Hello everyone, for the last couple of days I've been receiving notifications from my monitoring systems about disk issues on one of my Zimbra Servers. The system is an old one I had with Zimbra Collaboration 8.6, and from there it has been upgraded to 8.7, 8.7.1 and 8.7.6 and finally to 8.7.10.
Finding the disk issue
I've started with the basics, what directory or file was eating my disk space without my knowledge? To do that, I've used the commands df and du, both always handy:
Checking that my disk was 100% fulldf -h
