GB NIC. Moving a single files is only hitting ~600MBits/s. I have a JBOD HBA directly attached within the VM and that's how all HDDs & SSD Are connected. I noticed that the SSDs are not being written to and even if it it direct to the drive, i would expect it to hit higher while using the drive cache, and even writing direct once drive cache is full.
I have a old dell with a few externals on it and that can saturate the 1GB link with this same one file to a single external 16TB drive. So I'm confident this should be getting equal or better performance.
I've notice that the device is not using cache, but even direct to disk it should be able to handle this as the drive can hit over 120/MBs for a synchronous write.I've noticed that when I use another machine to transfer a single file, which looks to be hitting a different disk, it still only hits 600-700Mbps. Is there something wrong with the setup?

Disable read-check
in General Support
Posted
So I don't have parity drive, so a read check tells me there is a problem I could never do anything about, so I disable it. It also causes spiked latency when it is running.
