There is a 1-line patch that can be applied : http://marc.theaimsgroup.com/?l=linux-kernel&m=115315508506996&w=2 FAQ message here http://marc.theaimsgroup.com/?l=linux-xfs&m=115338022506482&w=2 FAQ: http://oss.sgi.com/projects/xfs/faq.html#dir2 It appears that efforts are being focused on the repair tools now. It appears to me that the best response is to patch the kernel, reboot, backup the fs, recreate the fs and restore - but please read up before taking any action. David --
