Chapter 26. Monitoring Stratis file systems

download PDF

As a Stratis user, you can view information about Stratis volumes on your system to monitor their state and free space.

26.1. Stratis sizes reported by different utilities

This section explains the difference between Stratis sizes reported by standard utilities such as df and the stratis utility.

Standard Linux utilities such as df report the size of the XFS file system layer on Stratis, which is 1 TiB. This is not useful information, because the actual storage usage of Stratis is less due to thin provisioning, and also because Stratis automatically grows the file system when the XFS layer is close to full.

Important

Regularly monitor the amount of data written to your Stratis file systems, which is reported as the Total Physical Used value. Make sure it does not exceed the Total Physical Size value.

    my-pool    /dev/sdb            9.10 TiB  In-use  Data
  • To display information about all Stratis pools on your system:

    # stratis pool
    
    Name    Total Physical Size  Total Physical Used
    my-pool            9.10 TiB              598 MiB
  • To display information about all Stratis file systems on your system:
