Well, I had some more ideas and ran some more tests: 1. cp -r testdir ~/z1
This copied the testdir directory from the zfs pool into my home directory on the IDE boot drive, so not part of the zfs pool, and this worked. 2. cp -r ~/z1 . This copied the files back from my home directory on the IDE boot disk and into the ZFS pool. This worked. 3. cp -r z1 z2 This copied the files from the ZFS pool to another directory in the ZFS pool and this has not worked -- it hanged again, but differently this time. It copied a couple of files, then the hanged. The mouse wouldn't move, keyboard inactive, I hit loads of keys including ALT TAB and finally the mouse was back, the copying continued to copy 2 or 3 more files and then hanged again, this time no more files are being copied, and its hanged copying a different file from other times. So from these tests, it appears that copying the test directory out of the ZFS pool is successful, copying it in from outside the pool is successful, but reading and writing the files completely within the pool is failing. My gut instinct is that reading and writing purely within the pool is stressing the disks due to more I/O demands on the disks used for the ZFS pool, but this may be completely wrong.
