Re: [Moosefs-users] Best FileSystem for chunkers.

Hey Atom,

Linux ZFS isn't all fuse, yes there is a ZFS fuse implementation but also a kernel module implementation by zfsonlinux.org.

Enjoy!

I use ZFS on FreeBSD, which is one of the main reasons I use FreeBSD on 
my chunk servers.

Good:
* Compression, 1.16x in my environment
* zraid
* probably improved performance (I haven't done a comparison on MooseFS 
but saw better performance over UFS for "standard" file system use)
* Easy to carve up for other uses on the same server

Bad:
* high RAM requirement

Ugly:
* FreeBSD is tricky to build with bootable ZFS
* Linux ZFS is FUSE.
