What i'm planning to do is this. 1 server with a dualboot with Gentoo and FreeBSD. With a partition (/srv) for the files the server will be serving. But both installations must be able to read/write to that partition. I prefer using reiserfs .. but FreeBSD has no such support. Some guy's told me to use FAT32 (why use linux/unix to use a old windows filesystem) or ext2 (quite old and not robust, not?).
So my question is .. what choise do i have in filesystems to fit my needs?

Thx!

according to this page, you can mount ext2 and ext3 filesystems from freebsd. Journaling will just not work if you use ext3.

ext2 is just the same as 3 but just without journaling .. so it's not too depreciated.

Thx for ur reply auximini .. that's a very intresting doc! But i had some bad things happen with ext2 and 3 .. afther a power down the whole partition wasn't writable anymore .. so the os couldn't boot etc .. a f*** up thing. So i'm looking for alternative's .. a worthy file system like reiserfs .. and i also prefer a journaling filesystem.

Can't i for example use a FreeBSD file system that also Gentoo reads/writes .. ?
Isn't exfs or extfs a good idea?

Last time I used FreeBSD, it used the UFS filesystem. Linux supports UFS, but in 2.6.6, I believe it was read only. That might have changed, so I would check on that, too.

So that way is possible, too.

As for the Reiser FS, last time I heard, it only had read-only support. That might have changed as well.

As far as I remember, you have to be careful about choosing the right UFS system. I think Linux can make use of UFS(1), but cannot handle UFS2. The latter is the preferred partition type in the FreeBSD 5.x series I think, you will probably have to change the given choice in the installation process of FreeBSD.

If you decide to use UFS, you first got to know that FreeBSD 5.x by default comes with UFS2 ! So you have to install FreeBSD with UFS. Than you have to use 2.6 kernel on the gentoo (2.6.11 is fine) it can handle UFS read/write but it's "DANGEROUS".
And btw do NOT use FAT filesystem for any kind of server!! First because FAT doesn't know what is that thing owner, group, premission etc and you are unable to download files stored in FAT filesystem via HTTP/FTP server, second FAT isn't journal filesystem and it can crash at any time.

I don't get this. I transfer a lot of files on my home network stored on FAT. (FAT32 anyways..)

Hmm...
I think that this is only possible if you use pure web server (without .htaccess)
so that the server doesn't care about the owner/permission and maybe anonymous FTP... otherwise I can't see how can you download files from FAT filesystem.
I always use .htaccess and when I tried FAT to store my files I experienced that noone can download.

Thx for the reply's guy's!
I want to use UFS2 but i want the be shure there will nothing hapen with my data so maybe that isn't also a solution.
Maybe i should just learn first BSD on another server first and then install it on that server an convert the /srv partition to a BSD partition (whyle the data is stored elswere). I searched a lot on the net but didn't find a good solution, so I'll do that.

Many thx!
