Preview: upcoming Illumos ZFS changes in code review phase

[Martin Matuska]

Hi everyone,

ZFS development in Illumos seems to be going on.
I am in touch with the developers and closely following the activity on
the mailing lists.
Here is a preview of the patches and enhancements that are in the code
review phase:

1.)
show zfs ioctl args in truss (might be of interest for us)
https://www.illumos.org/issues/1688
WEBREV: http://yalms.org/cr/truss-zfs/

2.<http://bugs.delphix.com:8082/show_bug.cgi?id=1644>)
1644 add ZFS "clones" property
https://www.illumos.org/issues/1644

1645 add ZFS "written" and "written at ..." properties
https://www.illumos.org/issues/1645

1646 "zfs send" should estimate size of stream
https://www.illumos.org/issues/1646

1647 "zfs destroy" should determine space reclaimed by destroying
multiple snapshots
https://www.illumos.org/issues/1647

WEBREV: http://code.delphix.com/webrev-props/

3.)
persistent 'comment' field for a zpool
https://www.illumos.org/issues/1693
WEBREV: http://www.kebe.com/~danmcd/webrevs/hackathon/zfs-comment/

4.)
"zpool reguid" command (change zpool's guid number)
WEBREV: http://dev1.illumos.org/~gdamore/reguid/

Some of the patches have already received lots of comments so the final
code added to Illumos is going to be different.
