You did right on changing the disks one by one and having them finish re-sync before replacing another. Have you had any warnings or errors before you changed the disks? What does RAIDar show when checking the status of the NAS? Kindly send in the logs through PM so we can check.
thank you for your answer. (My english is not very good, so I´m not shure whether I understand you. Ok, let´s try 🙂
I got no warnings
RAIDar is a special software, right? I downloaded and extracted ....but what to do now?? No *exe!!??
When I call the NAS in my Browser the system info says "Volume scan failed to tun properly" and (in german) "the paths to the shares can´t be found. This happens when ReadyNAS coundn´t reach the volume".
Does it matter whether the disks are in shaft 1 or 2 (I changed first 2 and than 1)?
I work with Windows10; downloaded RAIDiator 5.3.13 and installed it with the dashboard, "firmware update". Probably this was the wrong way; no more shares and no reports 😞
Maybe I´ll do best, repaeting the whole procedure. What do you mean?
.....Installing the one of the old disks (3 TB) and on of the new (6TB)....synchronizing .... and changing the second one.
How can I´m shure that the first synchronizing prozess is completed?
Did you changed the disk while the first one you inserted was synchronizing? You will be able to see that status using RAIDar. If you by accident replaced the last disk while the first one was synchronizing, getting the volume inactive will surely be the result. You should replaced another disk only after re-sync has finished.
Have you tried inserting the old disks and see if it will boot normally? if it does, you may want to retry replacing each disk or do a full Backup of your data, replacing all disks with the new one and perform Factory reset then transfer the data after finsihing setup with the new disk.
RAIDar shows two harddisks are ok., and system status is ok too.
In dashboard and explorer I can see the shares but no files within the shares.
> This is possibly because the 2 drives you inserted were formatted as a new volume
So it might be a good idea to insert one of the old disks and one of the new and let them synchronize. Right?
> Can you insert one of the disk without the 2 6Tb and see if it will boot normally? If it did boot normally I suggest doing a backup of your data then transfer it to the created volume from the 6TB drives
Two more questions:
Where can I see the first process is finished?
>When resync finishes it should notify you on the Admin page under volume tab or on RAIDar
Is X-RAID2 the correct modus to get a mirror on the second disk?
> X-RAID will automatically determine the best RAID to use, if you have a 2 bay NAS using X-RAID it will automatically use RAID1
So it might be a good idea to insert one of the old disks and one of the new and let them synchronize. Right?
Not yet.
What I suggest doing now is powering down, and inserting the first disk that you removed (that is the original disk 2). Put it back into slot 2, and leave slot 1 empty.
The power up the NAS. It should boot up, and give you a degraded volume. Verify that you access all your data. Then back the data up.
Note this is the same as @Marc_V's advice - it's just a bit more specific on the steps.
Good morning Stephen, good morning Marc (it´s 10:00 am in Germany :-),
I was too quick for your advice 😞
I put the old disk 1 in slot 1 and the new 6f TB disk in slot 2 and it seemed to synchronize for several hours.
I see the NAS in the explorer and can open the files - so everything seems to be fine. But RAIDar shows just the first disk as ok and the second (new one) as empty. (see picture RAIDar.jpg). Looking at the configuration page shows that disk 2 is no mirror of disk 1 (wrong RAID!?)
When I take off the (old disk 1) my explorer can find the NAS, I can see the folders ....but I can´t open the files and the admin page shows no volume.
Your proposal was: > Can you insert one of the disk without the 2 6Tb and see if it will boot normally? If it did boot normally I suggest doing a backup of your data then transfer it to the created volume from the 6TB drives
The first step was to save all my files, richt? - I already made a backup, before I changed the disks, so I got all my datas on another NTFS-disk .
Now, do you want me to put both new disks in and transfer the data by copying from the NTFS-disk to the NAS?
(I guess this is an workaround. Reading the manual it seems so easy to change the disks. I can´t see what I did wrong?)
Ok, I see the NAS and the shares in my explorer ... but I can´t copy files.
(Maybe some setings has changed when I updated the firmware . ....that sounds difficult 😞
The file-system of the NAS-formattet disks is an Linux-system, isn´t it?

Remove the 6 TB drive (disk 2) with the NAS running, and then make sure you can access the files/folders without it.
After that reinsert it (again with the NAS running). That should start another sync. When it completes you'll see a notification, and RAIDar should show a redundant volume again.
The difference to what I did is the running NAS. The manual (and what I found in internet ) said it doesn´t matter. But it matters!!!!
I always recommend swapping the disks with the NAS running. The NAS then detects the removal and insertion and doesn't have to figure things out.
There is a small downside - if you accidentally remove the wrong disk you need immediately reinsert it and wait for a resync to complete before you continue. But on the whole I think it works out better.
Anyway, wait for the notification in the web ui. Then you can try again with the second drive. After that sync is complete, re-confirm that you can access your files. If the volume size hasn't expanded to ~5.4 TiB, then reboot the NAS. That should trigger the expansion (which will require another sync on the expanded space).
now I got a warning message "Detected increasing uncorrectable errors (40) on disk 1 (ST3000DM001-9Y166,S1F0A95H) ....."
I guess this is the old disk. Will these erros infect the new disk?
With RAID-1 the sync process is copying everything on one disk to the other. So if the primary disk can't be read, then there could be some file system corruption on the other other drive.
One option is to let it complete, and then power down the NAS. Take out both disks, and try booting up with the other 3 TB drive in slot one. If that works, then hot-insert the second 6 TB. If that completes w/o errors, then just hot-swap the 3 TB drive with the other 6 TB (the one currently in slot 2). It will resync again of course.
My thinking behind letting the current sync complete is that the other 3 TB disk might also have errors.
Thank you for your help. I´ll try this after work.
Looking on RAIDar, everything seems fine. Going deeper I see only 3 TB as the disk-size
I guess it´s my fault, cause I skip the "factory default". I did so, cause I didn´t find in the manual how to do this just for the disks. I hesitate to do a factory default for the whole NAS.
Is there a shortcut or do I have to start the whole process from the beginning?
I don't know what "deeper" thing you are looking at. But the volume size will be 3 TB until you sync the second 6 TB disk. You should see the correct disk sizes on the volume tab.
I´m a little confused. You wrote: "That is the volume size, which is correct for 3 TB + 6 TB XRAID." But I have TWO 6 TB disks in my NAS. 3 TB was the size of the old disks, which I have changed. (Screenshot)
"Can you access those folders from explorer?" Yes it works fine and RAIDar shows that everything is ok
