[CentOS] 11TB ext4 filesystem - filesystem alternatives?

Hi All.

I have a CentOS server:

CentOS 5.6 x86_64 2.6.18-238.12.1.el5.centos.plus e4fsprogs-1.41.12-2.el5.x86_64

which has a 11TB ext4 filesystem. I have problems with running fsck on it and would like to change the filesystem because I do not like the possibility of running long fsck on it, it's a production machine. Also I have some problems with running fsck (not enough RAM, problem with scratch_files option) and if the filesystem will need intervention I will be in a problematic situation.

Which other mature and stable filesystem can you recommend for such large storage?

Best regards, Rafal Radecki.
