Can't access NAS - password fail - and not showing up on TV

Hi all,

Firstly, thanks for any help you might be able to give me.
Mods - please move this if it needs to be in a different forum, I looked, but I couldn't work out which it needed to be in, it didn't seem to fit anywhere... :oops:

I have an Ultra6 NAS (RNDU6000 ReadyNAS Ultra 6). It's replacing a 2-bay unit that got fried in a lightning strike (lightning hit the power pole outside my house and fried the phone line. All the power-boards had spike-detection, but, unfortunately the phone line didn't. The strike fried the modem and everything attached to it via Cat5 cable)... But I digress...

I got the NAS a few months ago, but, we've just moved house so I haven't had a chance until today to really do anything with it. I plugged it in, but, didn't use it.

The NAS is connected to a NetGear switch via Cat6 cable. The switch is connected to the modem. (The modem is in our study, and we have Cat6 access points all around the house - thankfully the house's owner does cabling for a living! lol) - anyway - also connected to the switch is my CPU (named Cougar) and a WDLive media box.

When I had my old NAS, I could 'see' it on the network as if it were just another drive. I could move files onto and off it, again, as if it was just another drive, and it didn't ask for a password.

Today, I tried to get into the NAS, and I can 'see' it on the network, but, when I try to get into it a popup box pops up saying "Windows Security" "Enter Network Credentials". It gives me an initial account of "COUGAR/NAS-BOX" and asks for a password. I've tried all the passwords I usually use for things (even made up a few others, however, nothing worked.

I have also logged into the management system of the NAS but I can't see anywhere there where I can remove the requirement to log in with a password...

Under "User accounts" it says no accounts found.

In the Network settings it says the status of the unit is 'Offline'... and the NAS doesn't show up on the WDLive unit's interface (on my TV).

The way I want my system to work is that I move completed files from my CPU onto the NAS, then I access the NAS from the computer to watch shows.

I would appreciate any thoughts you might have.

Thanks :)

    The 4 disk minimum is raid-6 (dual redundancy), not raid-5 (single redundancy).

    The default xraid blends raid-1 and raid-5. So no matter how many disks you add, you have protection against one disk failure. This mode works well for most users. Each disk you add needs to be at least as large as the biggest disk you have installed.

    There are two caveats though - You can't grow a volume more than 8 TiB from your starting point, and you can't expand a volume past 16 TiB (no matter what your starting point). Since you currently have 2.5 TB, you can expand to about 10.5 TB before you reach the growth limit. At that point you'd need a factory reset. The other option is to get more drives now, and do the reset up front.

    Multiple drives failures can happen in rapid succession - not very often, but more often than random chance. After all you are putting several near-identical drives into the same chassis under near-identical loads... However, if you are keeping an on-site backup and crashplan, then you still wouldn't lose data even if this were to happen.

    Also, with the ultra (running 4.2.x firmware) you can move to dual redundancy easily (starting with the insertion of disk 4) - as long as they are all the same size. For example 6x2.5TB with dual redundancy would give you 10 TB of storage.
  • OK, so, if I go with the RAID-5, and I have one 3TB Seagate Barracuda drive available to put into the system (just have to get the data off it), and I buy one more 3TB drive, and put the two in right now, before I reset the system and change the RAID... That will give me 11TB now, then allowing two more drives to be installed later.

    So, I’ll see how I go, financially and add two 3Tb drives if I can, otherwise I’ll just use the one I have and add the other later.

    If I understand correctly, as it’s now on xRAID2, once I add a third drive it’ll automatically go to RAID-5. So, I’ll probably just add one 3Tb drive (that I already have) now, then add three more 3Tb drives as I go along. I know that means that I’ll be “wasting” 1Tb as I’ll be over the 16Tb limit, but, as I can’t buy 2.5Tb drives anymore (there aren’t any in any of the retailers I usually use), that’s my only option, as I can’t put 2Tb drives in because “you can’t add a drive smaller than any of the drives in the unit at the start”.

    StephenB, I can’t thank you enough for your patience and help while I got my head around all this. THANK YOU so much. As soon as you confirm (please) that I have this right, I’ll set about dropping all the data off the 3Tb drive and then add it to the NAS.

    2x3TB + 2x2.5 TB would give you ~8 TB of storage (7.27 TiB reported in Frontview). (the rule is to sum the drives, and subtract the largest). If you do a reset now (which will destroy the data, so you will need to restore from backup) you will be able to expand to 6x3TB later on - (~15 TB of storage, or 13.6 TiB reported in frontview).
  • Thanks. I am going to do a reset before I start. Now just to go find some space to empty that 3Tb drive! lol

    I really have appreciated your help through this. Thanks again.
