If I run unlink .viminfo I got the same error:
unlink: cannot unlink `.viminfo': Invalid argument
I can't stop the MDS/OSS to do a lfsck or e2fsck because is a filesystem in
production of a lots of terabytes
Any idea more to delete the damm file?
THANKS!

You could just unlink it instead. That will work when rm fails.

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.

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. If you can log on as root, you may
be able to see it clearly.
If that doesn't work, you may have to run an fsck on the MDT (which
may take minutes to hours depending on the size of your MDT)
If that doesn't work, follow the procedure for running an lfsck (which
will take a long time, and require quite a bit of storage to execute)

Hello,
I have a corrupt file than I can’t delete.
This is my file:
ls –la .viminfo
/-? ? ? ? ? ? .viminfo/
/lfs getstripe .viminfo/
/.viminfo/
/lmm_stripe_count: 6/
/lmm_stripe_size: 1048576/
/lmm_layout_gen: 0/
