Please remove inactive volumes in order to use the disk. RN104 #26317164
Hi all,
I have a RN104 which up until tonight I had been running without issue with 2x4Tb drives installed (Seagate NAS 4TB ST4000VN000), running a RAID5 configuration. As these drives were sta...
That's not the number to ring. Phone numbers to ring would be available through the support portal if still under support warranty or if you have the necessary support contract is in place.
When you added those disks your data volume array became a 4 disk RAID-5 array so we would need 3 out of 4 disks to be working to get at the data. Currently there are 2 out of 4 disks in the array.
So it depends on what you've tried and how far things have gone whether anything could be recovered. If the volume can't be mounted it's best to ask for help as the next step as the more you try the harder it may become to attempt to get your data back if it even remains possible.
Support would need to examine the disks and see whether there's any way of getting one of the disks that has dropped out back in assuming that is still possible.
Now whilst you could re-digitise your photos, CD's and DVD's due to the time involved this doesn't sound all that practical. Therefore you could consider the data on the NAS to effectively be as if they were the primary copy of your data.
RAID is great, but there are problems it cannot protect against including user error. See e.g. Preventing Catastrophic Data Loss
You shouldn't store important data on just the one device, and we recommend updating your backup regularly, especially before doing things like expanding your volume.
This website is littered with lots of people experiencing the same loss of data after upgrading to 6.4.0. I find it untenable that all of us, by chance, had multiple disk failures that happened to coincide with a firmware upgrade.
Hi gnubee,
Firmware upgrades do not cause hard drives to fail or get kicked out of the array. It is likely that these drives have uncorrectable errors in them and replacement is needed. NETGEAR offers assistance in trying to recover the data that's been lost in the volume that is no longer accessible. Again, the said service is fee-based and we do not guarantee the success of recovering all the data that's been lost.
Let me know if you have further questions.
Kind regards,

NETGEAR Community TeamSupport i find it very odd that I have installed 2 new drives in my 104 and am getting the same error message. What do you think stastically speaking that when you add drives that all the sudden you get errors. I am pretty sure it has something to do with the NAS and not the drives.
Hi ChiliDogLance,
Welcome to the community!
Were these drives listed in the ReadyNAS HCL? Since this is a 4 bay unit, did you try to expand by adding two new drives or was it a new setup?
Kind regards,BrianL

There are multiple possible causes of running into the inactive volumes problem. One of these is having multiple disk failures. There are other possible reasons why the data volume array may fail to start.
If you feel that a problem is a direct result of a firmware upgrade then be sure to mention that when contacting support, especially if you ran into the problem at the same time. However what is far more likely for a problem like this if you ran into it immediately after installing the update would be that there was a pre-existing problem (e.g. with a disk, perhaps) before installing the firmware update that led to the problem. Disks can and do fail at any time.
In any case if your data is important one would expect that you would update your regular backup before installing a firmware update, especially a major one (see ReadyNAS OS 6: Firmware Upgrade Guide and Tips) so in the unlikely event you run into a problem and you don't want to use support you could choose to do a factory default (wipes all data, settings, everything) with good disks in place (you could check the health of your disks e.g. using SeaTools for SeaGate disks) and restore from backup.
