I decided to add another HDD to my Snapraid + aufs setup. Before I make a mess of everything, I would like to review the procedure for this with you.
1) Install the drive (and labelled it 
) [done]
2) Creat phyisical and logical volumes [done]
3) Create a filesystem on the drive and mount it [done]
4) Under Snapraid -> Drives add the drive as a data drive and include the content file
5) Under pooling(aufs) -> Pools edit the existing pool and add a new branche (plus sign) with the new drive.
Is that about it? Am I missing anything? I haven't done 4 and 5 yet.
Best,
