read_urandom: /dev/urandom: open failed: No such file or directory

Posted on in Categories last updated February 15, 2011

My CentOS Linux based server failed to boot with the following error:

read_urandom: /dev/urandom: open failed: No such file or directory

How do I fix this problem?

To fix this problem you need to upgrade mkinitrd package. To upgrade package use the Internet or install it using rpm command:
# yum update mkinitrd
Finally, build the image:
# mkinitrd -v -f /boot/initrd-2.6.18-194.el5.img 2.6.18-194.el5
Reboot the server:
# reboot
