ZFS on linux was originally an EL project. Ubuntu support came later.

I've been running ZoL on CentOS for years. Wonderful stuff. SysAdmin's
dream,
although we keep all ZoL boxes off any public access and update on a carefully 
tested schedule to ensure that no RPM version weirdness happens.

Ok, how's it scale on large filesystems? My manager was running some tests
this morning, 37TB f/s, and he said it seemed slow to respond. Also, dedup
seemed to take actual time - minutes. I saw him as he copied a 1G test
file to two or three other names, and it took time to go up, then level
off in size, with "size" being what we saw with df.
