cant mount swapfile on boot (luks over lvm on 2 drive systemd)
I have luks over lvm on 2 drive system.
Here is my cmdline:
rd.luks.name=7ecbcf9c-734e-4b7d-90ff-b18e5cffdad4=linuxroot root=/dev/mapper/linuxroot rootfstype=btrfs rootflags=subvol=/@ rwHere is my fstab:

Re: cant mount swapfile on boot (luks over lvm on 2 drive systemd)
You've read and followed https://wiki.archlinux.org/title/Btrfs#Swap_file ?
Please post the complete fstab and don't copy it out of a pager as the latter truncates li>
It's not a block device, what's the actual output of "lsblk -f" and what would you expect to see beyond that?
Also how do you determine that "it doesn't work"?
To be clear, you cannot "mount" swap devices in the traditional sense to begin with.
Edit: ie. like entering it like a directory and look at files inside or so.

Don't use a swap file with btrfs, it's a horrible hack.

It's not a block device
Idk about btrfs swapfiles, but you won't typically see them in lsblk for that reason.

yeap, i managed to hibernate from tty, but is so strange. Its flicking why hibernating and it doest asks password when I entering system. Hibernation from active compositor session doesnt work anyway

Re: cant mount swapfile on boot (luks over lvm on 2 drive systemd)
i think that using logical volume will be better idea, i use lvm anyway. Its looks more stable and straightforward. I will try lately
