* We may need a libefi replacement. It appears libefi is used
|
|
to determine if the device passed to zpool is a 'whole device'
|
|
or just a partition of a device. 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. This is needed by Lustre for object creation + LAST_ID
|
|
updates, unlink + llog updates, etc. Conceptually this isn't very
|
|
much work for a phase tree, but I've never looked at the ZFS code."
|
|
|
|
* Design and implement mechanism for viewing and modifying OST content
|
|
from user space (by manipulating datasets/objects), possibly
|
|
by implementing scaled down file system interface.
