[Gluster-devel] getting Input/output error on some files when using tla greater than patch-634

[Mickey Mazarick]

None of the copies were deleted from the backend (we even did a search 
and verify) the strange thing is this doesn't occur on patch-634. We are 
also seeing the same thing on a a afr/stripe/unify (so I'm thinking afr 
is the culprit). once again with the strip/afr/unify example it's only 
some of the files,.

We did try to delete all but one copy directly from the backend servers 
to repair some of the files but the error persisted.

Thanks!
