Completely removing references to an encrypted swap partition

Support
1

Hi,

Recently upgraded the drive in my laptop from 512GB to a terabyte. To clone the old drive I used clonezilla. I had to remove the swap partition as it was blocking me from expanding the data partition to fill the drive. Instead I created a swapfile on the encrypted data partition which is working well.

I commented out the references to the old swap UUID in crypttab and fstab. Also found two references in /etc/opencrypt.conf which I removed and reran mkinitcpio -P. Grepping the /etc directory recursively I can find no further references to the UUID. I also checked /etc/default/grub as mentioned in other posts. Yet an error still persists on boot and shutdown which flashes briefly on the screen. It does not prevent the system starting but would like to remove the error.

Device /dev/disk/by-uuid/<uuid of deleted swap> does not exist or access denied

Can anyone help me find what I’ve missed to completely stop the system looking for this now removed partition?

# MODULES
# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES=(piix ide_disk reiserfs)
MODULES=""

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way.  This is useful for config files.

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
##   This setup specifies all modules in the MODULES setting above.
##   No raid, lvm2, or encrypted root is needed.
#    HOOKS=(base)
#
##   This setup will autodetect all modules for your system and should
##   work as a sane default
#    HOOKS=(base udev autodetect block filesystems)
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS=(base udev block filesystems)
#
##   This setup assembles a pata mdadm array with an encrypted root FS.
##   Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
#    HOOKS=(base udev block mdadm encrypt filesystems)
#
##   This setup loads an lvm2 volume group on a usb device.
#    HOOKS=(base udev block lvm2 filesystems)
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr, fsck and shutdown hooks.

I have commented out the places where the old swap partition was (9bd2fcd4-1711-415f-a7e1-4a7c712d7b61). Grepping the rest of /etc for that uuid i come up empty handed.

I think the following should be removed from your /etc/default/grub file:

In your /etc/mkinitcpio.conf change

exactly into

HOOKS=(base udev autodetect modconf block keyboard keymap encrypt openswap filesystems)

Afterwards execute

sudo update grub
sudo mkinitcpio -P

and reboot.

Thank you for your help. That almost solved it. I tried your solution but the error was still there. So I edited /etc/mkinitcpio.conf again and also removed the openswap reference.

So now my HOOKS line looks like

HOOKS=(base udev autodetect modconf block keyboard keymap encrypt filesystems)

Will mark the post solved. Thanks again.

Now I just need to work out how to remove hibernate from the shutdown menu.

To remove hibernate from shutdown menu you need to edit /etc/systemd/sleep.conf

AllowHibernation=no
AllowHybridSleep=no
AllowSuspendThenHibernate=no

and /etc/systemd/logind.conf

HibernateKeyIgnoreInhibited=no
