zfs send/recv doesn't work on pipes #9

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Using zfs send | zfs recv doesn't work.

There is a workaround, which is to do:

mkfifo foo
zfs send > foo &
zfs recv < foo &

although this is clearly less than desirable

You can also work around this with a named pipe... which only really makes the
situation more confusing.

Can you post how to do it as a named pipe here so that others can compare that 
to the mkfifo approach ?
