I configured "Hard disk quota" limit in Service template, but in the Customer Control Panel I see that the quota is always unlimited (not supported by filesystem configuration).
How should I propagate changes if I changed OS configuration?
Check if quota is activated:
# /usr/local/psa/admin/bin/usermng --isquotable
If it returns '0', it means that quota is supported on the server. "1" hard disk quota is not supported due to configuration of server file system.
If not use #768 article to activate disk quota.
To propagate changes in the node's operating system to Plesk Automation click the "Refresh" button:
Infrastructure > Service Nodes > select the node > Summary tab > Refresh
