  Virtual hosts are mounted over NFS:

  # df -h /var/www/vhosts/

  203.0.113.2:/vol/plesk_node_data/ 48G 83M 48G 1% /data.

Cause

Nginx configuration leftovers.

Resolution

1. Connect to the server via SSH

2. Delete the leftovers:

   # rm /etc/nginx/plesk.conf.d/vhosts/example.com.conf
   # rm -rf /var/www/vhosts/system/example.com/
   # rm /etc/nginx/plesk.conf.d/webmails/example.com_webmail.conf

3. Reconfigure the webserver:

   # plesk repair web -y

Note for servers with NFS: NFS partitions are currently not supported by Plesk. Please vote for such implementation in our UserVoice portal
