nice, ionice parameters on Auto FTP Backup page do not take effect for KVM/XenHMV slave nodes

Symptoms 

Ionice Priority, Ionice Class, Nice parameters set up at SolusVM > Nodes > Node > Auto FTP backup are not applied when cron task for AutoFTP Backup is running on KVM/Xen slave nodes. 

Cause

Known SolusVM issue with ID #SVM-1093

Resolution

As a workaround

1. Connect to the corresponding Slave node via SSH
2. Create a backup of /etc/cron.d/solusvm_ftp file

   # cp -a /etc/cron.d/solusvm_ftp /root/solusvm_ftp

3. Update the cron task: 

   CONFIG_TEXT: 0 0 * * * root /usr/bin/php /usr/local/solusvm/includes/autoftpbackup.php >/dev/null 2>&1 

   After

   CONFIG_TEXT: 0 0 * * * root nice -n <nice> ionice -c <ionice_class> -n <ionice_priority> /usr/bin/php /usr/local/solusvm/includes/autoftpbackup.php >/dev/null 2>&1 

   Set values for Ionice Priority, Ionice Class, Nice as required.
