my plan is to swap the disk against a bigger one, add it to the aufs pool and then copy the files from the old disk.
After testing a bit on my own, I'm still not able to unmount/swap a disk to replace it with a bigger one. The disks are pooled with aufs and snapraid does the parity stuff. I've stopped all plugin and services (e.g. smb) and deleted the snapraid configuration but under filesystem the unmount button is still grayed out. Or is it necessary to delete all shared folders too so no referencing is on the disk anymore? I don't know what to do next.
I'm grateful for any help or advice.
