drbd_selector.sh

January 14, 2009 in , , , , , with 140 Comments

Here is a quick bash code snippet. It allows the execution of code/scripts on a server with a Primary drbd array.

It does not take into account that there can be more than one array, or that split-brain scenario exist, or that the script might be not-executable, or …

I’m really posting that because I get to use it quite often and always forget ‘how I did it last time’… the search function on this blog is kinda nice ;-).

if [ $(grep st:Primary /proc/drbd | wc -l) = 1 ] ;
then $@ ;
fi
