Reliable data storage. :( Sadly, ZFS in FreeBSD is still very far from being stable. For example I have NFS servers running on ZFS, and they freeze about every week. It seems it's related to NFS. I can't even get to the debugger. After sending an NMI, the kernel writes "NMI ... going to debugger" eight times (those machines have 8 CPU cores) and nothing happens, I can only reset. Another machine just looses ZFS access (all processes stuck in IO) on i386 if I run rtorrent with unlimited bandwidth with some torrents, or some disk intensive spam filtering. Access to UFS filesystems are still OK. Also, running UFS and ZFS seems to have problems in 8-STABLE with UFS eating out memory from ZFS.
