I added an mSATA drive to my laptop and used it as an lvmcache for the LVM stored on my (spinning) hard drive. This LVM contains /home (as well as /var, /opt and /usr).
Upon booting (with kernel 4.9.8-1), it takes a while and I see the following:
(1 of 2) A start job is running for device dev-LVM-home.device (39sec / 1min 29sec)
(2 of 2) A stop job is running for LVM2 PV scan on device 8:35 (39sec / 1min 29sec)After that minute and a half, I see:
[ TIME ] Timed out waiting for device dev-LVM-home.device.
[ DEPEND ] Dependency failed for /home.
[ DEPEND ] Dependency failed for Local File Systems.
[ DEPEND ] Dependency failed for File System check on /dev/LVM/home.I then get the "you are in emergency mode" prompt. Pressing ctrl-d allows the laptop to boot up properly and /home (and its cache) is mounted correctly!
How do I fix this? How do I get it to correctly mount /home on boot?
In my /etc/mkinitcpio.conf, I have:
HOOKS="base systemd plymouth autodetect block sd-lvm2 filesystems keyboard fsck"UPDATE: The solution is to have /usr mounted as early as possible in /etc/fstab.

Hi, I might have the same problem. After a recent update my machine won't boot anymore. The root file system is on an LVM volume (which is on a software raid1) and I am getting a timeout waiting for that device.
I checked, that my fstab is correct (tried with UUID and dev path), the mkinitcpio hooks are fine so on. I can successfully use a live system to mount my file systems, so I think they are not corrupted.

Is there anything I can do here? Could it be an issue in my /etc/fstab? Might there be an option I need to add to /home to allow it to be mounted at boot time?

I figured out a solution!
Turns out I had /home mounted before /usr in /etc/fstab.
Moving /usr *before* /home (I put it right after /) fixed this issue.
