SDDC Manager precheck fails on vCenter with:
"Verifies the vm <vcsa shortname> running in vcenter <fqdn> has at least 30GB free space on path / High: Do not perform upgrade without addressing this issue."
The vCenter root partition is below the required 30GB:
The journal entry is filling up more than the allowable space.
To confirm that the journal logs are taking up the space:
The journal log subdirectory is a long numeric string. The directories may be GBs in size.
Change the max size of journal logs to 1000M and reboot the vCenter.
Edit this file:
/etc/systemd/journald.conf
Find this line:
SystemMaxUse=1000M
(Note: If this line is commented out with #, please remove the # and then add the value)
Reboot the vCenter:reboot -f
