rsync cache drive to new drive; will DOCKER work?

Featured Replies

I just want to make sure this will work before I screw up my docker.

 

I want to upgrade my cache drive from a 3TB drive to a 5TB drive.  I have formatted and mounted the new drive using "Unassigned Devices."  I ran the following:

# rsync -va /mnt/cache/ /mnt/disks/ud/

Where ud is the name of the mount.

It's running now. 

 

Firstly, did I use the correct rsync commands? 

 

Secondly, if I stop the array, remove the old cache drive, then assign the new cache drive in its place, will everything work as before with docker?  I really don't want to have to setup everything in docker again!

 

Thanks,

craigr

The answer is that it works just fine.  Remember to turn off docker while copying, then turn it back on after the swap.

add VM's if they are running too.

And just stopping the individual dockers and VMs isn't enough. You must disable dockers and VMs in Settings.
