Raid 5 disks have become inactive
Hi
I own a ReadyNas 104. And I was recently stupid enough to pull both disks at once. Upon reinserting them, I now get errors. "Please remove inactive volumes to use the disk. Disk #1,2. They show as red in the volumes interface. Raid 5 is detected as is their size, but they are completely unusable at this point. The only action I have at this point is 'destroy' and 'format'.
I desperately need help in recovering from this, or at least get some of the data back. I have larger disks that can be used to back up the data if need be before trying anything. Any help is welcome!

- Perhaps try powering down, then inserting the disks with the NAS off. Then power up and see if it recovers.
- You don't have a backup I assume.
Did you remove the disks while the nas was on? Did you reinsert them while the nas was on or off?
You can try what StephenB has suggested, if it doesn't work your best course of action if there is no backup is to contact Netgear support, you will probably have to pay for data recovery. - I initially reinserted them while the nas was on. I was under the assumption that inserting disks was ok when the nas was on?
No, quite the contrary. An OS4 ReadyNAS would have wiped your disks. OS6 added some safeguards to prevent that.3xil3 wrote: I was under the assumption that inserting disks was ok when the nas was on?
The NAS assumes that you were replacing disks, not reinserting the same ones - so it wants to rebuild the array. If you make this mistake again, power down and then reinsert the drives (in the original slots is best).- Ok, that was completely unknown to me. I've followed your suggestion of placing them in the original slots. Unfortunately, the situation stays the same.
Is there no way that I can connect them to my windows machine and attempt to recreate the raid 5 there, or at least get some of the data off? - Your best option is to contact support.
