Log file for startup processes

Ronald Cogen — Fri, 13 Feb 2004 03:21:19 GMT

Hello out there,

Where is the file for the start-up processes (rc..) which also includes the messages for volume mounts (using LVM)?

Hi,

are you looking for /etc/rc.log?

most of the log stuff is located in /var/log...

try looking in:

/var/log/messages
/var/log/boot.log
/var/log/dmesg

You might try /etc/inittab
You can put your own startup scripts in /etc/rc.d/rc.local

RedHat has them there.

Some distributions may put them in a different place.

Thanks for the quick response.

Yes, I was looking rc.log, but discovered that it is only included on HP systems, which is not the case here (surprise!). The logs in /var/log didn't seem to give me the information I wanted. Someone just told me I should be content with dmesg. The problem was that a volume didn't get dismaounted at shutdown because the mountpoint of the volume, /opt/ was getting written to. I thought I could find out which process it was by looking at the mount process log.

agree with Jeffrey, there is also a command dmesg.

Hi,

You may replace for example rc"1-6".d in /etc/inittab with your own scripts which then calls:
rc"1-6".d | tee /tmp/rc1d.log
You would have to make a copy of tee to /sbin

does that make sense to anyone?

Hello Roland,

on my system there is a file called /var/log/boot.omsg which contains all messages from the last boot/shutdown cycle. If there is anything usefull displayed at shutdown you should be able to find it there. One thing you might try is to include an lsof in the shutdown script dismounting the disks to get information on the process hogging the disk.

Greetings, Martin
