Encrypted Btrfs storage setup and maintenance guide

Initial setup with LUKS/dm-crypt

This exemplary initial setup uses two devices /dev/sdb and /dev/sdc but can be applied to any amount of devices by following the steps with additional devices.

Create keyfile:

dd bs=64 count=1 if=/dev/urandom of=/etc/cryptkey iflag=fullblock
chmod 600 /etc/cryptkey

Collection Type Guidence

When to use what

• Use Arrays if you know the element types and have a fixed length and/or known-up-front collection size that will not change.
• Use ArrayList if you have an unkown collection size with either unknown or mixed type elements.
• Use a Generic List when know the type of the elements but not the size of the collection.
• Use a HashTable if you are going to do key based lookups on a collection and don't know the object type of the elements.
• Use a Dictionary<TKey, TValue> you are going to do key based lookups on a collection and you know the type of the elements.
• Use a HashSet when you know the type of elements and just want unique values and quick lookups and assignmnets.
