Configuring system properties

Advanced System Properties may be adjusted for system behavior.

1. On the Settings tab, navigate to System > Properties.
2. Edit the values that you want to change.
   1. Change the Automatic Shutdown Timeout value to modify the system process to forcefully terminate after the selected timeout period.

      By default, the system process waits indefinitely for transactions to close on Slicestor devices and Accesser devices when requested to stop. Select one of the following values from the Change Timeout drop-down menu.

      Attention: When you change this value, data being written may be lost.

      • None
      • 15 minutes
      • 30 minutes
      • 1 hour
      • 2 hours
      • 4 hours
      • 8 hours
      • 16 hours
   2. Change how long the system waits before reporting certain incidents.

      Device timers trigger when certain conditions are detected, when a corresponding incident is opened, or both.

      • Clear the default value to unlock the value slider.
      • Change the Processes Not Running value (Default: 3 minutes, Range: 3 - 60 minutes). This timer determines the "hysteresis count" for generating process down incidents. This is measured in polling cycles internally which roughly translates to minutes for a user (unless the polling cycle is modified).
      • Change the Slicestor Unresponsiveness value (Default: 30 minutes, Range: 3 - 60 minutes). This timer determines the "hysteresis count" for generating Slicestor device unresponsiveness incidents. This is measured in polling cycles internally which should roughly translate to minutes for a user (unless the polling cycle is modified).
      • Change the NTP Sync value (Default: 120 minutes, Range: 3 - 180 minutes). This timer determines the "hysteresis count" for generating NTP sync incidents. This threshold is for syncing with NTP server(s) configured in /etc/ntp.conf (NOT the event for when the local clock is not synced with the Manager clock). This is measured in polling cycles internally which should roughly translate to minutes for a user (unless the polling cycle is modified).
      • Change the Rebuilder Agent Hung value (Default: 1 hour, Range: 1 - 24 hours). This timer determines the amount of time the rebuilder agent waits before sending an event which opens an incident.
   3. Set the default destination rate limit for reallocation, which can be limited to minimize impact on I/O performance. (Default: 20 MB/s.
      1. Clear the check box to disable rate limiting by default.
      2. Change the default rate limit value.
   4. Set whether the Accesser Application enforces vault quotas. (Default: Disabled.)
      1. Select the check box to enable the Accesser Application to retrieve information from the Manager to enforce vault quotas.
         Note: This allows anonymous access to two APIs containing potentially sensitive information.
   5. Enable protection against cross-site request forgery attacks. (Default: Disabled.)

      For more information, see Enabling Cross Site Request Forgery protection.

   6. Select the preferred IP family.
      This setting prioritizes which family of IP address to use when establishing connections in the system. The preferred IP type is be attempted first, and if it fails, it falls back to the alternate IP type address. This preference only applies for devices setup with dual stack addresses. For single stack devices, IPv6 or IPv4, the preference has no effect and uses the one address available on the device.

      Note: IPv6 is available for ClevSO 3.10.1 and newer. Once the system has been upgraded, devices can be configured to use IPv6 stack in single or dual stack mode.

      1. IPv4
      2. IPv6
   7. Object Access: Select the preferred read access control for container or vault. (Default: Grant read access to all objects in the container or vault, and grant list access to the container or vault.)
      1. This option grants read access to all objects and grant list access to the container or vault.
      2. This option is more restricted, and grants ONLY list access to the container or vault.
   8. Set the Slicestor Storage Engine: The storage engine is set on newly added Slicestor devices once approved. Changing the storage engine has no impact on existing Slicestor devices. (Default: Zone)
      1. This option is the System Default (Zone).
      2. This option is Custom, and sets the Slicestor Storage Engine to File, Packed or Zone.
3. Determine which action you want to take:
   • Click Update to apply the changes.
   • Click Cancel to leave the Properties untouched.
