See https://ext4.wiki.kernel.org/index.php/Ext4_Howto#Bigger_File_System_and_File_Sizes The ext4 filesystem itself has 48-bit block addressing but the e2fsprogs does not => Unfortunately there still is a 16 TB filesystem limit. I've verified this myself with 5.4 by trying to create a 24 TB filesystem. This did not work but creating a 16 TB filesystem did. Regarding ext4: Maybe you're also interested in this ext4 sync bug on large memory systems present in both 5.4 and 5.5: https://bugzilla.redhat.com/show_bug.cgi?id=572930 XFS has its problems on RHEL, too. See e.g. http://www.bofh-hunter.com/2009/09/04/rhel-5-4-and-xfs/ Karsten PS: IMHO the by far the best working solution for huge filesystems is ZFS which unfortunately is not available for the Linux kernel... btrfs? We'll see. -- __________________________________________creating IT solutions Dipl.-Inf.
