Re: ReadyNAS Duo very very slow

Did you try eliminating any possible network issues by connecting the NAS directly to your PC? Is it happenning on more than 2 computers? Can you please describe your network layout?

Re: ReadyNAS Duo very very slow

The symptoms, especially the latest, suggests there's a strong possibility that one of your drives is bad.

I expect that the NAS is currently resyncing a drive which is why you cannot access the web interface (resync is resource intensive and so can cause web access to time out plus you have the single flashing LED). You can verify by using the RAIDar utility.

You would be advised to test both disks using vendor tools - what drives are installed in the NAS? Have you upgraded the disks or were they supplied with the unit? What version of firmware do you have installed on the NAS?

Re: ReadyNAS Duo very very slow

hi
The drive are Seagate 2TB 3.5" SATA3 6Gbs 64MB Hard Drive ST2000DL003

it is now doing a resync, after it said it was doing a file system check with give me this below

Thu Jul 28 11:38:15 GMT 2011 A SATA reset has been performed on one or more of your disks that may have affected the RAID parity integrity. It is recommended that you perform a RAID volume resync from the RAID Settings tab ( accessible in the Volumes page => Volume tab in FrontView ). The resync process will run in the background, and you can continue to use the ReadyNAS in the meantime.
Thu Jul 28 11:37:31 GMT 2011 Disk fail event occurred on SATA channel 2. If the failed disk is used in a RAID level 1, 5, or X-RAID volume, please note that volume is now unprotected, and an additional disk failure may render that volume dead.

these are the logs which came after i switch it back on

firmware on the nas is RAIDiator 4.1.7 [1.00a043]

But the thing runs very slow, i have been reading it seems to be a problem with windows 7 and the mtu values, which i have changed??

Re: ReadyNAS Duo very very slow

You stated that you have very slow performance even when directly connected to the NAS. That typically suggests 1 of 3 things

1. NAS fault - most commonly a drive issue
2. PC problem - often a driver issue, particularly for Windows users
3. Cable problem - they can and do break

I would suggest you check out all 3 as follows to establish a baseline before changing any further settings:

1. Check your drives using the Seagate tools - you would need to attach each disk to a PC via a SATA connection to do this
2. Do you have a RealTek based NIC? If so - search the forum for "realtek" and you will find many posts re. drive issues. If not, at a minimun make sure your drives are up to date
3. Retest via a direct connection using different cables to rule out the possibility that is the source of your issue.

Re: ReadyNAS Duo very very slow

In a cmd window type: ipconfig -all

In the output you should see something like this - the description field describing the NIC installed (In my case an Intel NIC)


Ethernet adapter Local Area Connection:
