Technical challenge for RNDU4000 Ultra 4 (#16372263)
Ok, here's what I am faced with. I had a perfectly fine ReadyNAS Ultra 4 with 4 x 3 Tb drives running 4.17 with about 3-4 Tb of data on it. I moved it to a new lan with different IP arrangement an...
>The os and config are stored on the drive(s), not in the firmware flash.
in other words, the 80gig drive is completely irrelevant to the 4 drives with your data.
Did you pop out the drives while the nas was running?
Yes. If i didn't, i was risking that it would start to format my discs. The screen indicated it was installing firmware, and i did the quickest thing possible to stop the process.
>If so, then mostly likely are out of sync with each other (meaning that the data striped across the drives is no longer consistent and possibly corrupted).
Wouldn't that be the case on if data was being written?
>If you are lucky and they are not out of sync, or you shut down the nas before removing the drives, it may be possible to boot up in tech support mode and let support remote in and disable the factory default commands/config and hopefully get the array back up and mounted.
That sounds like a plan.
>I would recommend posting your support ticket # to the post topic and let support get involved.
I did
>Your data could already be gone, or it could be salvagable... so don't do anything that might make it go bye bye.
I sure hope not. I am doing nothing, waiting for someone who knows exactly how to proceed before I do anything. Right now i have the spare 80 Gb in the RAID and it is up and running.
>Another possible way, if you are knowledgable with linux and linux software raids, is to attach the 4 drives to a linux box and try to get the /c volume mounted without being in the nas.
That is a last resort tho.
Ok
>Hopefully you can avoid the painful lesson losing data, that raid is not a substitute for backups.
I know of course. But i have no easy way to back up 4 Tb of data without a 2nd RAID.
