[OpenIndiana-discuss] Upgrading from oi_148 to oi_151 - some clarification please

[ken mays]

Carl,
 
The ZFS pool 28 improvements/bug fixes in oi_151 are coming from the Illumos project and can be seen within ZFS-related patches from Illumos_gate (see link from oi_151 project page and snapshot version used). 
 
Just as a note, the main differences between ZFS pool 28 and ZFS pool 31 are:
 

6977913 RAID-Z/mirror hybrid allocator

4854202 ZFS data set encryption

6980669 zfs rename -r is slow, causes appliance UI to hang
 
ZFS pools 29-31+ are not in 'major use' by other OS distros outside of the official Solaris product releases coming from Oracle.

zpool upgrade -v
This system is currently running ZFS pool version 28.

The following versions are supported:

VER  DESCRIPTION
---  --------------------------------------------------------
1   Initial ZFS version
2   Ditto blocks (replicated metadata)
3   Hot spares and double parity RAID-Z
4   zpool history
5   Compression using the gzip algorithm
6   bootfs pool property
7   Separate intent log devices
8   Delegated administration
9   refquota and refreservation properties
10  Cache devices
11  Improved scrub performance
12  Snapshot properties
13  snapused property
14  passthrough-x aclinherit
15  user/group space accounting
16  stmf property support
17  Triple-parity RAID-Z
18  Snapshot user holds
19  Log device removal
20  Compression using zle (zero-length encoding)
21  Deduplication
22  Received properties
23  Slim ZIL
24  System attributes
25  Improved scrub stats
26  Improved snapshot deletion performance
27  Improved snapshot creation performance
28  Multiple vdev replacements

For more information on a particular version, including supported releases,
see the ZFS Administration Guide.

So not according to zpool -v, oi_151 seems to be still running ZFS pool 28.  So what're the ZFS improvements ("More ZFS improvements") in oi_151?  Where do I go looking to see what's changed?

Thank you

Carl
