Constant Increasing of Disk Usage Size in Manager Host

[Elia Domenico]

Hi to everyone 😊

I have a cluster of three nodes, configured with Ubuntu 22.04 and MariaDB 11.4.
They are monitored by the Manager, which has Ubuntu 22.04 as well as the nodes and Galera Manager 1.9.1.
I use this cluster just for test purposes.

I have a increasing disk usage size in Manager: I've imported a db about three weeks ago in one node and then it was replicated in the other two nodes. No more actions and transactions happened from that, except from monitoring the nodes and the system by connecting to the manager from the web browser interface.

I've noticed that the disk usage size in the manager machine increases every day. I'm currently at 58.4% of disk usage.
The host has a disk with 40GB of size. I know that maybe it can sounds obvious, but I had 78% of free disk space two weeks ago.
How can I figure out what the problem is?

Thank you in advance 🙏

The stats now shows 66% of disk usage. I have only 33% of free disk space without doing anything in the manager and in the nodes.

Could anyone help me to figure out this? 🙏

Hi,

First thing is to identify what exact file(s) increase in size. Run ls -lSR | sort -k 5 -n few times on you database datadir and find out where the actual increase happen. If you could share you config and error log from problematic node, I can have a look if there is something problematic going on.
