[pve-devel] [PATCH 2/6] qemu_drive_mirror : handle multiple jobs

Oh, works even better.



#socat UNIX-LISTEN:/tmp/foo.sock  TCP:8.8.8.8:1234,connect-timeout=1


# drive_mirror -n drive-scsi0 nbd:unix:/tmp/foo.sock
Failed to read data

(and socat is killed)

A nasty trick, but I suppose it gets the job done for now (until someone 
sends a patch upstream). Btw. before you go around killing socats: it has 
a `connect-timeout` option (which is almost surprising).
