YaST Online Update (YOU) fails to give warning that /boot might be too small

This document (3817217) is provided subject to the disclaimer at the end of this document.


Novell SUSE Linux Enterprise Server 9 Service Pack 3


Updating the Linux kernel with YaST Online Update (YOU) succeeds without giving any error message, however on reboot the initial ramdisk (initrd) cannot be read or activated. The bootloader (where applicable) was updated successfully, though.


Check whether /boot is mounted and if/bootis large enough for the updated initrd file. In case it is too small, increase the size of the filesystem/bootresides on. Afterwards, run mkinitrd. On some systems, the boot loader (for example lilo orzipl,) has to get updated after creating a new initial ramdisk.

Additional Information

Unfortunately, rpm does not return an error code if a postinstall script fails. Subsequently, YaST2 cannot detect these kind of errors. It is recommended to use a /boot filesystem with a size of at least 128 MB to avoid this situation.
