[SOLVED] Encrypted swap

[wynnmc]

I can't get my encrypted swap partition to mount. The relevant lines in /etc/conf.d/dmcrypt are

Code: Select all

swap=swap
source=/dev/nvme0n1p2

and the line in /etc/fstab is

Code: Select all

/dev/nvme0n1p2          none            swap              sw              0       0

when that didn't work, I changed it to the suggestion in the fstab as supplied

Code: Select all

LABEL=swap		none		swap		  sw		  0	  0

which doesn't work either. The lines shown by lsblk are

Code: Select all

├─nvme0n1p2                                                                             
│ └─swap    swap        1           f040ab1e-12c8-4552-9175-b19a871ad3a3 

. I have tried /dev/swap...

I rebooted and noticed that dmcrypt referred to the encrypted swap file as

Code: Select all

/dev/mapper/swap

-- because it wasn't LUKS, it didn't occur to me that it needed the "mapper". I have now changed it in /etc/fstab and it works...
