Can you create a Vxfs or xfs file system on Linux RH9 ???

vxfs doesn't exist for linux. I don't know xfs, but I heard something about the possibility to use it.

I suggest to give a look to reiserfs, it's fast and reliable. It is included in redhat linux.

YES,if you can, I have my linux with JFS and journling:

File Systems available on RedHat Linus:
- VFS
- default ext2fs
- Reiserfs
- JFS

The equivalent of vxfs for Linux is ext3

This is a journaled filesystem with almost the same feature set as vxfs.

You can choose from:

* ext3 - upgrade from ext2 is easy as 1-2-3, but in order to be resized it needs to be downgraded to ext2 and this requires at least an umount, a mount as ext2, resizing, a tune2fs -j to recreate the journal log file and a new ext3 mount. Not recommended when you need to expand an ext3 volume online. ;-)

* ReiserFS - perhaps the most used journaled file system. There is no migration path from ext2, so you'll need to copy files. OTOH, it supports native shrinking and expansion of file systems and both can be done online. Nowadays at version 3, Reiser FS 4 is under active development and will be a revoluctionary product.

* XFS - the journaling file system from SGI. It allows online/offline filesystem expansion, but not shrinking. Very fast. Indicated where you have tons of media files to serve. I use it myself with Linux's LVM and never had any problems, as I have a ton of digitized film scans, each of them with 20+ MB.

* VxFS - contrary to what another poster said, there IS a VxFS for Linux. But it just works with old kernel releases (2.4.9 of RHAS-Enterprise), which have SCSI performance problems. And contrary to the other products listed, it costs $$$$.

So I would go either with ReiserFS (because of versatility) or XFS (high speed for large files). And BTW all of them support 2GB+ file sizes.

I use reiserfs a long with LVM it is already on the main distribution RH, Suse.

I have tryed it on all sort of hardware/setup and have found it to be very robust, it simple to setup and does the jobs, it can be increased, decreased, online, offline.

I have run this on 2 external usb drives, hooked-up to a laptop running RH with LVM and have had no problem to this day.

Also reiserfs developpement is very active.

I have also used ext3 this is also very good, but if you want to use LVM, reiserfs is better.

I have not tryed the other journaling file.
mainly because they are not included with RH

Hello!

By default on RH9 you can't do it but if
you want you can patch the kernel that
will suport this filesystems and also
you will need tools to use this file systems.
Check http://www.linuxhq.com/kernel/file/fs/vxfs/

But for today you have the ext3 that it's
jurnaled filesystem that is good.
Also you kan enable to use the reiserfs
that is very good.
