Root filesystem 100% occupied

Introduction

On the smaller provisioned TVC systems the root filesystem runs out of free space. The scheduled process of removing the logfiles is somewhere hidden in TruView Java code. On systems with very small disks this process kicks in too late.

 

Solution

Create a cronjob that deletes Cassandra logfiles from the /tmp directory

Logon to TVC console and run the following commands:

# sudo -i
# crontab -e

And append the following line

30 15 */2 * * find /tmp -maxdepth 1 -name '????????-????-????-????-????????????' | xargs rm -rf

This command deletes the Cassandra logifles every 2 days at half past three in the afternoon. Be aware that during an update of TruView the crontab is replaced and as a result of this the added cronjob will be removed.
