Need to make a new config, but..

[Hanfufu]

As the title suggest, i think i need to make a new config, on my new unraid install.

I am btw completely new to the linux/unraid stuff, as I have used WS the last 15 years.

 

I just shucked a WD drive, and was not aware of the fact that it would show up with a different UUID.

 

So I just need to get that disk replaced and nothing Else.

I dont yet have parity drives, as I først want to migrate all my data to the array, and then add 2x18TB parity disks.

 

But I am scared sh1tless tbh, that something will go wrong with my dockers/vms in the process. I finally got them all setup and running.

I have 1 1TB SSD as a cache pool, with dockers and vms on. Also, one vm is running off a second cache pool called vms, as I only need to run that for a few more months, and then the disk can be removed afterwards.

 

So my question: Will making a new config, screw up my VMs and Dockers - assuming that I select the preserve option for all disks, and only remove the external "version" of the drive, and add the drive under the new UUID?

No, but there could be issues with the shucked drive, if the size is not the same as it was and/or it's hardware encrypted by the enclosure, some WD USB drives are.

Thank you for that answer! I didnt expect the enctyption thing tbh, but when i attached it via sata, it did report it as 12TB.

 

So the only way to know, would be to make a new config with the disk on sata, remove the old UUID, add the new and start the array. Then if the disk has unsupported format, that would indicate that the disk is encrypted, and if it mounts it and I can see files on it, it would show that it was not encrypted?

 

Or just leave it as USB, is always an option also.

USB connections not recommended in the array or pools for multiple reasons, such as the problem you have already encountered and others already mentioned.

 

Also, USB can disconnect, which will make the disk out-of-sync and require rebuild. Could be a frequent occurrence.

Yeah I kinda saw something about that, and I am also experiencing slow downs when copying to the array, though not to that disk, but im thinking the USB disk could be casino some problems.

 

I just really wanted to keep it as USB, as it is not a NAS disk like my others, and it would need to be in a case with 11 other disks. In thinking the vibrations are gonna kill it in the long run.

 

But I guess there is no way around trying new config then.

Not really that important for Unraid since the disks can spindown.

[Hanfufu]

Thanks alot for the answer!

 

Btw is it best to do it like this:

 

Stop array.

Make new config (preserve all)

Remove disk.

Start array.

Shut down server.

Switch the disk to sata.

Start the server.

Then stop the array

Add the new UUID.

 

And if its encrypted and unreadable, do it again to add it as USB, and then use unbalance plugin to move the data off the disk and then afterwards add it as internal?

Why not just

Well you do make a point!

That way it would only cost me time because it needs to copy 4.5TB of data off of it, and not have the risk of something going wrong, either the disk being encrypted/config screws up.

 

Will unraid redistribute the files automatically, when i add the disk as empty afterwards?

 

And ty so much for your time!

No. Not really necessary but unBalance has that ability.
