If not: http://oss.sgi.com/projects/xfs/faq.html#dir2 That shouldn't be affected by volume size. Raz, are you certain that the MD volume is in good shape at this point, after Neil's questions? If it's something you can test on, I'd suggest getting lmdd and writing a pattern directly to the block device, spanning the 8T point, then go read it back & double check that all is well. XFS certainly has been tested at 8T and above; if I had to bet on it, I'd bet at a problem in another layer, or the configuration. -Eric
