In the short term I think we + can simply treat everything as a partition and be alright. + +* We also do not have support for getting Solaris style device + ids which is done when a zpool is setup. We may or may not + be able to live without this, the jury is still out. + +----------------------------------------------------------------------- + +* Port zvol (ZFS volume interface). + +* Port zpl (ZFS posix interface). + +* Port lustre fsfilt interface to use DMU. + +* Andreas issue #1: + "the maximum allocation DMU "blocksize" was 128kB and it would be better + to be able to get 1MB contiguous allocations for best performance" + +* Andreas issue #2: + "there would need to be some work done to allow multiple operations to + be atomic.
