When you want to recover a problem that is disk capacity is full.
In this case, when the disk capacity becomes full and the system is down, record about immediate actions.
When the disk capacity is full and the system goes down
When the disk capacity becomes full, the system may go down. If this is a production environment it is highly urgent so I’d like to recover quickly.
This time I will describe the response of immediate recovery rather than solving the fundamental problem.
Check which dir is full
First of all, we should check which directory is using capacity with
du -sh command.
Check the files in the target directory
Check the file in the target directory and check the contents if there is error.log etc. If there is a lot of logs expired with some error, restart the system once, save the target log to another server and delete it from the target server. And then, lighten the disk capacity as much as possible.
Precautions for system down
- Install log rotation
- Configure disk space alerts
For AWS, you can set alert of disk capacity in CloudWatch with custom setting. The following article is helpful.
If you run for the first time, it may be that some perl modules are missing and it may not work, so let’s check the error log for proper installation.
install Crypt :: SSLeay test may not work,
but it seems that you can set TEST to NO. ←
I do not think so well. lol
