hi all,
this is a wild idea...suggestion...
i wanted to ask if there were any _plans_ to port
JFS (Journaled File System) to FreeBSD...
as for JFS, it is developed by IBM for Linux and
is licensed under GPL, so we could put this into
src/gnu/
It is used on IBM MainFrames and Enterprise servers

Hi Hiten,
Search the mail list archives (from www.freebsd.org) for JFS and XFS.

I'm no expert on journaled filesystems, but isn't the freebsd softupdates
option similar? perhaps there could be an upgrade to offer
options SOFTERUPDATES
as an equal-but-different alternative to jfs?

Not unless you have plans. When I was an IBM employee, they would
not change the license, and so it's impossible to ship a CDROM
where it's the boot FS, or boxes on which it is the

hi,
BTW, i am a first timer at porting a file system...
if the proffesionals think that it is not wise or
useful to port the FS (especially IBM's), it is OK,
but, just in case, anyone else (more than three
people)
would like to port this FS to FreeBSD, my target would
be to get it done by Septe

I think I would rather see people tweaking the heck out of the existing UFS
filesystem and implementing new ways of getting it to go faster.
Implementing a whole new filesystem would probably take a lot of work, and
the performance wouldn't be much better anyways. IMHO, people interested in

That is okay, few programmers ever port more than one file system.
Most useful is to have some experience programming and debugging FreeBSD
kernel code.

Hi,
as i said also before, my intentions were never to
cause havoc on the mailing list. :-)
In simple terms, what i am saying is, the people who
would like to port the JFS file system, should put a
+1 in their next message and -1 if they dont like to
port JFS.
Then, i will count the votes, an
