I've recently installed munin on my VMware client server and saw that the Disk usage shows about 80-90%. Everything else (cpu load, ram, etc.) seems to be running fine. I have only two virtual hosts on my server with 1000 users/day in total, so I don't think that's too much.
Here is the graph for the disk usage.
Server info: Debian Lenny, CPU 510Mhz, RAM 512MB
Is it bad? What could possibly cause this?
Thank you for any suggestions.
