systemd is like the service manager for your Centos and other modern Linux distributions (including Debian/Mint/Ubuntu) allows you to enable services, stop them, restart them, check their status and even reboot your system.
The key commands or arguments you will use with systemctl are the following:
list-units [PATTERN...] List loaded units
#mount the VCSA DVD
mount /dev/sr0 /mnt/cd
#alternatively you could mount the iso directly
mount -o loop vcsa.iso /your/mount/path
#for this purpose we are using the CLI installer on Linux
#no it's not going to be that easy you can't just run vcsa-deploy like that you need to use a template or configured .json file
Usage: vcsa-deploy [-h] [--version] [--supported-deploymen........
heartbeat is stopped for some reason
Anyway hnode2 was active and the services are running fine but I see heartbeat has been stopped somehow.
Here is the last log I see of heartbeat:
Sep 9 17:15:32 hnode2 heartbeat: : info: MSG stats: 9/1762471 ms age 0 [pid16738/MST_CONTROL]
