State of the system: > > =E2=80=8B Replying to my own message in case someone else is searching for an answer for this :-). I got a clue after posting this message. There clearly seems to be a bug at least in freebsd 11.0. It has to do with the swap file. What I forgot to mention in my earlier post was that =E2=80=8BI dont have a swap partition since I just put the freebsd root ov= er the ubuntu partition. And I had created a swap file based on the instructions in 11.12.2 Creating a swap file. https://www.freebsd.org/doc/handbook/adding-swap-space.html I got a clue from the freebsd-forums: https://forums.freebsd.org/threads/58266/ If the link is down (for some reason, I see the server is down quite often these days), use the below cached link: https://webcache.googleusercontent.com/search?q=3Dcache:y1bJLmSEjWUJ:https:= //forums.freebsd.org/threads/58266/+&cd=3D2&hl=3Den&ct=3Dclnk&gl=3Din So, I just did a swapoff -La and then ran the split command again - no issues whatsover! I will raise a bug report -- and try to support with logs if needed. Thanks, Gautam
