These are all I could find from Wikipedia and other sources. If you’re aware of any other ones please share them in comments and I’ll add them to the list.

As we all know no experiment is valid unless verifiable. I wanted be sure that the transparent compression was actually working so I set up a sample zfs volume and purposefully made some files that i knew would compress really well. I grabbed their sizes, transferred them to another machine without zfs, and compared the size. It works.

1. Create the zfs filesystem
root@machine1:~# zfs create rpool/ztest
root@machine1:~# zfs set mountpoint=/ztest rpool/ztest

as soon as you do this /ztest shows up in the filesystem
root@machine1:~# ls /ztest/

2. enable compression and set it use gzip at level 6 (default)
root@machine1:/ztest# zfs set compression=gzip rpool/ztest

3. create some files you know will compress well
time for i in $(seq 1 3); do echo -n “file${i} “; echo $(seq 1 10000000) >> file${i} 2>&1; done

4. check the compression ratio
root@machine1:/ztest# zfs get compressratio rpool/ztest
NAME         PROPERTY       VALUE        SOURCE
rpool/ztest  compressratio  3.69x        -

5. verify the compression is working by transferring the file to a machine without such an awesome FS, and checking the filesize there
root@machine1:/ztest# du -sh file1
23M     file1
scp -rvp /ztest/file1 root@machine2:/root/file1

root@machine2]# du -sh file1
83M    file1

Conclusion: transparent compression is working, and working rather well on a file I made to be easily compressed.
