I have worked very hard to get stable code for xfs in centos-4 and
centos-5, and lots of people use it, but (IMHO) ext3 is still much more
stable with the CentOS Kernels.
That is my $0.02 ... I'm sure other people will tell you I am all hosed
up :D
EXT3 performance is lacking in many areas and its support for larger
file systems is still a problem. However, it is rock solid and
hopefully EXT4 will address the performance and file system limit issues.
I don't disagree with that assessment, however newer versions of ext3
have switches to use to improve performance and they work on bigger file
systems.
Still, ext3 support is indeed lacking on larger filesystems and yes,
hopefully ext4 will address this.
But ... still, if spending a fortune on HUGE drives for an enterprise
file system I would still think that one should at least see if ext3
will meet their needs before automatically shifting to XFS. I have seen
many a filesystem be unrecoverable with XFS, especially on 4K stack
systems (which CentOS i386 is).
Believe me, I have personally put a lot of time and effort into the xfs
filesystem modules that are in CentOS Plus and CentOS Extras ... and I
use them in some places, but I just want to be on record saying that
ext3 is more stable and I recommend its use unless it just
_WILL_NOT_WORK_, that's all :D

I am not an expert in filesystems.
But, yes, in all these years on Linux, i have never found ext3 go bad
for me ever.
Infact, i have never tried any other fs till date.
Going by the comments and views of everyone, i would prefer to go with ext3.
The drive is a large one, but i have no particular need to make one big
partition on it.
I can as well have several small partitions (in fact thats what i want)
with each partition being the data store for 1 mogstored daemon.
Now i am not sure if thats the best possible solution, but i still got
time to implement it and do my benchmarks.
For now, ext3 is surely the fs of choice. Cannot afford to lose anything
thats going to be stored on this server.
A big thanks to everyone.

A.S
