If this issue appears even though you have available disk space on the system:
* #df -h
We need to check available inodes on the server to see how many are available:
* #df -i
If we see inodes are 100%, or nearly 100% used on the filesystem then this indicates there must be a large number of files on the server and we need to find them using the below command. If the below commands stuck at a folder then it will be better to run it using that absolute path.
for i in /*; do echo $i; find $i |wc -l; done
After finding the folder with large number of files delete them and this will make inodes available to the file system.
This could be php session files located in ‘/var/lib/php/session’ folder containing millions of files. To get rid of them use the following:
# Shutdown apache --------------- service httpd stop # Rename php session directory --------------- mv /var/lib/php/session /var/lib/php/session.old # Recreate php session directory and set permissions --------------- mkdir /var/lib/php/session chmod 1777 /var/lib/php/session # Start Apache --------------- service httpd start # Delete session files --------------- cd /var/lib/php/session.old find |xargs rm The above command might take a day to delete the files depending upon the number of files in that folder.
