Hi Tim, Thanks for having a look. The 'utf8only' setting is set to off. Important bit of additional information: We only seem to have this problem when copying to a zfs filesystem with the casesensitivity=mixed property. We need this because the filesystem will eventually be shared over NFS and

[zfs-discuss] Split responsibility for data with ZFS

Large sites that have centralized their data with a SAN typically have a storage device export block-oriented storage to a server, with a fibre-channel or Iscsi connection between the two. The server sees this as a single virtual disk. On the storage device, the blocks of data may be spread
