Settings
Settings holds the node’s fleet registration, its email notifications, its location, its RAM cache and the power buttons. On a fresh install, Fleet shows the registration made during setup, Notifications and Location are not configured yet, RAM cache is limited to 1.5 GiB, and Power lets you reboot or shut down the node.
The Fleet card shows the fleet account the node is registered with and whether it is connected. Select Edit to register it with a fleet account again, or Register if it is not registered yet.
Status turns the connection to the fleet on or off. On univrs.cloud it cannot be turned off, because the fleet provides the node’s DNS record and certificate. On your own domain it can.
If the card says Registration expired, please re-register., select Edit and register again.
Notifications
Section titled “Notifications”The node emails you about problems with its storage pool and drives, and about what changed when updates are installed. For that it needs an SMTP server to send through. Select Edit on the Notifications card.
- Encryption: None/StartTLS for servers that start encryption on the connection, usually on port 587, or SSL for servers that expect it from the start, usually on port 465.
- SMTP server and Port: the address and port of the mail server.
- SMTP username and SMTP password: the account the node signs in to the mail server with. Leave both empty if the server does not ask for one.
- Sender email address: the address the emails come from.
- Recipients: the addresses the emails go to. Separate addresses with a comma or a space.
Location
Section titled “Location”The location sets where the weather on the Dashboard is for. Select Edit on the Location card, then enter the latitude and longitude, or select Get location to use your browser’s location.
Once a location is set, the Dashboard shows the current weather there, updated every hour.
Select it to see today’s temperatures every two hours, with the current time highlighted. The shaded part is daylight, and dotted columns mark hours with a chance of rain.
RAM cache
Section titled “RAM cache”The node keeps recently used files in memory, so opening them again does not need the drives. This cache is the ZFS ARC, the memory cache of the storage pool. The RAM cache card sets the most memory that cache may use. A larger cache makes files open faster, a smaller one leaves more memory for apps. The cache gives memory back when apps need it, so the limit is a ceiling, not memory set aside.
The limit matters most during heavy reading, such as a data integrity check, a backup or a large copy, when the cache would otherwise keep growing. The Dashboard shows how much of the limit the cache uses and how often it saves a trip to the drives.
Drag the slider to the new Size limit. The bubble above it shows the size, and the new limit takes effect as soon as you let go, without a reboot. It is kept when the node restarts.
Reboot restarts the node, after you confirm.
Shut down turns the node off, after you confirm. It stays off until you power it on again.
