@SVN rev 192498 on 2009-05-20 23:34:59Z by kmacy

MFC ZFS version 13. This includes the changes by pjd (see original message
below) as well as the following:

- the recurring deadlock was fixed by deferring vinactive to a dedicated thread

- zfs boot for all pool types now works
      Submitted by: dfr

- kmem now goes up to 512GB so arc is now limited by physmem

- the arc now experiences backpressure from the vm (which can be too
much - but this allows ZFS to work without any tunables on amd64)

- frequently recurring LOR in the ARC fixed

- zfs send coredump fix

- fixes for various PRs

Supported by: Barrett Lyon, BitGravity

Revision 185029 - (view) (annotate) - [select for diffs]
Modified Mon Nov 17 20:49:29 2008 UTC (6 months ago) by pjd
File length: 38244 byte(s)
Diff to previous 177698

Update ZFS from version 6 to 13 and bring some FreeBSD-specific changes.

This bring huge amount of changes, I'll enumerate only user-visible changes:

- Delegated Administration

       Allows regular users to perform ZFS operations, like file system
       creation, snapshot creation, etc.

- L2ARC

       Level 2 cache for ZFS - allows to use additional disks for cache.
       Huge performance improvements mostly for random read of mostly
       static content.

- slog

       Allow to use additional disks for ZFS Intent Log to speed up
       operations like fsync(2).

- vfs.zfs.super_owner

       Allows regular users to perform privileged operations on files stored
       on ZFS file systems owned by him. Very careful with this one.

- chflags(2)

       Not all the flags are supported. This still needs work.

- ZFSBoot

       Support to boot off of ZFS pool. Not finished, AFAIK.

       Submitted by:   dfr

- Snapshot properties

- New failure modes

       Before if write requested failed, system paniced. Now one
       can select from one of three failure modes:

       Before if write requested failed, system paniced. Now one
       can select from one of three failure modes:
       - panic - panic on write error
       - wait - wait for disk to reappear
       - continue - serve read requests if possible, block write requests

- Refquota, refreservation properties

       Just quota and reservation properties, but don't count space consumed
       by children file systems, clones and snapshots.

 - Sparse volumes

       ZVOLs that don't reserve space in the pool.

 - External attributes

       Compatible with extattr(2).

 - NFSv4-ACLs

       Not sure about the status, might not be complete yet.

 - Creation-time properties

 - Regression tests for zpool(8) command.
