I have been given a task to creat a LUKS encrypted partition and then mount it, here are the steps I followed:
Create the partition for encryption:
sudo fdisk /dev/sda
Reboot
Format the partition with cryptsetup:
sudo cryptsetup luksFormat /dev/sda3
Open encrypted partition:
sudo cryptsetup luksOpen /dev/sda3 secret-disk
Add the following to /etc/crypttab:
secret-disk /dev/sda3
Make filesystem on partition:
sudo mkfs -t ext3 /dev/mapper/secret-disk
Make mount directory:
sudo mkdir /secret
Add the following to /etc/fstab:
/dev/mapper/secret-disk /secret ext4 defaults 1 2
Mount partition at /secret:
sudo mount /secret OR sudo mount -a
Reboot.
Problem: During reboot, the mount instruction in fstab returns the error : device not ready or not present. And I have to enter S to skip the mount so ubuntu can boot or M to recover it manually. I have checked this option but it does not solve mine. How do I get the encrypted partition to mount at /secret.

If the machine is uEFI, the ESP isn't encrypted (ESP=EFI system partition; again standards don't allow for encryption & mandate a FAT file-system for this). The ESP is part of the partition table for most modern systems. But boot partitions on both BIOS & uEFI can be encrypted.
How do I decrypt LUKS encrypted drive? ›
The decryption of a LUKS1 device is done in offline mode, i.e. it must not opened and mounted. If you want to decrypt the system drive, reboot into a USB live environment. Otherwise, use unmount followed by cryptsetup close dm-name . To start, identify the device_path using blkid or lsblk .
How do I open an encrypted partition? ›
My solution builds on the answer of Georg:
- Boot off a live-linux (so that you don't run into the duplicate volume group name)
- sudo cryptsetup luksOpen /dev/sdaX my_encrypted_volume.
- enter your passphrase when prompted.
- sudo vgscan should now pick up the contained volumes/groups.
- Open the bitlocker partition. $ sudo cryptsetup bitlkOpen /dev/sdb1 encrypt_shared. (It will ask for the bitlocker decryption password)
- Mount the disk. $ sudo mkdir /mnt/shared. $ sudo mount -t ntfs3 /dev/mapper/encrypt_shared /mnt/shared.
To access Recovery Console using Repair CD:
- Log into the Recovery Console CD. If the Device ID is editable, check the correct DeviceID from the PolicyServer.
- Click Recovery Console.
- In the left pane, click Decrypt Disk.
- Click Decrypt found on the bottom right. Wait until the decryption process completes.
The following steps will let you open the encrypted partition, assuming that the device file for the BitLocker partition is /dev/loop99.
- Create an empty directory for the BitLocker partition. mkdir /media/blpartition.
- Decrypt the partition. ...
- Create a mount point for the Windows partition. ...
- Mount the unencrypted partition.

The system partition (or system volume) is a primary partition that contains the boot loader, a piece of software responsible for booting the operating system. This partition holds the boot sector and is marked active.
We definitely don't need the /boot partition in every case.
In the general case, if we have a single operating system, there's no need to create the /boot partition as long as our hardware is recent (newer than 2000 or so). New machines don't have the old restrictions that required the creation of the /boot partition.

Can you remove LUKS encryption? ›
You CAN non-destructively remove the LUKS encryption from a device, without having to backup, reformat and restore. cryptsetup has supported this since version 1.5. 0, released in 2012. After succesful decryption of a LUKS device, the filesystem inside becomes available to the OS, and you can mount it directly.

LUKS encrypts entire block devices and is therefore suited for protecting the contents of mobile devices such as removable storage media or Notebook disk drives. The underlying contents of the encrypted block device are arbitrary, making it useful for encrypting swap devices.
