Hi Jeffrey,
it depends on your Linux version, Oracle DB version and hardware platform, if you ask Oracle.

Oracle MOS is a bit contradictory in that case. Quoting Doc ID 2197176.1:

   "Oracle Database is supported on ext2, ext3 and ext4 file systems (see Note:236826.1 for further information)"

And Doc ID 2196637.1 (Linux on System z):

   "Oracle Database is supported on ext2, ext3, ext4 and xfs file systems"

FWIW, on RHEL or OL7 I still stick to Ext4 after having trouble with sluggish performance having DB files on xfs (using direct i/o).
