Environment

• Platform9 Managed OpenStack - All versions

• Glance

• Nova

Cause

• The path to store the snapshot and images is no longer present on the glance node or defined incorrectly in config files.

Resolution

1. Verify the paths configured for snapshot and images are available. If yes, check if the paths are correctly defined in the /etc/glance/glance-api.conf and /etc/pf9/imagelibrary/imagelibrary.conf config file.

/etc/glance/glance-api.conf

$ less /etc/glance/glance-api.conf
...
filesystem_store_datadir =
...
{% endtab %}
{% tab language="none" %}
// Click to edit code

/etc/pf9/imagelibrary/imagelibrary.conf

$ less /etc/pf9/imagelibrary/imagelibrary.conf
...
data_directory = 
...
{% endtab %}
{% tab language="none" %}
// Click to edit code

1. Restart the pf9-glance and imagelibrary service if the config files are changed for changes to take effect.
