Gluster users - Mar 2014 - deleted files directly in distribute brick

In a moment of insanity I deleted a few hundred files in a gluster brick
(30TB of 133TB) which is part of a distribute volume. I want these files
deleted. but did not do it through the client. The volume is reporting a
size as if they are still there. The files in .glusterfs are still there
and I don't know which ones to delete.

I think the data was linked from the primary directories and the .glusterfs
directories and when I deleted the files from the primary directories the
data did not delete because of the links in .glusterfs.

Is it survivable to delete all of .glusterfs in one or all bricks and hope
that gluster will repair it?

Since the files in .glusterfs are hard links, your data isn't actually
gone-- you could restore the lost data in fact if you were able to
determine the names of the files that were deleted based on the contents of
the hard links in the .glusterfs directory.  Big "if" but we're
talking
about recovering data, so it's up to you.  If practicable, it's smart to
keep a list of inode-filepath associations somewhere, but this probably
doesn't help now.

You can use find(1) to locate which of the .glusterfs files references one
of the deleted files on the brick:
find /path/to/.glusterfs -links 1 -ls
