I started having issues with my server of 3 months few days.
Firstly, I noticed that my WHM backup isn't running. After searching online, I discovered the CPU usage is lower than the WHM threshold, which I increased accordingly. After forcing a backup, the backup ran successfully.
Today, I discovered my sites are very slow, and when I looked into the WHM process manager, I saw that Mysql is eating up too many CPU. Therefore, I restarted the Mysql service.
The sites ran well for 1 hour, only for the issue to arise again, now I tried accessing WHM which failed with an error and all sites stopped opening. I searched for the error seen and saw the issue is with inodes.
I decided to reboot the server via my OVH control panel before taking further steps. And it's been hours now after reboot and I cannot connect to the server via SSH and all sites are down.
Although I can PING my IP, but nothing else works. I've created a support ticket and no response yet.
A community help will be highly appreciated.
Note: I'm new to server management.
