Swap partition errors on startup luks (wrong fs type, bad option, bad superblock)

[MeowMeow]

Using luks encryption, trying to get rid of this swap error on startup, everything starts up fine but there might be issues regarding hibernation, Im not sure so I wanted to fix it and also to get rid of the annoying message

(replaced actual strings with rootstring1…ect throughout for easier reading):

Startup Error:

mount: /openswap_keymount: wrong fs type, bad option, bad superblock on /dev/mapper/luks-rootstring1
Missing codepage or helper program or other error
        dmesg(1) may have more imformation after failed mount system call
Failed to open any keyfile
umount:cant umount openswap_keymount: Invalid argument
ERROR: resume:hibernation device '/dev/mapper/luks-swapstring1'

Cmdline in /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on iommu=pt quiet cryptdevice=UUID='rootstring1':luks-rootstring1 root=/dev/mapper/luks-rootstring1 apparmor=1 psi=1 security=apparmor resume=/dev/mapper/luks-swapstring1 udev.log_priority=3"

blkid lines for swap and root:

/dev/mapper/swapstring1: UUID="swapstring2" TYPE="swap"
/dev/mapper/rootstring1: UUID="rootstring2" BLOCK_SIZE="4096" TYPE="ext4"

full /etc/fstab/ config:

UUID=bootstring	/boot/efi	vfat	umask=0077	0	2
/dev/mapper/luks-swapstring1	swap	swap	defaults,noatime	0	0
UUID=rootstring2	/	ext4	defaults,noatime	0	1

Potentially relevant Errors in dmesg:

ext4: Unknown parameter 'subvol'

ucsi_ccg 0-0008: failed to get FW build information

failed to reset PPM!
PPM init failed (-110)
Adding 39843836k swap on /dev/mapper/luks-swapstring1.  Priority:-2 extents:1 across:39843836k SSFS

I feel like my fstab might be problematic, not sure if the UUID string is supposed to be different from the mapper string in blkid. Had a similar error originally after reinstalling manjaro and transferring my root partition that was:

mount: /openswap_keymount: no filesystem specified
Device /Dev/disk/byuuid/different-string
umount: can't unmount openswap_keymount:invalid argument

and I attempted to fix that error by correcting the grub, but the first error and configs below that, is where Im at now.

mount: /openswap_keymount: no filesystem specified

Have you tried forum search related to that?

/openswap_keymount: no filesystem type specified

Good news, I went back to step 1 and it turns out that the BIOS settings update did not do anything and it was still in RAID ON. After switching it again the live USB was able to detect the drives and I was able to boot normally. Thanks!

Mount: /openswap_keymount: no filesystem type specified

I was able to resolve the issue. Somehow my BIOS decided to change my SATA operation to RAID ON from AHCI. Due to this, the NVMe SSD wasn’t being read during load, which meant the path to the LUKS container wasn’t there. Props to this post for nudging me in that direction: LUKS encrypted drive is missing. “cryptsetup: lvm is not available” Hopefully this might help someone else encountering this issue in the future

Solution to access my encrypted Manjaro

You mount the decrypted partition, inside the encrypted container, on /mnt, but you generate a new /boot/grub/grub.cfg which is not inside the /mnt Plus you won’t get any different outcome unless you change the /etc/default/grub INSIDE /mnt and chroot into /mnt before you give the command to regenerate your grub config… Thus you need to in sequence: Open the encrypted container Mount the @ subvolume inside the container at /mnt chroot into /mnt Change /etc/default/grub from within…

None of those helped?

Im having this issue now after trying to fix that problem, that was the old issue which yes I did look up and did try to resolve and now Im getting this?
