 Can you confirm that doing rsync with this fuse version is stable?

I'm sorry but I've never even tried rsync on top of a fuse mount.
 
 Can you please tell us which fuse-based file system have you used?

Mostly sysutils/fusefs-smbnetfs to access file servers and sometimes
sysutils/fusefs-ntfs with Win XP and Win 7 disks.

Re: Fuse on FreeBSD 9.2

2013-10-08 Thread Yamagi Burmeister
There's already a backport which can be found here:
http://people.freebsd.org/~flo/fusefs-kmod.tar.bz2

1. Download, untar and replace your existing sysutils/fusefs-kmod
   port with it. Open the Makefile and add NO_STAGE= yes to it.
2. cd sysutils/fusefs-kmod ; make makesum ; make deinstall reinstall
   clean
4. Rebuild sysutils/fusefs-libs and all fuse filesystems (don't 
   know if that's necessary but it doesn't hurt either).

I've been running with this kernel module on FreeBSD 9-STABLE,
9.1 and 9.2 four about one year without any problem. I don't
know why flo@ never committed his work.

  I'm willing to pay for the fix.
  
   
 
 I think the fix is the new from-scratch fuse module in FreeBSD 10,
 which in my experience works flawlessly. Perhaps you should instead see
 if someone is willing to backport that fuse module to 9.x?

 I'm sorry but I've never even tried rsync on top of a fuse mount.

I've just rsynced ~25GB data from an smbnetfs mount to zfs and back to
the smbnetfs mount. No problems so far. That's of course only a first
test but apparently there are no obvious problems / panics.

Re: Fwd: Intel microcode update

2013-03-22 Thread Yamagi Burmeister
Hi,
yes the microcode file provided by Intel is incompatible with FreeBSD.
You'll need to split it into individual files for each CPU. I vaguely
remeber that there was a script or something like that bundled with one
of the ports. Nevertheless attached is a small C program which does the
same. It's not written by me, I just found it somewhere on the web.

Ciao,
Yamagi

 Subject : Intel microcode update
  Forwarded message 
 
  
 Hi, 
  
 I was wondering how to update microcode of an Intel CPU and came across 
 cpucontrol and sysutils/devcpu-data . But last mentioned port is not 
 up-to-date 
 anymore. I searched Intel's webpages for microcode updates and found archives 
 for Linux containing one single microcode.dat file. Could someone tell me if 
 that file is compatible with FreeBSD? As devcpu-data installs .fw files it 
 might be proper to convert/compile microcode.dat in some way. How? 
  
 Regards, 
 kaltheat

Re: SMP Version of tar

Tim Kientzle t...@kientzle.com wrote:

 There are a few different parallel command-line compressors and decompressors 
 in ports; experiment a lot (with large files being read from and/or written 
 to disk) and see what the real effect is.  In particular, some decompression 
 algorithms are actually faster than memcpy() when run on a single processor.  
 Parallelizing such algorithms is not likely to help much in the real world.
 
 The two popular algorithms I would expect to benefit most are bzip2 
 compression and lzma compression (targeting xz or lzip format).  For 
 decompression, bzip2 is block-oriented so fits SMP pretty naturally.  Other 
 popular algorithms are stream-oriented and less amenable to parallelization.
 
 Take a careful look at pbzip2, which is a parallelized bzip2/bunzip2 
 implementation that's already under a BSD license.  You should be able to get 
 a lot of ideas about how to implement a parallel compression algorithm.  
 Better yet, you might be able to reuse a lot of the existing pbzip2 code.
 
 Mark Adler's pigz is also worth studying.  It's also license-friendly, and is 
 built on top of regular zlib, which is a nice technique when it's feasible.

Just a small note: There's a parallel implementation of xz called
pixz. It's build atop of liblzma and libarchiv and stands under a 
BSD style license. See: https://github.com/vasi/pixz Maybe it's
possible to reuse most of the code.

Re: What's cooking for FreeBSD on wiki

 Since I have less free time than necessary to properly maintain the
 What's cooking page(s), I've transitioned the one for FreeBSD 10, and
 hopefully future versions, to the FreeBSD wiki:

 This reduces the bus factor for this page and also allows everyone to
 add new information they think is necessary.
 
 I'll also participate in maintaining the wiki page, but please don't
 wait for me if you see something missing from it :)

Lars Engels asked me if I would volunteer to help keeping that wiki
page up to date. Since my day job requires me to read nearly every
commit message and I'm writing all the FreeBSD related news for the
german BSDForen.de community, I agreed. But, of course, any help is
welcome. :)

Re: Tyan S2895 7.1 amd64 4Gb RAM support?

 Hi,
 
 I've a Tyan S2895 (bios 1.04), w/10Gb of ECC RAM onboard using 2 * Opteron 
 285's. The machine used to run WinXP x64, and Vista x64 (mostly doing video 
 production, ray tracing etc.)
 
 I recently switched this machine to FreeBSD 7.1 amd64 - to run ZFS on it, 
 but I've been having horrific problems with it.

Hello,
I'm using some S2895 for various purposes, as webservers,
databaseservers and workstations. Most of them are populated using 2 *
Opteron 265 in stepping E2. They work like a charm _after_ upgrading the
BIOS to version 1.05e_beta or later[1]. But it's necessary to use
/boot/loader from 7.0 since later version won't work to some bios-bugs.

Ciao,
Yamagi
