evms_activate is not available on boot

Monday 2 July, 2012



You have (or had) encrypted partitions in your system and are now getting the following error on boot;

evms_activate is not available

WARNING: This is only applicable if you have already checked your /etc/fstab and /etc/crypttab and made sure there are no errors etc in those.


You need to rebuild your initramfs to fix/remove the pointers to the encrypted partitions. The following command will do this;

update-initramfs -u -k all

One method of doing this is to boot from a Linux boot cd, mount your FS, chroot into your install and rebuild the initramfs.

Step-by-Step fix

  • Boot from your favourite distros Live CD. (e.g. Ubuntu 64bit desktop)
  • Open a terminal and run the following commands, replacing sda1 with your root partition (if your /boot is on a separate partition, then you will need to mount that also)
sudo su
mkdir /mnt/fix
mount /dev/sda1 /mnt/fix
mount -t proc none /mnt/fix/proc
mount -o bind /sys /mnt/fix/sys
mount -o bind /dev /mnt/fix/dev
chroot /mnt/fix /bin/bash
update-initramfs -u -k all
  • Reboot the system and cross your fingers!
