Find out the state of a pool, whether or not it has errored, what the results of its latest scan are, and what drives are in it.
Step by Step
- Log into your creative.space node with a user account assigned the ‘System Admin’ or ‘System Monitor’ role.
- Go to the System page.
- Click on the ‘Pool Name’ you want to see the information for.
- A card will pop up showing the ‘Pool Information’.
What is a Pool?
A pool is a group of drives that work together to hold your data. All nodes have at least one pool.
The physical drives in your server will have data spread across them. By separating data management into pools and spaces, you are able to divide your storage into separate volumes (spaces) that each have access to the full performance and capacity of the storage hardware (pools).
Understanding Pool Information
State
The state of a pool describes whether or not it can be used for storing data.
State | What You Need to Do |
ONLINE | The pool can be used to store data. All of its drives are working correctly. |
DEGRADED | The pool can be used to store data, but one or more of its drives have failed. Replace the failed drive immediately to avoid data loss. |
UNAVAIL | The pool cannot be used to store data. Too many of its drives have failed. Replace the failed drives immediately so that the pool can once again be used to store data. |
Errors
When a drive does not correctly store or retrieve data an error occurs. Although a pool can usually fix a certain amount of errors, it is a sign that a drive in the pool is about to fail, and will need to be replaced. Keep in mind that while a pool can tolerate a drive failure, it is very important to replace the failed drive immediately to prevent data loss.
Scan
A scan is when a pool periodically checks all of its drives to make sure they are functioning correctly. If any of the drives generate errors, the pool takes extra steps to repair the errors. Pools scan their drives on a weekly basis to keep your data safe.
Config
A config is a list of drives in a pool. You can check the config to see the number of drives in a pool, and the status of each drive.
Drives
A drive is the physical hardware on which your data is stored. Most pools have either 12TB or 16TB hard drives, or 1, 2 or 4TB solid state drives. A drive can either be online or faulted. If a drive is online then it is correctly storing and retrieving the data the pool sends it. If it is faulted then it is either generating errors, or it is missing. A faulted drive is usually either broken, about to break, or missing from the node entirely.
