[Lustre-discuss] delete a "undeletable" file

[Ben Evans]

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.  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)

Subject: [Lustre-discuss] delete a "undeletable" file

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
lmm_stripe_offset:  18
        obdidx           objid          objid            group

            20              50           0x32                0

And these are my OST:
