Hi Mark, thanks for your help.. but /var/log/messages does'nt bring the boot log fails!

I Have a few boot.log files at /var/log but all empty (0 bytes)

at /etc/syslog.conf the line which refers to system boot log appears to be ok... see

# Save boot messages also to boot.log
local7.* /var/log/boot.log

Any Idea?

Cleiton

Have you read through messages from the boot? Or how 'bout dmesg?

You should be able to use ctrl-s to stop the flow of text, then use page
up/down to view the actual messages; when done, ctrl-q (IIRC) will
resume output to the terminal.

This was broken in rhel5. I think all flavors. Just google 'rhel5
boot.log empty'. It is fixed in rhel6 with the addition of plymouth.

>From the rhel5.3 releasenotes:

Boot-time logging to /var/log/boot.log is not available in Red Hat
Enterprise Linux 5.3

How are you able to see the console if you don't have physical access?
If you're using an IP KVM, IPMI, or serial console, ctrl-s from your own
terminal should still work.

This was taken out of RHEL in 5 and was to be replaced.
However, I've not seen where, though I've not looked at 6 yet
