Ext3 users - Oct 2002 - to compare journalised file systems with Linux.

Lo,

Actualy i'm looking for documents about journalised file system, in 
order to be able to compare them self. I need accurate information if i 
want to make a good study.

Thoses informations have to permit me to get answer about table like this :

  Features \ fs    | xfs | ext3 | jfs | reiserfs |
-------------------------------------------------
chattr            |  ?  |  Y   |  ?  |    ?     |
-------------------------------------------------
quotas            |  Y  |  ?   |  Y  |    ?     |
-------------------------------------------------
removable fs      |  ?  |  ?   |  N  |    ?     |
-------------------------------------------------
NFS               |  Y  |  Y   |  ?  |    ?     |
-------------------------------------------------
samba             |  ?  |  ?   |  ?  |    ?     |
-------------------------------------------------
coda              |  ?  |  ?   |  ?  |    ?     |
-------------------------------------------------
...

My line is to remove all '?' by 'Y' or 'N' for all my
table.

I know thoses links talking about ext3 :
http://beta.redhat.com/index.cgi?action=ext3
http://bulmalug.net/body.phtml?nIdNoticia=1154

but a need more accurates informations.

I know bonnie++ as disk tool tester, but i would like to have several 
points of view with several tools.

If you know some others links or books or good tools, you are wellcom.

Thanks Fabien.

ext3 does quotas

ext3 can be used on floppies (for example).

ext3 can be used as a basis for NFS.

ext3 can be used as a basis for samba.

ext3 is "Y" to all the above except for coda.  Coda is an entire
filesystem all to itself: it does not run on top of another
filesystem.  So, Coda support is "N" for all filesystems except for
Coda.  :-)  InterMezzo, on the other hand, can use ext3 as its cache
filesystem.

Also be aware that ext3's default journaling mode is more conservative
than most other filesystems', and that it provides ordering guarantees
for data as well as metadata, which hurts it in some benchmarks.  You
can mount with "-o data=writeback" to fall back to unordered data
writes.
