On CentOS7 I get "No space left on device errors" just now..

[root@m-admin03 ~]# btrfs scrub start /

Sorry, I don't understand this..

In general, after a few weeks back in "Linuxland" (after more than 4 years FreeBSD/ZFS/jails).. Linux feels just sticky. FreeBSD is well-designed, secure and reliable compared to this.

Seen from FreeBSD, Linux is what Windows is to Linux: Just more "main stream" so everybody is scared of using "the exotic OS".

So I am quite ineffective at the moment, driving with the handbrake on.

As for the licensing: I could not be more bored. ZFS has a life outside Oracle.

If you need a storage appliance, use FreeNAS, I think. It beats Linux-based stuff by a mile.

Peter

Just tried installing Linux-4.1 from experimental on my desktop Jessie system to try btrfs.

Got this working. I had to back port nvidia-graphics-driver (from experimental) and libvdpau (from unstable) to Debian Jessie.
 
It seems to work fine.

Are there any resources for recommended setup details, e.g. recommended cron jobs for scrubbing btrfs, etc?

Anything else recommended with Linux-4.1? Apparently, from videos, manual balancing shouldn't be required any more?

Thanks
