We have a case of a server that did not write anything at the time of failure (and during all the uptime session). Moreover, failure occurs to files that were opened in read-only or weren't accessed at all at the time of failure. I don't think the H/W RAID is the issue since we have the same corruption with other setup without H/W RAID. Does the "ls" output with "???" looks like a fs corruption ? _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
