RE: mounting UFS under Linux

2005-09-18 Thread Christopher Martin
Sort of the wrong forum for you question.

If you are looking for information about a Gentoo you are better off asking
in a Gentoo forum, but I will try and help, none the less.

http://www.tldp.org/HOWTO/Linux+FreeBSD-5.html seems to suggest that you
must recompile the Kernel, however like a lot of documentation in the Linux
world it's out of data, referring to kernel 2.0, so I don't know how
relevant it is. You may just need to load an already compiled module, for
all I know.

Also, be aware that FreeBSD has kept the soft-updates file table method,
rather than move to a journalled file system. If you are interested in a
comparison, have a look at:
http://www.usenix.org/publications/library/proceedings/usenix2000/general/fu
ll_papers/seltzer/seltzer_html/index.html

It's an older document but, still holds true in most cases.

Lastly, if you like Gentoo I am willing to bet you would like FreeBSD. Take
a look, you might find you like it, and the performance benefits are worth
it. FreeBSD 6 will see serious performance improvements, building on
FreeBSD's already amazing performance, and with contextual locking, ACLs and
totally asynchronous I/O it should make for some amazing performance. Beta 4
is out now, and it will be in full release before the end of the year.

Hope that helps.

Ask your Linux support question on a Linux support list ;-)

I'd start by asking a Linux mailing list, I guess gentoo as that is the OS 
you need support for.

IIRC, 2.6 kernel supports mounting of UFS. Was able to do so with
Knoppix livecd with 2.6. Don't know what to do in case of 2.4 though.
Don't remember the exact thing righht now, but you can find details in
manual page of man. Look for ufs and ufstype (44bsd).

Hi Jan,

>From the release notes:

 newfs(8) will now create UFS2 file systems by default, unless UFS1 is
 specifically requested with the -O1 option.

I would be surprised if linux understands UFS2 allready.

Re: ufs problem (mounting ufs under linux-2.6.0-test11)

2003-12-11 Thread Jan . Stary
Hello,

I don't seem to be able to mount the FreeBSD-5.1-RELEASE's ufs
partition in linux-2.6.0-test11, which occupies another partition
on the same machine (which is Acer Aspire 1304XC).

Has the ufs format changed in 5.1? I specify ufstype=44bsd in
the mount command.

Thank you

Jan

:"ufs_read_super: bad_magic_number" is a very odd behaviour :-(

Yes. I am using the partition for my BSD boots happily, though -
maybe the ufs has changed in freebsd 5.1 ? I will ask on the BSD
list.

Thanks for your time, Heiko.
