Using a shared Lightroom catalog on a SAN

  • Updated 3 years ago
We are setting up a SAN/DAM network. We will have at least three workstations, connected to the SAN via fiber channel. We would like to use a single Lightroom catalog that would live with the photos on the SAN and be able to have that catalog open on multiple workstations simultaneously so that all users at all workstations can have access to work done by anyone else. I was told that this is not possible. If this can be worked into the engineering of future versions of Lightroom, that would be great. Any further questions about this, please contact me.

LR is single-user with the catalog on a local drive.

Hi Steve, Thank you for your response. I understand that this is the way it works now. It would be great to add the technology that I discussed on future versions of Lightroom for use in a shared environment.

People have asked for this over the years, but a multi-user client-server is significantly different than a single-user system. Microsoft Access is one of the last multi-user database systems that used the file system rather than client-server that everything uses nowadays. The SQLLite that LR uses as it's underlying database isn't multi-user.

Exporting a subset of photos as a catalog and reimporting them into the master catalog, later, is the assembly-line approach that LR accommodates, now. It does require more planning and structure than multiple users working on the same set of photos whenever they want.
