Disk Space
Hi, I've got a question on free disk space. I'm currently running CentOS 5.5 on in Xenserver virtual environment. We've had an issue with disk space. My question is as follows: -
from a ssh connection i run df -h this gives the value of 90% used leaving me with 9GB. If I use system monitor via a VNC connection the free disk space value is 20GB free on the same volume. Which one is correct? I do use SNMP to monitor the same volume and should alert me when < 10% is free I know this works as I set the alert threshold to < 90% I get an alert. I'm some what confused. atb Alex |
"df" counts whole filesystem blocks, which leads to a higher value of "used space" than the sum of all file sizes. Depending on the method this "system monitor" uses, this could explain the difference, although a difference of 10GB on a ~100GB partition seems a little high.
What does the following command say (can take some time because it counts all filesizes): Code:
du -hs |
I've resolved this issue some strange happened to the VNC screen so I've restarted the VNC service and it appears to be in synch with the command line output.
