Red Hat

Hello all, perhaps this is an odd request, but I have the requirement none the less. Every time I mount a filesystem (at least an ext4 filesystem), I get a line indicating such in the syslog:

Oct 9 22:26:28 sulaco kernel: EXT4-fs (dm-1): mounted filesystem with ordered data mode. Opts:

I would like to not have these in the syslog. This is an encrypted filesystem that I would like to have no indication whatsoever that it exists. The OS lives on a regular non-encrypted volume. Obviously, messages in syslog indicating a mount of a Device Mapper (dm-1) filesystem will give away the existence of the encrypted volume.

Can someone advice on how to prevent these messages from being reported to syslog? Aside from shutting down syslog altogether, of course.

Thanks

Hi Lupin,

To do this you will have to edit the "/etc/syslog.conf" file, this determines where the system messages go.

In RedHat you will find the information if you use;

Code:

man syslog
man syslogd
man 5 syslog.conf
man 1 logger

If you would rather not modify syslog configuration for fear of losing other messages, since it's coming from the kernel you can use the loglevel kernel parameter at boot time (setting it to KERN_WARNING or KERN_ERR should do it). More Informaton on Kernel parameters.

A better question would be why you would want to not see this message, usually being able to tell when a particular filesystem was mounted is a good thing. Does doing a "grep -v" to filter out those messages not suffice?
