Issue with inode filling up in `/dev/mapper` – Automatic Session Cleanup Not Working

I am encountering an issue with inode usage in the /dev/mapper/ directory, which frequently fills up and leads to “disk full” errors on my hosting. Here is a screenshot of the filesystem status:


To address this, I tried setting up a cron job to delete session files automatically:

sudo find /home/admin/tmp -type f -name 'sess_*' -exec rm -f {} +

However, this cron job doesn’t seem to work as expected, and I still run into the same issue.

Could anyone advise on how to:

  1. Resolve the inode filling problem effectively?
  2. Set up a reliable method to delete session files automatically every day?
