This is a rather difficult process considering that a lot of things have changed between 3.0 and now. The recommended approach would be to copy over data from the old volume (running 3.0) to a new volume (with 3.10) if you can. > I tried on a test machine, to install newer version of gluster (3.7) and > created the volume with "volume create" and using the same bricks and it > looks like the files are visible, but since this is only a test set of > files, I am not actually sure, that this is the right thing to do. > > Can someone give me some recommendation what is best thing to do? > Do you have more details on the volume files used with 3.0? Have you figured out the right volume type that you would need to use with "volume create"? Regards, Vijay
