I followed this guide some time ago to set up my system (ubuntu 22.10) on an encrypted ZFS file system, and all worked fine. Part of the guide is to encrypt the swap partition.
Then, I upgraded the primary (swap, boot) drive to a larger one. I had cloned the disk over with clonezilla, which was also fine.
On reboot, I got an error as shown below:
It is pointing to the now removed hard drive swap partition.
I updated crypttab to point to the new hard drive's swap partition.
How do I remove/resolve the error?
FSTAB entry for swap:
/dev/mapper/swap none swap defaults 0 0
crypttab entry (reflecting the new SSD)
swap /dev/disk/by-id/nvme-nvme.c0a9-323235324536393636464333-43543430303050335053534438-00000001-part3 /dev/urandom swap,cipher=aes-xts-plain64,size=256,plain
I tried running ecryptfs-setup-swap with the below results:
$ sudo ecryptfs-setup-swap
WARNING: [/dev/dm-0] already appears to be encrypted, skipping.
WARNING: There were no usable swap devices to be encrypted. Exiting.
$ sudo cryptsetup status swap
