Thanks! The settings was already "All" but I set it to "Disk1" and then back to "All" and now it works. (Edit) And yes, I went from 3x 4TB drives to 2x 8TB drives.

I have an unRAID server with 2x 8TB drives and no cache drive. Lately one of my shares have been saying "No space left on device" when I try to write to it. I can still read from it and my other shares on the same array have no problem. I've recently lost a disk but the problem was still there after I rebuild the array. tower-diagnostics-20220212-1916.zip

Thanks for all your answers, I've been running Linux for many years but I'm not very familiar with unRAID or RAID in general.

I've shutdown the array, removed the disks and booted with the new disks. But the unRAID is still expecting to find the old disks. Should I use the New Config tool to create a new array config? Will this preserve share/domain information? I've made a backup of important data.

Well the array would be /mnt/disk# Don't know where unassigned device will mount?

Well I was thinking something like cp -rf etc etc What I meant was if there was a more "official" way to move data? Last time I used a commander it was called Norton

To copy the data with unassigned device, do I just use a shell command?

It's not life or death data, I just only had the means to buy new disks to replace the old and failing once. But I'll make a backup of my domains before I proceed.

Thanks, then I'll shutdown the old array, create a new one and copy the data from the old disks with unassigned device

What about share and domain information?

Ah yes I meant, I don't have a backup and not enough space to create one.

Could I shutdown the current array, then create a new array with the two 8TB disks and attach the old data disks and copy that data one by one to the new array?

That's the problem, I don't have enough space for a backup of my backup.

Well not add, I'd like an array with only the two 8TB drives and then move the data from the old 4TB drives to the new array

Yes
