Unable to boot when using crypttab and encrypted home

Boot error: A start job is running for dev-mapper-home.device (11min 01s / no limit)

It just hangs here forever. Never makes it past. I'm guessing the "no limit" is one problem. The other being that I can't boot.

I have my home partition encrypted with dm-crypt. Root and boot partitions are not. The home partition is accessible when I do it manually with the commands:

$ cryptsetup open /dev/sda7 home
$ mount /dev/mapper/home /home

Unfortunately, trying to use crypttab and fstab are not working.

My crypttab entry:

home    /dev/sda7    none    plain

My fstab entry:

/dev/mapper/home    /home    ext4    defaults    0 0

UPDATE
Tried switching to using LUKS instead of plain. After reformating the partition, and updating the crypttab to state luks instead of plain, gets further, but still not correct. It asks for a password and then gives error about invalid option for systemd-cryptsetup. This happens no matter what password I put in, correct or not.

Re: Unable to boot when using crypttab and encrypted home

If you have listed your code correctly, then the problem may be this:

mount /dev/mapper/home /home

When installing, you are supposed to use /mnt:

mount /dev/mapper/home /mnt/home

This is so when you use genfstab, it doesn't get confused with the mounted ISO. Have another look at /etc/fstab.

Edit: check you have added "encrypt" to mkinitcpio, and check that your bootloader is correctly configured for encryption.

Re: Unable to boot when using crypttab and encrypted home

I already had the system installed. I was reformatting the /home partition to be encrypted. So I wasn't using genfstab. But I did change my /dev/sdaX to /dev/mapper/home when I reformatted it in fstab.

Re: Unable to boot when using crypttab and encrypted home

Can it be a keymap problem?
Did you use special cipher or hash options when using cryptsetup luksFormat?
