Hello,

I have an elastic on a single server. I know, it's bad but I didn't pay so much attention to the Disk space.

The /var filesystem is full at 100%. I want to properly delete the oldest data, if I can with elastic but Elastic don't want to start.

When launching elastic in command lines, all of the Java exeption are saying : "Caused by: java.io.IOException: No space left on device"

What can I do ?

Thank you !

Welcome them to the community!

First, see if you can clean up root space on that volume. See [some docs](https://odzangba.wordpress.com/2010/02/20/how-to-free-reserved-space-on-ext4-partitions/) or google search.

Second, purge the OS and other logs at /var/logs, including any large elasticsearch or other logs - this may give you just enough space to start.

Else, you might have to move something you're not using to free space.

Thank you for your answer. I finally made some space and elasticsearch started normally.
