comment ZFS - Is RAIDZ-1 really that bad?
I'm using 4 WD RE4-GP drives, which have <1 in 10^15 non-recoverable read errors.

Thanks for that explanation. That makes a lot of sense and matches with what I've learned about ZFS so far. I have actually reloaded my server with FreeNAS already and went with the RAIDZ-1 configuration. I have it set to scrub once a month. Do you think that is often enough or would you recommend more frequent scrubs? The rampant layering violation is my favorite feature of ZFS :-)

Thanks for your help in Chat. Going to go with RAIDZ since I need the space and performance isn't as much of a concern.

Thank you for the link to your workflow. Very informative. I now feel more undecided than ever, ha.

I'm a terminal guy myself, so I'm definitely not switching for the GUI. Mostly, I just need a stable file system that (as much as is possible) guarantees the integrity of the files stored on it. And I was hoping to gain some space in the process. I've seen a lot of issues reported for ZoL, many of them relating to Ubuntu OS upgrades. groups.google.com/a/zfsonlinux.org/forum/#!searchin/zfs-discuss/… Not trying to be a pain. Just explaining why I think what I think. I'm certainly open to correction.

Why avoid FreeNAS? The reason I intend to switch is because ZFS on Linux uses the Solaris Emulation Layer, which can break with a simple Linux kernel update and potentially nuke the zpool. ZFS runs natively on Unix-/BSD-based OSes and doesn't have that problem. confessionsofalinuxpenguin.blogspot.com/2012/09/…

Not sure how this is off-topic. I'm asking for advice about the proper file system configuration for a server.

Forgot to mention that the OS lives on a separate drive. Sorry. What I'm wanting from ZFS that the XFS RAID10 doesn't have is checksum data verification that can detect (and transparently fix) silent data errors (a bit flipped on the drive, and the HDD has no idea). I don't believe XFS is able to do this.
