ReadyNAS 314-RAID 1 Volume Issue
Bit of a novice so the problem maybe of my making but need some advice.
I have a ReadyNAS with a WD Red 3TB drive in it. I had around 500GB of space left so installed a second WD Red 4TB drive. After the ReadyNAS had integrated the drive in RAID 1 configuration, the space available still shows at 500GB?
Why does the additional 4TB storage not show up in the volumes panel on the ReadyNas admin page?
thanks
Welcome to the Community!
This is because your RAID configuration uses X-RAID and by this the system automatically used the 2nd drive you inserted to be used as protection/redundancy.
RAID 1 uses mirroring which copies the first drive and becomes a replacement in case of a drive failure.
What you can do is to add another drive on your current configuration for it to become RAID 5 which adds additional data capacity to your NAS and still provides protection. Another way is to disable X-RAID on your volume and add another disk and set it as JBOD. You will have 2 volumes this way, your current RAID1 setup and another volume which is JBOD. Do note that this does not have any protection in case of failure.
It is always best to set backups of your data in different storages so in the event that you may need to do a Factory reset or failure, you still have copies of your data.

RAID-1 is mirrored (providing redundancy). So the capacity doesn't increase when you use it.
If you upgrade the 3 TB drive to 4 TB, the volume will increase by 1 TB. A better strategy (since you have 2 empty bays) is to add another 4 TB drive. The volume would then increase to 7 TB (~6.3 TiB). The capacity rule with multiple disks is "sum the the disks and subtract the largest".
Either way, it is wise to make a backup before manipulating disks. A disk failure during the expansion will often result in data loss.

Great advice, thanks very much
I have a ReadyNAS with a WD Red 3TB drive in it. Added a WD Red 4TB drive in bay 2 and this successfully set itself up as a mirror. Tried to add a 2TB WD Red to bay 3 and get the response "failed to expand volume with disk model from channel 3; volume requires drive capacity to be the same size or larger before volume expansion can begin".
How do i solve this problem and get the NAS to accept the new 2TB drive; i was under the impression that you could drop any size drive in and it would increase the volume size?
thanks

No. You can add a size that is (or was) in the array, or you can add a size that is larger than anything in the array. But if your array never had a 2 TB drive in it before, you can't add one now.

There are two ways.
- Back up the data, do a factory default with all drives in place, reconfigure the NAS and reload the data from backup.
- Switch to flexraid, and create a second volume for the 2 TB disk.
With option 2, you'd have to create some shares on the volume to use the space (perhaps moving some existing shares). The 2 TB volume won't be protected by RAID redundancy.
Personally I wouldn't bother. Instead get another 4 TB Red and add it to the array instead.
