I used to love pv, but I had ZFS send and recv hang many times when I was using pv in the pipeline and I was never sure why but after I stopped using pv in the pipeline and started using the verbose flag of the ZFS command on the receive side instead which provides enough output for me to see that it’s progressing and haven’t had those kinds of problems since.

Searching now it seems indeed that up until recently this was a problem other people have been having too. For example the recent forum thread https://forums.freebsd.org/threads/zfs-send-hanging.94994/ where they were discussing which version this was fixed in and someone saying that the latest available version to them from the packages was still a bit too old.

Changing the endianness of the data?

A sibling comment talked about “UwU names”. Not sure exactly if they are referring to “tokio” or something else. But if it’s tokio, they might find this informative:

> I enjoyed visiting Tokio (Tokyo) the city and I liked the "io" suffix and how it plays w/ Mio as well. I don't know... naming is hard so I didn't spend too much time thinking about it.

From the original release announcement of tokio on r/rust on Reddit.

And also to the sibling commenter, if tokio is a problematic name to you:

Would either of the following names be equally problematic or not?

- Chicago. Code name for Windows 95, and also the name of a city in the USA. https://en.wikipedia.org/wiki/Development_of_Windows_95 https://en.wikipedia.org/wiki/Chicago

- Oslo. Name of a team working on OpenStack, and also appears in their package names. Oslo is the capital of Norway. https://wiki.openstack.org/wiki/Oslo https://en.wikipedia.org/wiki/Oslo

If yes, why? If no, also why?

Super neat! :D
