March 2, 201610 yr Hi there I was having a great time with UNRaid until I added a new disk and since then the network speed is extremely slow. I had my system up and running with the following drive config: Parity: 6TB Drive D1 : 3TB Drive D2 : 3TB Drive D3 : 3TB Drive D4 : 3TB Drive I then preceded to set up the shares and move my data onto the drives. I was getting 60MB/s across my gigabit network (pretty happy with that). Then once I had move about 6TB onto the NAS I had a new disk to add onto the system in Disk position 5. I stopped the array but the shutdown sequence got stuck and I could not do anything. So as there was no one accessing the system and no dockers etc running I rebooted the system. When it came back up the new drive was visible and I added it too the array. It took 10hrs to clear the new 6TB disk and then the array was online again. But after that the network speed has been about 900KB/s or less. I keep getting an alert in the browser saying that the array has failed but I can't see any error anywhere else to tell me what is wrong. Any ideas or help would be appreciated.

For example I noticed that a number of your shares are set to shareInclude= "Disk 4" only and have "shareUseCache=" set to no? This would mean to me that in a number of those shares, those shares are using Disk 4 only and they are bypassing the Cache disk therefore writes are being made direct to the Parity Protected Array and you would expect writes to be no more than 40MB/s. If settings are similar for other shares / disks then this "might" account for the slow speeds. Ill continue going through the logs and settings.
March 2, 201610 yr Author Cheers for looking but yeah have a number of shares that only use disk 4. The Video share uses all but disk 4 as that has the most files. I would love to be still getting 40MB/s but sadly only getting less than 1MB/s. Also I will turn on my cache disks again once I have all my data back on the array. I found out the hard way how the cache works when I filled it up and the 3TB transfer stopped after 120GB..
March 2, 201610 yr Community Expert Also I will turn on my cache disks again once I have all my data back on the array. I found out the hard way how the cache works when I filled it up and the 3TB transfer stopped after 120GB.. When you set up to use the cache disk for our shares do not forget to set the Min Free Space to be at least as large as the largest file that you intend to transfer. At least that way if you do fill up the cache disk so that the free space falls below the Min Free Space value subsequent files will go straight to the array disks (albeit slowed) rather than failing the copy.
March 3, 201610 yr Author OK so it turns out it was the network switch. I had a D-link Gigibit switch connecting everything which I replaced and it has come good. Thanks for the help.
