Manual Log Rotation Question

[beth]

Hi all,

According to the admin guide, to manually rotate the vertica.log file I should follow these steps:

1. Rename or archive the vertica.log file that is produced. For example:
$ mv vertica.log vertica.log.1
2. Send the HP Vertica process the USR1 signal. For example:
$ killall -USR1 vertica
or
$ ps -ef | grep -i vertica
$ kill -USR1 process-id

Is it really okay to kill all of the vertica processes on the node? Won't this bring down Vertica?

Hi Beth,

The USR1 signal is a user-defined signal. It’s not destructive and won’t kill a process the way that kill -9 would. Vertica traps the USR1 signal and interprets it as a request to open a new vertica.log file - solely for the purpose of log rotation.

Thanks, Sharon! That makes sense
