       Had not realised until now that ZFS on Linux is highly controversial and not welcome at all:Greg KH on linux-kernel: "My tolerance for ZFS is pretty non-existant. Sun explicitly did not want their code to work on Linux, so why would we do extra work to get their code to work properly?"¹It appears that the upcoming Linux 5.0 & ZFS don't go together very well.Several of my clients have adopted ZFS-on-Linux for their servers and I've been busily migrating…__¹ https://marc.info/?l=linux-kernel&m=154714516832389&w=2

       them to #FreeBSD for obvious reasons such as it being the platform on which OpenZFS is developed.This latest spate will simply make my task easier.I have often seen large Linux systems fail in mysterious ways, be it performance or losing data, which has been an "easy push" towards #FreeBSD on the server side.

       @cynicalsecurity did you see that freebsd recently announced they are switching to ZoL?https://lists.freebsd.org/pipermail/freebsd-fs/2018-December/027085.html

       @phessler thanks for sharing, as a ZoF user in  couple of small shops. I've always found it really stable.  When I looked at ZoL  ( around 2013 ) it was not as stable as ZoF and that was fundamental to moving several hosts to FreeBSD.

       @boneidol I hope it all works out, but I am sceptical.  I just hope the in-fighting doesn't damage the on-disk data :flan_sad:.

       @phessler @boneidol I run linux on the majority of my servers and would see a change in file system as requiring a whole new deployment. It could be just that I am not 100% great at upgrading these core systems but for me personally I spin up another box, run my migration scripts and then update the load balancer to add the new system to its pool while removing the old one for scrapping.I'd fear loosing data otherwise.

       @carbontwelve @boneidol oh sure, major changes in FS should get a clean install, restore from backup treatment.but I'm more worried about subtle changes in the interfaces, and point releases causing problems.  Checksums are pretty critical to ZFS, so them doing weird things with non-exported symbols gives me some pause.
