Right now all tests have failed. OS in Centos 5.4 x86 PAE so I opened a ticket both in Centos and Redhat bugzilla. I don't have any contract with redhat but I hope they will give a try on this. https://bugzilla.redhat.com/show_bug.cgi?id=573185 http://bugs.centos.org/view.php?id=4239 My feelings are that it has to do with the software raid layer and not the filesystem (ext4, xfs, gfs all died). The filesystem seems to not get the appropriate physical/logical quandaries from the raid layer. Unless the x86 kernel is not capable of addressing large filesystems as it is documented (16TB as you said). best regards, Giannis
