Hi Luis,
What is the full volume path? Please go to the volume path and check if volume.id file is present in that path. Aslo are you able to open documents within the volume in question in LF client?
If there is no such file under the folder, you can review the following example and perform similar steps outlined. This example assumes that the fixed volume path you want to use is C:\LF\Volume and the volume files are already there.
1. Rename the Volume folder to C:\LF\Volume2
2. Create a new blank folder named Volume
3. Go to LF admin console, change the fixed path of the volume to C:\LF\Volume
4. Rename the Volume folder to VolumeTemp
5. Rename the Volume2 folder to Volume
Check if you can open documents within the volume and you can change the properties of the volume. And then you can delete the VolumeTemp folder.
Regards
