2) Use gluster ::system getspec <volname>
I tried this but it never worked for me... whats the right way of using
this ?
For me.. it just returned back to shell w/o dumping the volfile at all!
The right way to use would be this:
#gluster --remote-host=<server> system:: getspec <volname>
This worked for me.. when I was on a non-peer which was in the same
subnet as the gluster host
But when i tried the same from my laptop (not in the same subnet) it
didn't work.. Pls see below
Also, you had indicated that this may not be a long supported option..
so wondering if it makes sense to use it in VDSM ?

So maybe its due to my gluster being old ?

It fails here too.. the cli returned error 240 instead of 255 (in my
laptop case) and server side had below error...

[glusterd-handshake.c:155:server_getspec] 0-management: Client
9.124.35.231:1023 doesn't support required op-version. Rejecting getspec
request.
So looks like for getspec to work the non-peer host and gluster host
versions should match exactly or something ...and if its so stringent, I
am not sure if it makes sense to use --remote-host approach in
VDSM..concern being there could be too many such version issues and VDSM
failing that Users getting it working... what say ?
thanx,
