[lustre-discuss] Stray files after failed lfs_migrate

[Angelos Ching]

Dear all,

I was dealing with some OST migration using lfs_migrate and things went 
mostly fine albeit for a few files that might have been in use during 
the migration:

> # ls
> ls: cannot access ibleTHWm: No such file or directory
> ls: cannot access ib7rP0qy: No such file or directory
> ls: cannot access ib3AQ9vK: No such file or directory
> ls: cannot access ib30N1p9: No such file or directory
> ib30N1p9  ib3AQ9vK  ib7rP0qy  ibleTHWm
> # stat ib30N1p9
> stat: cannot stat ‘ib30N1p9’: No such file or directory
> # lfs getstripe ib30N1p9
> ib30N1p9
> lmm_stripe_count:  1
> lmm_stripe_size:   1048576
> lmm_pattern:       raid0
> lmm_layout_gen:    0
> lmm_stripe_offset: 1
>     obdidx         objid         objid         group
>          1          71909438        0x449403e 0
The files couldn't be stat'ed but still returns upon lfs getstripe.

The same error appears on all clients and I've tried unmounting and 
remounting the MDT on the server side already.

Any idea what might have been corrupted and what could be the fix?

Cheers,
