Where are Medulla imaging masters stored?

Applies to: Medulla – Imaging
Version: All versions
Environment: On-Premise
Category: Imaging / Masters / Administration

Medulla imaging masters are stored on the Imaging servers in the following directory:

/var/lib/pulse2/masters

In this folder, you will find several subdirectories with names in UUID format.

Each folder corresponds to the files for a specific master.

Example:

/var/lib/pulse2/masters/<uuid>

Each folder contains the complete data for an imaging master.

How do you determine which master a UUID corresponds to?

The easiest way is to query the imaging database to find the correspondence between:

  • The master’s name
  • Its UUID
  • Its storage path

1. Connect to MariaDB

From the Imaging server:

mysql

2. Run the SQL query

select id, name, uuid, path
from imaging.Image;

3. View the results

Example result:

+----+--------------------------+--------------------------------------+----------------------------------------------------------------------+
| id | name                     | uuid                                 | path                                                                 |
+----+--------------------------+--------------------------------------+----------------------------------------------------------------------+
|  1 | Master Windows 11 Pro FR | 4dddf514-c4f6-11f0-ade0-bc2411916521 | /var/lib/pulse2/masters/4dddf514-c4f6-11f0-ade0-bc2411916521        |
+----+--------------------------+--------------------------------------+----------------------------------------------------------------------+

In this example:

  • The master is named Master Windows 11 Pro FR
  • Its UUID is: 4dddf514-c4f6-11f0-ade0-bc2411916521
  • Its files are stored in: 
    /var/lib/pulse2/masters/4dddf514-c4f6-11f0-ade0-bc2411916521

Important:
Do not manually modify or delete a master folder without first verifying its correspondence in the imaging database. Incorrect deletion may render a master unavailable in Medulla.

What is this used for?
  • To identify a master stored on disk
  • Free up disk space
  • To troubleshoot a corrupted master
  • Perform a backup or transfer of a master
