Dear gluster users.

I would like to know if it is possible to define all aspects of a 
gluster setup manually.

for example i have in /var/lib/glusterd/vols

-rw-------. 1 root root 3.3K Jan 14 00:17 myvolume.bla1.data-brick.vol
-rw-------. 1 root root 3.3K Jan 14 00:17 myvolume.bla2.data-brick.vol
-rw-------. 1 root root 1.3K Jan 14 00:17 myvolume.tcp-fuse.vol
drwxr-xr-x. 2 root root   70 Jan 14 00:17 bricks
-rw-------. 1 root root   15 Jan 18 04:05 cksum
-rw-------. 1 root root  747 Jan 14 00:17 info
-rw-------. 1 root root   93 Jan 14 00:17 node_state.info
-rw-------. 1 root root   18 Jan 18 04:05 quota.cksum
-rw-------. 1 root root    0 Jan 13 21:37 quota.conf
drwxr-xr-x. 2 root root    6 Jan 18 04:05 run
-rw-------. 1 root root   13 Jan 14 00:17 snapd.info
-rw-------. 1 root root 1.5K Jan 14 00:17 trusted-myvolume.tcp-fuse.vol

file myvolume.bla1.data-brick.vol contains amongst other items a uuid

volume myvolume-posix
     type storage/posix
     option volume-id 1092f9c4-ce0e-4061-bff0-b0f51a4b35af
     option directory /bla/bla

is it possible to take ownership of this volume-id  and define this 

i know i can define the uuids of the peers which is already helpfull.

this question essentially applies to all aspects where uuids are 

The reason for pursuing this is that i want to be able to replace 
systems / bricks etc like for like.

Hopefully this means it becomes easier to swap hardware without the 
need to do any probing etc.

I am hoping this is possible.
thanks in advance
