Hi, If the file is disassociated with an OST which is offline, bring the OST back online, if the OST object it self is missing then you can remove the file using 'unlink' rather than 'rm' to unlink the object meta data.
If you want to try and recover the missing OST object an lfs getstripe against the file should yield the the OST on which it resides. Once that's determined you can take that OST offline and e2fsck may successfully restore it. Another option as Ben correctly points out, lfsck will correct / prune this meta data as well as the now orphaned (if any) OST object. -cf On 03/07/2013 08:30 AM, Ben Evans wrote: > The snarky reply would be to use Emacs. > > More seriously: > > When I see something like ?????? in the attributes for a file, my > first thought is that the group_upcall on the filesystem is not > correct, so permissions are broken.
