Cloning data drive

flyinjoe13 · 27. März 2019

One of my data drives seems to be running a bit hot compared to my other drives. The other drives are in the 20's. The one i'm concerned about is hitting the low 40's. Unfortunately, it is the drive that has a lot of docker config files on it. So I have two questions.

1.) Can you clone an ext4 drive the way you can for an ntfs drive using cloning software?

2.) If I clone and swap the disk, will that wreak havoc on my docker containers? Or can I just mount and share the same folder structure and the dockers will see all of the files the containers need to run the same. Wasn't sure if anything is linked to a particular drive model name or just the drive location like 'dev/sda/'.

Thanks...

That isn't a problem.

Yes. omv-extras allows you to boot clonezilla and you could clone anything.

If you clone it and then remove the original drive, the system won't know that the drive was changed due to the way drives are mounted.

Well if it isn't a problem then I won't worry about it for now, but thanks for the info on what to do if it ever starts getting hotter.

Jetzt mitmachen!
