He's hosed. If this had been a grow from 8 disks to 10 he'd be ok, as you grow mdadm first then XFS. But as I said, XFS has no shrink capability. xfs_repair will just puke all over itself if you run it. > Maybe you could ask on an XFS list somewhere. He already did, in a way, as I'm on that list. You're more than welcome to ask on the XFS mailing list, but you'll get the same answer. This really sucks and I feel for Matt. I wish he'd have asked on either or both lists first... What he needs to do now is start over from scratch. Delete the current md device and create a new one, then create a new XFS filesystem, and then restore his files from his backup device. Is there a Linux mdraid best practices document somewhere, that could help prevent folks from hosing themselves like this if they'd read it first? -- Stan -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
