[ale] XFS the default in RHEL 7?

[Lightner, Jeff]

As I said ext4 is supported fully as of RHEL5.4.

It does have performance benefits over ext3.   Not the least of which is you don't have to wait 3 days for the full fsck to finish on your 6 TB filesystem.

I've been using XFS for the better part of a decade...  especially after the ReiserFS (MurderFS?) implosion.  We are about 95% SUSE, with a few RHEL and CentOS servers around because of vendor requirements.  Ext3 has been showing its age for a long time, and I was hoping that ext4 would bring about something better, but not really.  The SUSE guys (not OpenSUSE) have been very opposed to ext4, to the point that you can't even create an ext4 filesystem, and you have to load an extra package to enable read only support for it.
I find it annoying that even after implementing support for XFS (although it is a paid add-on), you still can't make "/" XFS on RHEL.  I've been experimenting with BtrFS, but not on anything production.
I still haven't found anything that has given better results than XFS for our use.

ext4 has some nasty bugs that block use of filesystems larger than 40-something TB. Ext4 SUPPORTS massively larger filesystems that 40TB but due to an implementation bug (that isn't getting fixed for some reason) it's stuck. I recently setup a 56TB drive array and XFS was perfectly happy. EXT4 just choked. Tested with a Fedora 18 and a rawhide just to see WTF and yep, even Debian has the issue.

So XFS will handle exabytes. So will ext4 eventually.
