Re: [Gluster-users] Indexing/Importing existing files on disk
Hi! Thank you for the response The Volume I want to import the files into is a distributed volume with 9 bricks. (more info at the bottom). It seems I failed to include the referenced page ( https://rosenha.in/blog/2016/10/migrating-to-gluster-with-existing-data/) in my last email, apologies for that.
