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 Thanks, Johnny Hughes
