Hardware, Embedded Systems ACM's latest journal had an interesting article about RAID which suggested it might be time for triple parity raid. "How much longer will current RAID techniques persevere? The RAID levels were codified in the late 1980s; double-parity RAID, known as RAID-6, is the current standard for high-availability, space-efficient storage. The incredible growth of hard-drive capacities, however, could impose serious limitations on the reliability even of RAID-6 systems. Recent trends in hard drives show that triple-parity RAID must soon become pervasive."

I worked on the Linux ZFS port using FUSE.

1. Some people feel that FUSE filesystems are second class citizens on Linux. I happen to agree, but you may not.

2. Quite apart from the fact that it's a FUSE filesystem, zfs-fuse has bugs. Some people wake up one morning and their pools don't import. Sometimes this can be fixed with specialized single-purpose tools from the author and sometimes they can't. For more zfs-fuse failures, check the mailing list.

3. If you think ZFS is neat, I strongly recommend throwing your support behind btrfs. It's not as good as ZFS, but you will eventually be able to trust your data to it on Linux.
