| 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.

As someone who is working with 15-30TB volumes, use XFS, but be sure you have a lot of memory. 48GB at least and more if you have directories with 10s of thousands of files in them.
