freebsd8.0-STABLE + ext4

sycamorex · 07-05-2010, 06:35 PM

I've installed FreeBSD8.0-STABLE amd64 and must say: wow!
So far I've been only surprised by it. It took me half a day to configure it, but I enjoyed it. I remember when I tried it 3-4 years ago I couldn't get through the basic configuration but it was before I used slackware

I haven't researched it, but a few things still need to be solved:

1. Only OSS seems to be available on the system.
2. Need to get flash working
3. Need to find out which sound module needs to be loaded. At the moment I load a meta one.

These are things I'm going to do tomorrow. The only worrying thing for me is that it seems that ext4 is not yet supported. I've come across some posts from 2009 which stated that one couldn't mount ext4 on freebsd (not yet). That would probably be the biggest show-stopper for me as all my data is on ext4 filesystems.

Could anyone give me an update on the state of ext4 in FreeBSD8.0-STABLE?

Thank you

Ext2fs Status report (Summer of Code 2009)

URL: http://wiki.freebsd.org/SOC2009AdityaSarawgi

Contact: Aditya Sarawgi <sarawgi.aditya@gmail.com>

FreeBSD's ext2fs had some parts under GPL. The aim of my project was to rewrite those parts and free ext2fs from GPL. I have been successful in rewriting the parts and NetBSD's ext2fs was a great help in this. Certain critical parts under GPL were also removed due to which the write performance suffered. I also implemented Orlov Block Allocator for ext2fs. Currently I am planning to make ext2fs Multiprocessor Safe (MPSAFE). My work resides in truncs_ext2fs branch of Perforce.
Open tasks:

1. Ext4 support for FreeBSD
2. Directory indexing for ext2fs
3. Journaling in ext2fs using gjournal

Come on, it's not that bad.

sycamorex · 07-06-2010, 04:59 AM

Ok, perhaps, another way: what's the best fs for a shared partition between linux and freebsd (rw on both sides)?

Thank you

Unless some exciting breakthrough that I'm not aware of has occurred, the best natively supported format is going to be: (drum roll) - FAT32.

Can anyone pinch me? I think I'm still sleeping. I want to wake up.

Well you could use UDF too

jay73 · 07-13-2010, 12:04 PM

Linux can mount UFS but I'm not sure whether it's RW. I would agree about FAT as the best filesystem for universal sharing (regardless of its many shortcomings).

sycamorex · 07-13-2010, 12:50 PM

I still can't believe it. Isn't it at least slightly ironic that Unix and Linux have to share data via a window's file system? I mean they don't have to, but according to what you guys say, it's the optimal method for rw. Why don't linux and BSD developers work closer to come up with some better solution? Is it something to do with licences?

jay73 · 07-13-2010, 02:13 PM

Possibly. GPL means you HAVE to contribute back, BSD license means you can if you feel like it. No doubt there is a good measure of pragmatism involved, too. Whether you like it or not, FAT is the most widely supported filesystem: Windows, Linux, DOS, Solaris, ... Not to mention all the many devices that use FAT by default.

... and let it stay this way, ALSA/PulseAudio is useless in FreeBSD, its pointless to install it here, everything works flawlessly with OSS.

2. Need to get flash working

Here You go (this works for i386/amd64):

Code:

/etc/rc.conf
  linux_enable="YES"

/etc/fstab
  linproc  /usr/compat/linux/proc  linprocfs  rw  0  0

# kldload linux
# pkg_add -r linux_base-f10
# pkg_add -r nspluginwrapper
# pkg_add -r firefox35
# pkg_add -r linux-f10-nspr
# pkg_add -r linux-f10-sqlite3
# pkg_add -r linux-f10-curl
# pkg_add -r linux-f10-libssh2
# pkg_add -r linux-f10-nss
# mount linproc
# /etc/rc.d/abi restart
# /etc/rc.d/sysctl restart
# cd /usr/ports/www/linux-f10-flashplugin10 && make install clean

% find / -name libflashplayer.so
    /usr/local/lib/npapi/linux-f10-flashplugin/libflashplayer.so

% nspluginwrapper -v -i /usr/local/lib/npapi/linux-f10-flashplugin/libflashplayer.so

(sometimes also needed)

% mkdir -p ~/.mozilla/plugins

% cp /usr/local/lib/npapi/linux-f10-flashplugin/libflashplayer.so ~/.mozilla/plugins

3. Need to find out which sound module needs to be loaded. At the moment I load a meta one.

You can figure it like that, for me its snd_hda:

Code:

% cat /dev/sndstat 
FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <HDA Realtek ALC888 PCM #0 Analog> at cad 0 nid 1 on hdac0 kld snd_hda [MPSAFE] (1p:1v/1r:1v channels duplex default)
pcm1: <HDA Realtek ALC888 PCM #1 Analog> at cad 0 nid 1 on hdac0 kld snd_hda [MPSAFE] (1p:1v/1r:1v channels duplex)
pcm2: <HDA Realtek ALC888 PCM #2 Digital> at cad 0 nid 1 on hdac0 kld snd_hda [MPSAFE] (1p:1v/0r:0v channels simplex)

There is only R/W support for ext2 and ext3 (mounted as ext2 = without journal).

Does Linux support R/W on FreeBSD's UFS? (I know its not, so do not expect FreeBSD to support every Linux centric filesystem out there)

sycamorex · 07-14-2010, 04:48 PM

Thanks for a useful reply, however, I've already configured most of the things I wanted.

The only problem is that it crashes quite often. Everything freezes and that's it. I don't spend much time on FreeBSD, but I'll look at the logs in the near future
to sort it out - it's probably the video driver.
I doubt I'll become my 'main' desktop but I got to like FreeBSD a lot.

You make it sound as if there was some great animosity between the two systems. I don't know much about *BSD history but I assume that there isn't any.
I'm not saying that it's down to BSD devs to develop a better support for linux file systems. It can be the other way round. I'd expect a higher degree of
cooperation between the two systems from both sides.

Strange, it does not crash for me, I have 60+ days of uptime on workstation/server ...

What hardware You have (motherboard + graphics most important info).

Also what is your output of vmstat -i

I just saw too many people yelling about that FreeBSD SHOULD support it because Linux supports it, I see that You are more knowledgeable person and know how things are.

Also, FreeBSD supports fuse so all filesystems that use fuse will work under FreeBSD.

So that does not work:?

I guess i have to try.

It has everything to do with licenses.
