So it's a 2-bay RAID enclosure with either USB or eSATA connections. One of the two bays are occupied, and how is the enclosure being connected? > The ZFS set was getting full; something like only 50gig free. You probably have two zpools - one is the mirrored "rpool", while the other is your data pool, say, "tank". Am I understanding that it's "tank" that has 50 GB (out of 4TB) free, while "rpool" does not have any problems? > I was starting > file copies off the server to an external drive via an SMB client, and going > to bed, to wake up and find the process had frozen.

Is this external drive the RAID enclosure discussed above, that you connected via Ethernet and it shows up as an SMB device, or is this on a separate computer? My thoughts are: 1) if "rpool" is not full, then the system should not freeze. Depending on any snapshots, even removing files from "tank" may fail and if you do it via SMB, as opposed to over a local command line, you won't know why. Could you try logging on to the system, and copying the files from the server to a client, so you see any local error messages on the command line? 2) if, for some reason, data loss crept in, ZFS will refuse to return bad data. Could you run a "zpool scrub" on each of the pools and then verify that they are healthy? > Could the lack of free space on the ZFS set also have caused a problem, or > is it likely that the weight of another problem, possibly the USB external > drive connection, caused it to keel over? Not sure if it will help, but could you give details on what the enclosure is (brand/model), and what motherboard/USB controller are on the server?
