Protect the ESX Host so that the Root File System does not fill up
Make sure that each of the following directories is mounted on a separate partition:
/home
/var
/tmp
/log
Remediation
- Log into the service console via ssh
- Run the command “df -k” this will show the current partition structure. You should have separate entries for each of the above directories.
- If you do not have separate directories then you will need to create new mount points for each of the directories and create new partitions on the disk.
- If you do not have enough disk space then you will need to make a decision on how practical it is for you to make the necessary changes in order to comply with this rule.
- Alternative approaches to not doing this would be to create a cronjob that monitors disk space and archives off log files and or deletes unwanted files to avoid the situation of the root partition filling up.
NOTE: Altering disk partitions is a skilled job do not attempt this if you are unsure of what you are doing and always make a backup first.
“Datastore Partitioning,” an appendix of the Installation
and Upgrade Guide, covers disk partitions in more detail.
