The system is an AWS Instance based on a community CentOS 6.4 AMI snapshot.
The vdisk is as follows as shown below [1] The root LVM contains /var/log/
I have attached another block device with ext4 FS.
I copied the files from /var/log to this device (mounted on /mnt) and then changed /etc/fstab to mount this device on /var/log on boot.
However, I do not see anything being logged in /var/log/messages. To test the logging, I used the 'logger' command to log some string; nothing appears in /var/log/messages.
'service rsyslog status' reports the daemon is running.
When I stop rsyslog, umount the /var/log device and then restart rsyslog, I can see that logs are being recorded in /var/log/messages. Using the 'logger' command I can see messages written in /var/log/messages.
man pages of ryslog.conf and rsyslogd show nothing related to logs being on a separate device
Any pointers to fix the problem would be much appreciated.
