[SOLVED] crypthome wouldn't be mounted at bootup

Hi there!

Since my last system-update my /home-Partition wouldn't be mounted at normal boot time so I've to do an 'cryptsetup open UUID=xxxxx-xxxx-xxxx-xxx-xxx crypthome'.
When I leave the emergency-shell after typing in my password for /home the system boots normaly.

I don't know why I've to open my /home-Partition manually. Does anyone have an idea?

My setup is this:

- /etc/fstab

# /dev/mapper/cryptroot
UUID=371853a1-e151-4860-sdfsf-dgdgdfg456456	/         	ext4      	rw,relatime,data=ordered	0 1

# /dev/mapper/crypthome
UUID=b408e8e4-c932-4939-8a73-khlkg456456t	/home     	ext4      	rw,relatime,data=ordered	0 2

# /dev/nvme0n1p6
UUID=15FE-F049      	/boot     	vfat      	rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro	0 2

Please edit your post to use [ code ] [ /code ] tags as it makes input/output much easier to read.

How are you booting? How are you decrypting home?

Re: [SOLVED] crypthome wouldn't be mounted at bootup

What's in /etc/crypttab?

The content of my '/etc/crypttab' is  this:

# Configuration for encrypted block devices.
# See crypttab(5) for details.

# NOTE: Do not list your root (/) partition here, it must be set up
#       beforehand by the initramfs (/etc/mkinitcpio.conf).

# <name>       <device>                                     <password>              <options>
# home         UUID=b8ad5c18-f445-495d-9095-c9ec4f9d2f37    /etc/mypassword1
# data1        /dev/sda3                                    /etc/mypassword2
# data2        /dev/sda5                                    /etc/cryptfs.key
# swap         /dev/sdx4                                    /dev/urandom            swap,cipher=aes-cbc-essiv:sha256,size=256
# vol          /dev/sdb7                                    none

I think, my last update changed it but I'm not sure how I can see this!?

Re: [SOLVED] crypthome wouldn't be mounted at bootup

ok, so where are you expecting the container to be decrypted?

/etc/crypttab will not be overwritten automatically unless you haven't modified it at all. A .pacnew file would be created instead.

Re: [SOLVED] crypthome wouldn't be mounted at bootup

So probably you want to add home to crypttab so that it gets decrypted on boot? Right now you don't seem to have any mechanism for decrypting it?

If you configured crypttab before, pacman would not replace the file without telling you and likely wouldn't replace it at all. Look in /var/log/pacman.log for messages concerning .pacnew and/or .pacsave files. If you used something other than pacman to update, of course, that might affect what was done. pacmatic would ask you what to do, but I don't know about unofficial wrappers.

Edit: Should refresh before posting ....

Thanks for your fast reply and help. I found 'my problem'. I think after my last update I've overwritten my '/etc/crypttab'. Now I added this to my '/etc/crypttab' and it works fine :

 
home           UUID=7d10a58b-4cf3-44d3-8e0a-39c396c15657h                            cipher=aes-xts-plain64,size=512
