November 3, 20214 yr Hi I have an array with two 4TB data disks and a dead parity disk. I have two 8TB disks that I'd like to use for a new array and move the data from the old data disks to this. What is the best method? Kind regards Jacob

November 3, 20214 yr Author 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?
November 3, 20214 yr Just now, Dacobi said: backup of my backup Sorry, I usually phrase that question as Do you have another copy of anything important and irreplaceable. Do you mean your Unraid is a backup of files that already exist somewhere else?

November 3, 20214 yr Just now, Dacobi said: Ah yes I meant, I don't have a backup and not enough space to create one. Do you mean you DON'T have another copy of anything important and irreplaceable? If not that should be your first priority. Even if you had good parity, parity isn't a substitute for backup. You don't have to backup everything. You get to decide what is important and irreplaceable.

November 3, 20214 yr 2 minutes ago, Dacobi said: What about share and domain information? All of your configuration is on your flash drive. And user shares are simply the top level folders on array and pools. If those folders exist, the shares exist, and will use the corresponding .cfg from your flash.

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

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.

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
November 3, 20214 yr Linux command are fine if you are good with that. Many people are not. Do you know the paths to source and destination?

November 10, 20214 yr Author 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.
