I tried this but it never worked for me... whats the right way of
For me.. it just returned back to shell w/o dumping the volfile at
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 ?
Supporting --remote-host for other volume operations doesn't look like
a good idea. But we can retain the interface for fetching a volume
From my laptop

and on server side.. the below error was reported...

So maybe its due to my gluster being old ?
Yes, this is related to interaction between 3.2 and a later version.

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
188.8.131.52:1023 doesn't support required op-version. Rejecting getspec
This seems to be related to the recent op-version implementation.
CC'ing Kaushal for that.
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 ?
3.3 and 3.4 should be interoperable. Anything that impedes this should
be treated as a bug. If you have a real need for the fetch spec
interface to work with --remote-host, we can retain it.
