I could restore it so only 3 drives are used and have up to 8TB effectiver storage with RAID 5 ?
Yes to this.
but i just want to make sure i dont loose all the config
Normally you would do this with a factory default - then reconfigure the NAS and restore your data.
It is possible to shrink the array using ssh though. The gist is that you first shrink the file system down to 8 TB, and then you change the mdadm RAID mode.
Sandshark has experimented with this, and posted some results here:
It's not something I've tried, but perhaps he would be willing to post the needed commands for your situation.
That is, to reduce a 4x4TB degraded volume with a single RAID-5 group to 3x4TB.
I've seen other ReadyNAS with that issue. Sometimes, replacing just the SATA backplane is a fix, other times the whole motherboard has to be replaced. Since parts are unavailable, though, that's not something most can do.
Anyone with a new in-the-box ReadyNAS is likely asking a lot for it since they've been unavailable for quite some time now. But there is a good possibility that if you actually inquired, you'd find that vendor really doesn't have one. So, you are looking at a used NAS. A 214 or better would be a good choice. A Pro or Ultra 6 converted to OS6 would also work for you, and they tend to be more available and affordable (but I don't know about your country). They would also be a bit faster than a 104 except for USB, which is limited to USB2 on those models.
If you decide to use just three drives, the easiest way is to factory default and start over. Even if you want to upgrade to larger drives, you first have to reduce the RAID to 3 drives or do without redundancy. Personally, I'd consider that just a temporary fix. Without knowing the cause, there is no telling if another bay will fail.
