Consider passing a JSON based block driver to "qemu-img commit"
$ qemu-img commit 'json:{"driver":"qcow2","file":{"driver":"gluster",\
"volume":"gv0","path":"sn1.qcow2",
"server":[{"type":\
"tcp","host":"10.73.199.197","port":"24007"}]},}'
Currently it will commit the content and then report an incredibly
useless error message when trying to re-open the committed image:
qemu-img: invalid URI
Usage: file=gluster[+transport]://[host[:port]]volume/path[?socket=...][,file.debug=N][,file.logfile=/path/filename.log]
With this fix we get:
qemu-img: invalid URI json:{"server.0.host": "10.73.199.197",
"driver": "gluster", "path": "luks.qcow2", "server.0.type":
"tcp", "server.0.port": "24007", "volume": "gv0"}
Of course the root cause problem still exists, but now we know
what actually needs fixing.
