Dacobi Posted November 3, 2021 Share Posted November 3, 2021 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 Quote Link to comment
ChatNoir Posted November 3, 2021 Share Posted November 3, 2021 Your plan is to add the two 8TB, 1 parity and 1 data I guess ? Quote Link to comment

Dacobi Posted November 3, 2021 Author Share Posted November 3, 2021 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? Quote Link to comment

Do you mean your Unraid is a backup of files that already exist somewhere else? Quote Link to comment

Unassigned Devices plugin will let you mount the old disks outside the array. Quote Link to comment

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. Quote Link to comment

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. Quote Link to comment

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

But I'll make a backup of my domains before I proceed. Quote Link to comment
Dacobi Posted November 3, 2021 Author Share Posted November 3, 2021 To copy the data with unassigned device, do I just use a shell command? Quote Link to comment

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 Quote Link to comment
trurl Posted November 3, 2021 Share Posted November 3, 2021 Linux command are fine if you are good with that. Many people are not. Do you know the paths to source and destination? Quote Link to comment

Dacobi Posted November 10, 2021 Author Share Posted November 10, 2021 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. Quote Link to comment
