I have upgraded successfully from glusterfs-server 3.7 to 7.7 directly offline .
Glusterfs-server 7.7 can't work on centos 7.0 ,after update the os to
centos 7.8 ,glusterfs-servers work as expected ! After upgrade ,I added a
arbiter node.

Hi,
I believe you can do an offline upgrade (I have never tried upgrading from 3.7
to 7.7, so there might be issues).
If you want to do a fresh install, after installing the 7.7 packages, you can
use the same old bricks to create the volumes. but you need to add force at the
end of volume create command.

hi everyone!
I found It is hard to upgrade from a gluster version from 3.7.6 to 7.7,so I
remove all the install package and delete all config file except the brick, and
I resinstall the glusterfs 7.7, then reconfig the same volume name but use a
temp brick.after everything is ok ,then i stop the volume and replace the old
brick , change the brick volume id as the new volume id , at last start the
volume successfully.
What I want to know is if this is the right way to upgrade .
