– Basic ZFS Administration
– Creating a non-redundant and redundant ZFS Pools
– Creating ZFS Filesystem

ZFS on Linux might not be “in” the kernel, but it is production usable and integrated enough that Ubuntu ships with it and it’s even bootable. With it’s compression on the fly, snapshots and various other features, it is a filesystem that all Linux, FreeBSD and Solaris-based system administrators should consider and get to know. We’ll demonstrate some of these features and it’s applications in real life production systems. The ZFS filesystem sounds like it is the be-all-end-all of filesystems, but lets also show some of it’s limitations (given also it’s not integrated into the Linux kernel) to be aware of to not be caught by surprise.Imagine a filesystem that will detect (and fix) on-disk data corruption. Then image that same filesystem have already compressed the log files, not to mention it can provide near instantaneous snapshot recoveries. Not to mention capable of RAID6 levels of disk failure protection.
It’s called ZFS!
