SUSE® Linux Enterprise was the first enterprise Linux distribution to support journaling filesystems and logical volume managers back in 2000. Today, we have customers running XFS and ReiserFS with more than 8TiB
in one filesystem, and the SUSE Linux Enterprise engineering team is using our 3 major Linux journaling filesystems for all their servers. We are excited to add the OCFS2 cluster filesystem to the range of supported
filesystems in SUSE Linux Enterprise. For large-scale filesystems, for example for file serving (e.g., with with Samba, NFS, etc.), we recommend using XFS. (In this table "+" means "available/supported"; "-" is
"unsupported")
[1] The maximum f ile size abov e can be larger than the f ilesy stem's actual size due to usage of sparse blocks. It should also be noted that unless a f ilesy stem comes with large f ile support (LFS), the maximum f ile
size on a 32-bit sy stem is 2 GB (231 by tes). Currently all of our standard filesy stems (including ext3 and ReiserFS) hav e LFS, which giv es a maximum f ile size of 263 by tes in theory. The numbers giv en in the
abov e tables assume that the f ilesy stems are using 4 KiB block size. When using dif f erent block sizes, the results are dif f erent, but 4 KiB ref lects the most common standard.
[3] Btrfs is a copy-on-write logging-style file system, so rather than needing to journal changes before writing them in-place, it writes them in a new location, and then links it in. Until the last
write, the new changes are not “committed.”
[4] Btrfs quotas will operate differently than traditional quotas. The quotas will be per-subvolume rather than operating on the entire filesystem at the user/group level. They can be made
functionally equivalent by creating a subvolume per- user or group.
