 Has anyone noodled through the details of pxeboot and pc-sysinstall for
 automated installs?

 I have working configurations for pxeboot and sysinstall for 8.1-RELEASE and
 prior.

 What are the gotchas for 9.0-CURRENT?

 I have lots of testing time available.

I have done something in this realm called vCloudFreeBSD but I have
not set it up as a pxeboot.   I am sure you could very easily.

vCloudBSD is meant to auto install to the first available disk.   This
ISO contains the Puppet packages and will automatically join a puppet
server and self configure but you can pull the bits and pieces out and
roll your own disk using the pfSense builder framework or the
traditional make release methods.

If you are interested in learning more I talk about it in my blog.

Re: [CFT] ZFS ACL and rrwlock speedup

2010-08-27 Thread Scott Ullrich 
2010/8/24 Martin Matuska m...@freebsd.org:
 Dear FreeBSD community,

 in my last CFT I presented a patch that improves ZFS write speed. There
 have been easily portable improvements on the read side in OpenSolaris,
 too. Of course, the improvement here is by far not that dramatic as in
 the zfs_metaslab.patch, but OpenSolaris developers claim this also
 improves the speed of stat() calls.

 I would like to Call For Testing for the following patch (9-CURRENT):
 http://people.freebsd.org/~mm/patches/zfs/zfs_abe_stat_rrwlock.patch

 This patch adds the following:
 - better ACL caching and speedup of the ACL permission checks
 - lowered mutex contention in the read/writer lock (rrwlock)
 - several bugfixes

 This patch does not interfere with the zfs_metaslab.patch

 To apply the patch against 8-STABLE, you need to apply the v15 update first:
 http://people.freebsd.org/~mm/patches/zfs/v15/stable-8-v15.patch

 The patch imports the following OpenSolaris onnv revisions:
 9749 (without zlook), 9866, 9981, 10143, 10232, 10295, 10250, 10269

 And covers the following OpenSolaris Bug IDs:
 6802734 Support for Access Based Enumeration (not used on FreeBSD)
 6844861 inconsistent xattr readdir behavior with too-small buffer
 6848431 zfs with rstchown=0 or file_chown_self privilege allows user to
 take ownership
 6775100 stat() performance on files on zfs should be improved
 6827779 rrwlock is overly protective of its counters
 6857433 memory leaks found at: zfs_acl_alloc/zfs_acl_node_alloc
 6860318 truncate() on zfsroot succeeds when file has a component of its
 path set without access permission
 6865875 zfs sometimes incorrectly giving search access to a dir
 6870564 panic in zfs_getsecattr
 6867395 zpool_upgrade_007_pos testcase panic'd with BAD TRAP: type=e
 (#pf Page fault)
 6868276 zfs_rezget() can be hazardous when znode has a cached ACL

So far so good on this patch as well.  Running it for a good 3 days
with 4TB and it is nice and fast (220MB/sec for 1.5 TB drives).

  Thank you, I have updated the v15 patch for 8-STABLE.

I have been running your patch for a couple days now and no issues.

Nice work!
