Performance/Admin Page Access - Does available disk space affect access to the ReadyNas
Hi,
I have a ReadyNAS NV+ and it has been running well for a while. A while back, I got a warning about the fan failing so I took the NAS out of commission for a while and got a replacement fan. I also got warnings about increasing bad sectors on one of the drives so I replaced it. I use the NAS as intermediate storage for my acronis images taken from my servers. I can't remember at what point, but my jobs began to take way longer to complete than they previously. I think it was after I replaced the drive which a WD10EFRX - WD Red 1TB NAS Hard Disk Drive. My backups literally take 4 times as long to complete. I replaced the 2nd drive with an identical WD10EFRX - WD Red 1TB NAS Hard Disk Drive drive and it still slower than it was previously. Unfortunately, I can't find the original drives that I had installed in the unit when it was initially provisioned. Both of the disks are healthy according to the NAS, but performance is still slow. I updated the firmware on the NAS. There is nothing in the logs apart from the occasional volume running out of space, which is normal in my situation. The NAS is connected to a 1Gb/s full duplex port. At one point I connected the NAS directly to the same switch that the servers are connected, however I saw no speed difference. There are 2 drives in a Raid 1 configuration.
Any assistance would be greatly appreciated.
Thanks in advance.
Are you using jumbo frames on your network?
It is a bit odd that you can't change the MTU. Perhaps try turning jumbo frames off, and do another test.

Hi StephenB,
Turning off jumbo frames and switching the MTU to 1500 seemed to do the trick. The backup now takes significantly shorter than it used to. Performance is 85% back to the way it was when we first got the device. I can't remember if I had jumbo frames on when I initially got the device. Thank you both so much for your help!!!

Hopefully it will last me a while. LOL.
Hi DaneA.
It was hard to just mark one as the accepted solution, but it was a combination of suggestions that he made which got me the result I was looking for. A combination of checking my speed along the links, plus the block size and performing a factory reset. Also it included disabling journaling on the volume plus disabling jumbo frames.
Thanks a lot for all your help.
