I have an existing BTRFS filesystem composed of one 500GB disk and I just bought a 2TB disk to increase the storage capacity of my home server and I want add the new disk to the existing filesystem. From what I read, it seems like no BTRFS setup can handle disk of different sizes without wasting the difference in size between the larger and the smaller disk, but I'm new to BTRFS and I might have missed something, so is there a setup that can allow me to combine two disks in a filesystem without wasting space ?
I run an ssh server on my machine and I restrict access to certain users to sftp only with internal-sftp & ChrootDirectory. What I need is a way to execute a script before chrooting users. Actually, the goal is to mount an encrypted filesystem on client connection and unmount it on close. Thx in advance.
