Statements like this do not give me the warm fuzzies.  Is Gluster safe
to use in a production environment?

Noted.  I will do the same then.

This particular file, yes.  I can open with tar -ztvf and see it's
contents just fine.  However I have found other problems.

One of the files listed by heal-failed is:

2013-07-11 16:07:53
/BACKUPS/2013-07-10/origo/export/a/home/flagon/src/matlab-r2012a/config/matlab-r2012a/opt/matlab-r2012a/toolbox/signal/signal/@dspdata/@groupdelay/schema.p

When I try to access the file, I get:

# ls -ald
/BACKUPS/2013-07-10/origo/export/a/home/flagon/src/matlab-r2012a/config/matlab-r2012a/opt/matlab-r2012a/toolbox/signal/signal/@dspdata/@groupdelay/schema.p
ls: cannot access

No such file or directory

Both of the above files are listed as having been healed.  The first one
is available, the second one returns an error.

Correct.
