https://bbs.archlinux.org – Since some recent update one of my LUKS-encrypted volumes is not being mounted correctly.I used to have this .mount file as the volume actually is a multi-device btrfs volume:[Unit] Description=/mnt/archive Wants=cryptsetup.target After=cryptsetup.target [Mount] What=/dev/mapper/archive1 Where=/mnt/archive Type=btrfs Options=defaults,noatime,nodiratimeThe error I get when I try to manually start this service is:systemd[1]: Expecting device dev-mapper-archive1.device... thor systemd[1]: Job dev-mapper-archive1.device/start timed out. thor systemd[1]: Timed out waiting for device dev-mapper-arc (HowTos)

I recently switched to systemd and have some issues with a multi-device (raid1) btrfs volume.My fstab contains this line for the volume:/dev/mapper/archive1 /mnt/archive btrfs device=/dev/mapper/archive1,device=/dev/mapper/archive2,device=/dev/mapper/archive3,device=/dev/mapper/archive4,defaults,noatime,nodiratime 0 0As you can see, the volume consits of four LUKS mapper devices, which must all be

I have an encrypted loopback volume. I need to mount and umount manually the volume so I use cryptsetup luksOpen and cryptsetup luksClose .

However, When I invoke this command it pops up the /dev/mapper device under all the sessions under gnome/xfce/kde/unity ...

And then it let the user to mount (with password), expulse and unmount the volume.

It's quite annoying in a multi user server (you ar

systemd seems to stuck on mounting an encrypted volume, when I set the init to /usr/sbin/systemd in grub.cfg,

I have one line in /etc/crypttab

secure /dev/sda8 /etc/cb.key

That works with original init program, but when I switched to systemd, it stuck at

[ OK ] Reached target Encrypted Volume

And it got the right device name, right mapper name, but just won't go on.

I have an encrypted loopback volume.

I created an encrypted container via

#!/bin/bash dd if=/dev/zero of=$1 bs=1 count=0 seek=1G MAPPER=$(mktemp -up /dev/mapper) LOOPDEV=$(losetup --find --show dm1) cryptsetup luksFormat $LOOPDEV cryptsetup luksOpen $LOOPDEV $(basename $MAPPER) mkfs.ext3 $MAPPER cryptsetup luksClose $MAPPER losetup -d $LOOPDEV

i.e. a file e.g.

Thanks for the prompt response. Ok, the key to my partition is a file based key, which is GPG encrypted. In order to use the key, I need to enter the password to GPG to decrypt the key, so that it can be used by cryptsetup. As far as I know there is no way to get crypttab working in this scenario.

At first I had a problem in which the initramfs didn't map LVM partitions to /dev/vg0/lv, only /dev/mapper/vg0-lv. I changed /dev/vg0/root to /dev/mapper/vg0-root in bootloader configuration as a hacky workaround.Getting closer to a working system, systemd failed boot because my fstab entries are uuids, and for some reason, my LVM volumes aren't showing up in /dev/disk/by-*.

With 11.2 I let it do a default install using LVM+encrypted and all went smoothly. I haven't used LVM before. I've done normal encrypt -cryptsetup LUKS- before and could always boot a rescueCD, run appropriate commands and mount chosen device to do backups or whatever.
