Can not mount an encrypted hard drive after Linux Mint crashed down

[better_solution]

Hi Guys,

I have problems booting in my system. After I pass the decryption of the hard drive successfully, I go only a black screen with BusyBox..... (initramfs).

If I boot my Mint 20.1 from USB drive, I can decrypt the sda3 but I can not mount it.

The only extra Installation on notebook was a Resilio Sync for online file synchroniying between two Linux Mint notebooks. I also adjusted a Timshift`with RSYNC. The recovery with Timeshift did not work out. I tried following without any success:

mint@mint:~$ sudo mount /dev/sda3 /luks-4d6dec4f-c7e4-4a6b-bdd3-16990202c42e
mount: /luks-4d6dec4f-c7e4-4a6b-bdd3-16990202c42e: mount point does not exist.

mint@mint:~$ sudo mount /dev/mapper/luks-4d6dec4f-c7e4-4a6b-bdd3-16990202c42e /luks-4d6dec4f-c7e4-4a6b-bdd3-16990202c42e
mount: /luks-4d6dec4f-c7e4-4a6b-bdd3-16990202c42e: mount point does not exist.

Now I would like to ask you kindly for your help. I only need to get access to my home folder where the container of the Resilio Sync is with all my personal data.

Here are some Information about my system:

I think the directory where you want to mount the partition needs to exist. So create a directory for sda3 somewhere and for the mapped crypt partition. Then mount those there. Like this:

Code: Select all

sudo mkdir /mnt/{sda3,crypt}
sudo mount /dev/sda3 /mnt/sda3
sudo mount /dev/mapper/luks-4d6dec4f-c7e4-4a6b-bdd3-16990202c42e /mnt/crypt

Thank you for your suggestion. Unfortunately it didn't worked out:

mint@mint:~$ sudo mkdir /mnt/{sda3,crypt}
mint@mint:~$ sudo mount /dev/sda3 /mnt/sda3
mount: /mnt/sda3: unknown filesystem type 'crypto_LUKS'.
mint@mint:~$ sudo mount /dev/mapper/luks-4d6dec4f-c7e4-4a6b-bdd3-16990202c42e /mnt/crypt
mount: /mnt/crypt: unknown filesystem type 'LVM2_member'.

Ah. I added code tags to terminal output of your first post to make it more readable. I thought sda3 was a regular partition that you were trying to mount but it's a LUKS+LVM partition. Don't bother trying to mount sda3. You want to mount the LVM volume vgmint-root.

Assuming you've already done cryptsetup open to unlock sda3 I guess you can just do:
sudo mount /dev/mapper/vgmint-root /mnt/crypt

It looks like my hard drive suffers under deep depression. He don't want to wake up:

mint@mint:~$ sudo mkdir /mnt/{sda3,crypt}
mint@mint:~$ sudo mount /dev/mapper/vgmint-root /mnt/crypt
