RNDU6000 won't boot - faulty PSU or bricked NAS?
Hi everybody,
I have a Ultra 6000 which has been performing flawlessly for about three years now. I recently upgraded my drivers to 6 x 4TB and that whole process went quite smooth. I lost some data but that was my own fault, not Netgears. However, I did begin to notice (and this might have started before the upgrade) that the NAS occassionaly shut itself down. I'd wake up, try to upload something to the NAS and the FTP software would say it couldn't find the NAS. I'd check on the machine itself and it was just turned off. After turning it back on, it would be fine again. This situation did start to get worse over time, up the point where I am now. Which basically means the NAS has stopped working. When I now turn on the NAS, it either shuts itself down within two seconds or so, or it will stay on, the word 'ReadyNAS' will be displayed but that's it. It won't boot. I can't access the boot menu either. This is very upsetting because I can't access the data which is on the NAS. I know, back it up..but it's hard to back up 10+ TB ;-)
So,I ruled out memory. Can't access boot menu. USB boot recovery also won't work. So I'm looking at either the PSU or an unidentifyable problem. If it's the PSU, I can simply buy a new one and replace it and that's it. Just need to figure out if it actually is the PSU. That's gonna be hard. But let's say it's not the PSU and my NAS is definitely bricked. The drives itself and the data on it, should be fine. I might be able to buy a RNDP6350, which also has six bays. Would I be able to migrate my discs from the RNDU6000 to the RNDP6350? I know it depends on CPU architecture, but I can't find out for sure if they have the same one or not. So I'd appreciate it if you guys can verify this for me.
Also, of course, I'm open to any other suggestions regarding my problem. Also, maybe as a symptom, when I try to boot the NAS and it actually stays on, the fans never go to a lower RPM. Could a faulty PSU cause the NAS to shut itself down and/or not properly boot? I read somewhere at the NAS checks if the PSU is putting out the right volts and amps, and if it doesn't, it won't boot.
Please let me know if you need any more information.
With best regards,
Ruud

- Have you double-checked your warranty status? If you joined the forum when you purchased the ultra, you have a month of warranty left.
- I think I'm 2 months out of warranty -- but it'll take days to track down the exact purchase date through the university's purchasing system. However, I have a brand new RN31600 that's 100% under warranty but can't boot from the old disks, contrary to what tech support told me yesterday when I contacted them.
Well I did tell you that wouldn't work. :shock:mazerj wrote: I think I'm 2 months out of warranty -- it'll day takes to track down the exact purchase date through the university's purchasing system.

Hmmm.. yet, but netgear tech support and mdgm both said it would...- Not sure about L1 tech support, but mdgm almost certainly said you could migrate to another pro or ultra, and that Netgear support could assist you in migrating data to the RN316. That's what he's said several times to other posters. The RN300 (and all OS6 products) are very different from the OS4 firmware running on your ultra.
I think you should check the warranty status quickly as you can - if you registered it, then you might be able to get the data from netgear's support site. - Unfortunately, there's no way to get the info until next week.. the person who can get in my business office is gone until then. In the mean time, I'll call tech support this afternoon and see if they are willing to help me do the migration since it's onto a brand new machine that's definitely under warranty.

StephenB - I just got off the phone with support and they confirm what you said -- the 316 can NOT read drives formatted under Radiator4.2.x or boot from them. They have no idea what either tech support or mdgm were talking about yesterday. However, apparently I can pay $200 for their advanced data recovery service and they'll have a tech remote in and recover the data for me so I can copy it off. This seems to indicate OS6 can read ext volumes, but they won't tell me how to do it.
I feel like I'm missing something obvious here -- I'm thinking there is an ext4 module available or installable, but it's not loaded by default. With a loadable ext4 module I could boot OS6, insert 5/6 of the old drives and then use mdadm to mount the old data (only need 5 of the 6 since its RAID5). And it certainly sounds like I'm not the only person who's had something like a PSU failure on a 4.2.x machine leaving the data nominally intact, but inaccessible..- I don't know the process exactly is. You need to get the NAS to boot somehow (perhaps installing on a scratch disk?), and then manually mount the others (perhaps inserting all but one into the chassis?) ext support is built into the RN316 kernel, so reading the disks isn't a problem.
Once mounted, my guess is that you'd need to copy the data somewhere else, reset everything and then restore the data.
You are correct in thinking that others have had dead ReadyNAS and wanted to migrate to OS6 systems. First I've heard that there is a charge for this service. - StephenB - I think I'm on the right track now, I booted to OS6 off a spare drive and now I should be able to ssh in and use LVM/mdadm to manually assemble the raid volume. I just need to poke around to figure out the partitions that contain data (vs os) and the right mdadm incantation (I'm a bit rusty there - that's why I'm BUYING nas's and not building them myself anymore..). This would work if the drives weren't redundant since I'd need to get all 6 in there...

Well the tech you spoke to today is wrong if he said that. It can boot from it if the array is fine. An x86_64 system (i.e. 300 series, 516 or 716x) can boot 4.2.x. Our head dev has put code in the firmware to handle this situation. We have an internal article on this.
Of course if there is a problem with the array or an issue on the OS partition this will remain when you move the disks across and the NAS will fail to boot.
Do you know what version of OS6 is on the 316?mazerj wrote:

A tech remotely logging in is only necessary if there is a problem with the array and OS6 thus can't boot 4.2.x.mazerj wrote: StephenB - I think I'm on the right track now, I booted to OS6 off a spare drive and now I should be able to ssh in and use LVM/mdadm to manually assemble the raid volume.

If you want to do it that way, you need to do some things e.g.
# systemctl stop readynasd
# systemctl disable readynasd
To make sure the NAS does nothing with the disks from the 4.2.x box. If you break things trying to recover data yourself we may deny support.
