My Unit is a Ready NAS Ultra 6 with Firmware 4.2.17, using Netgear's X-RAID2 . 6x HD of Seagate Barracuda 2TB 5900 rpm drives ST32000DL003 Position 6 has a red X and said HD died Replaced with HD from compatibility List a 2 TB Seagate Barracuda ST32000542AS bios CC32 (I have two of these). Also have WD 2 TB drives that are not in the list, WD20EADS (I have 4x of these for Or can I use a 3 TB Drive, Seagate Barracuda ST3000DM001 After removing dead drive and installing above drive, the NAS does nothing , like it does not see the drive (Hot swap). Again, How do you get the NAS to LOOK at the new drive? (I have already run Seagate's HD test on this drive from my computer) Thank you for your time, Kurt
From Log Window: Sun Dec 8 06:47:19 MST 2013 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. If this disk is a part of a RAID 6 volume, your volume is still protected if this is your first failure. A 2nd disk failure will make your volume unprotected. If this disk is a part of a RAID 10 volume, your volume is still protected if more than half of the disks alive. But another failure of disks been marked may render that volume dead. It is recommended that you replace the failed disk as soon as possible to maintain optimal protection of your volume.

All drives in RNU6 are the same with CC32, as you can see from hours, its been up for 2+ years. The problem seams to be with ST32000452AS drives not being recognized (on HCL and used by others). two were take out of another computer from Raid1, the raid partitions were deleted first (installing 1 in slot6).

I can try inserting the original drive back into the RNU6 The Original ST200DL003 Drives have been running since May 2011 with no problem, was on the HCL and then the only firmware was CC32. I see the link for the summer upgrade to new firmware in July 2012, more than a year later. The only way to get the firmware upgrade CC3D is to RMA all 6 drives back to Seagate, if they would take them and would mean loosing my data. One drive dropping out after 2 and 1/2 years is expected. What was not expected was NOT to rebuild when installing replacement drive. I will first back up what I can to a 3TB and a 4 TB drive first, not to loose any data. Which gets to replacement drives, Seagate Barracuda 7200.14 ST3000DM001 3 TB 6Gb/s 64 MB are 99$ and is on the HCL. Or are there better choices? Thanks Kurt
Question on Re-inserting original drive: Power-On: and it will format and rebuild Power-Off: Will it recognize it with the data and not rebuild (if dive did only fall out of array).? Thanks K
Yes, that's how this string started , by replacing the older drive with another newer drive. And then no rebuild with the 2 TB Seagate Barracuda ST32000542AS....
It took me so long to finish wanted to backup all data before trying rebuild and had to buy new HDs. I transferred 7 TB of data to 3 & 4 TB drive (and yes it would not fit, some is on SSD).
The data transfer was glacial at ~10 MBs (x-raid 5). Transfers from computer to computer are ~ 80 MBs and if its from SSD to SSD I get ~120 MBs. I remember ~60 MDs transfer on New RNU6 with x-raid 0 (2x 2TB HD Raid0). Why is the RNU6 so slow?
The rebuild can take a long time, especially when using high capacity disks. The disks have to be synced sector by sector and this puts heavy stress on all disks. It's not as simple as a drag and drop copy of your data. Also if you use the NAS for other tasks at the same time as a rebuild it can slow the rebuild down.
Also when a volume is not redundant performance can be a lot slower than normal. Performance should improve after both a failed disk has been replaced and the resync has completed.
Other factors that could lead to poor performance (may/may not be applicable in this case) include, but are not limited to: 1. Poor choice of HDDs 2. Configuration issue 3. If old firmware is installed you may be missing bug fixes, performance improvements and other enhancements available in newer firmware 4. If a hard drive is failing it could cause a performance problem

From the list. 1) HD were/are on HCL and transfers were in the upper 60 MB/s when it was new. 3) running 4.2.26 newest FW. 4) Health of system and Logs show no errors on any drives.
2) That leaves us with configuration. From RNU6 Configuration online/100Mbit/Full Duplex, Auto-negotiation, MTU: 1500 Services: CIFS and HTTPS Performance Options: Enable disk write catch, Disable Full data Journaling
Not sure why I have HTTPS checked, but Did I need something other than CIFS for Win7?
Thanks in advance for help that will get transfers back to normal. Kurt
No add-ons installed. I saw the status of 100Mbit/s I tried a different cat6 cable and port on my D-LINK DGS-1016D Gigabit Switch, still amber or 100Mbits. I tried a different cat6 cable and tied to Ethernet port2 on RNU6 and still 100Mbit amber on switch. Rest of the ports on the D-LINK DGS-1016D Gigabit Switch are green for the gigabit Ethernet. Also I have tried , connecting to AUSU gigabit Router directly to RNU6 still at 100Mb/s connecting a second switch, Roswell 8port gigabit switch and RNU6 still at 100Mbit/s
How have you configured it under Network > Interfaces? To get gigabit you need to configure it to auto-negotiate the network speed in Frontview. Make sure you haven't forced it to negotiate a slower speed.
yes, Network > Interfaces > speed/Duplex mode: "Auto-negotiation" The pull down arrow only gives me the choices of Full/Half Duplex at 100Mbit. There is no way for me to choose 1000 Mbit.?
Yes, I had tried the 2 Ethernet port, I swapped cables and ports on New switch2 with computer2, computer always shows 1000Mbit and NAS always shows 100Mbit..... Very Frustrating..... I am assuming both ports run off same controller, maybe a controller problem, if it was a computer I'd install a gigabit Ethernet card... Any root commands to set the ports to 1000Mbit?
Well, "ethtool -s eth0 speed 1000 autoneg off" would work. It doesn't change things permanently, so if it broke your connection you could reboot.
Did you try a direct connect procedure?
Also, if you are the original purchaser and purchased after May 2011, your ultra is still under warranty. If that is the case, you should open a support ticket at support.netgear.com.
Yes I had a support ticket and Mary was patient, final fix was to set Networking > Interfaces > Ethernet tab at bottom is Performance Settings (had to scroll down was not in view) check "enable jumbo frames". She said this was the only way to get gigabit Ethernet and it worked. So some where at some time it got switched off, not sure how or when, but now 3GB file is only 30sec instead of 30 min. Back up and running!
On a side note, wasn't sure if I wanted Netgear as a backup to my back up, I built a rig with 240GB SSD and 2x 4GB HD, not redundant but holds a second copy of my files.
I'm glad it is running, but the fix is a bit weird. Many people (including me) use gigabit without jumbo frames being enabled.
As far as backups go, I think you are wise to be maintain multiple copies on multiple devices. I maintain 3 copies of everything locally (primary, backup, secondary backup). I started that before I had a NAS, when I discovered bit-rot on a backup. I added Crashplan a couple years ago for disaster recovery.
Are you using the scheduled file consistency checks and disk scrub? I run the file consistency weekly, and the disk scrub every 16 weeks.
Yes, solution was screwy and failed. Some times its too much hard ware. I have 2 switches, 2 routers, 2 Computers, 2 NAS (D-Link too). But it came down to my cat6 cables, I think. With Jumbo frames on Reads were ~120 to 60 MB/sec (depends on file and SSD), but writes were ~16MB/sec. Without Jumbo Frames, all writes ~76 MB/sec.. I'll see if this stays. Thanks for the Advice, I now have 3x backup and will run checks (see if that improves writes). Thanks Again, Kurt PS when one moves a computer and or NAS, test the cables!
