Something about the ubuntu upgrade messed with your disk. I'd press them very hard to investigate & resolve that. You can probably use hdparm to remove the HPA and get your space back but this is beyond my expertise & familiarity. It'd be interesting to know what is _in_ the HPA area first. -Eric _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
