Description:
Symptoms
Pre-check failing - Minimal disk space is available in SDDC Manager directory. Available disk space is 2 GB. Recommended disk space is 6.0 GB or more. Clean up unused files from the directory /
Purpose
This article outlines the steps to increase the partition containing /dev/sda4
Cause
audit.log grows to consume all free space on root partition /dev/sda4 and hence pre-check failsChecking the space utilization using "df -h" shows root partition usage root@afsc-vcf [ ~ ]# df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 7.9G 0 7.9G 0% /dev tmpfs 7.9G 20K 7.9G 1% /dev/shm tmpfs 7.9G 1.1M 7.9G 1% /run tmpfs 7.9G 0 7.9G 0% /sys/fs/cgroup /dev/sda4 28G 25G 1.6G 95% / tmpfs 7.9G 9.4M 7.9G 1% /tmp /dev/sda2 120M 27M 85M 24% /boot /dev/mapper/data_vg-vcf 181G 1.7G 170G 1% /opt/vmware/vcf /dev/mapper/data_vg-vmware 63G 2.3G 58G 4% /var/log/vmware /dev/mapper/data_vg-data 7.9G 160M 7.3G 3% /data /dev/mapper/lcmmount_vg-nfs--mount 503G 165G 313G 35% /nfs/vmware/vcf/nfs-mount tmpfs 1.6G 0 1.6G 0% /run/user/1000
Resolution
To clean up unwanted or large files Open an SSH session to the SDDC Manager applianceLogin as vcf and switch to root with "su -"Run the command to check for large files du -h / --max-depth 1Locate the large files and delete / clear if unwanted If messages log or audit.log or auth.log is over 1GB then follow the KB for Message log is not rotating on SDDC Manager If the above steps do not clear the space and you need to increase the partition size follow the below steps Note: For SDDC Manager 4.5 and 5.0, the below steps will not work.
