Comment 3 for bug 1420256

Tried to boot a node directly from a disk (w/o chain loader). The error is the same which means that we really had a problem during provisioning. Fuel Agent logs are clear and does not contain any errors. Tried to run the provision script manually and then just after it finished, I tried to mount /, /boot, /proc, /dev, /sys file systems and run grub-install manually against all the node hard drives and then rebooted. The node managed to boot successfully with the error "diskfilter writes are not supported" which appeared just after grub menu (hidden) and before splash. Took a look at the /var/log/remote/node-N.domain.tld/bootstrap/messages.log file and it looks like the issue appears when sysrq message (unconditional reboot) is sent to a failed node while it is being provisioned.
