Hi Phil,
I think that's from the crdirent, which does a keyval_read to
verify that the directory doesn't exist, and only creates it if
ENOENT is returned. At the level of keyval_read_op_svc, its
impossible to know that though. I guess I can just remove the
error reporting call, although it would be nice to have it there
for cases where we actually want to read an entry we expect to be
there and print an error if we don't find one (corrupted db).
Actually I take that back. The only place in the keyval.c code we
print an error is in read_list. So it probably isn't a problem there
since read_list is only used by get_eattr. So the keyval_read_op_svc
only prints a warning if DBPF_KEYVAL_DEBUG is enabled.
It looks like the error you're seeing might be in dspace_getattr,
which gets called from lookup and prelude. If we do a lookup to
verify that a file doesn't exist before creating it , I could imagine
seeing that. In any case the problem is the same as before. I could
print a warning if debugging is enabled.
Alternatively, I could create a trove flag (TROVE_NOENT_NON_FATAL)
for those operations where we actually want to return ENOENT as a non-
fatal response.

If I start a pvfs2-server in the foreground (with the -d option),
I see quite a few of these messages on the console when accessing
the file system, even with just an ls:
pvfs2-trove-dbpf: DB->get: DB_NOTFOUND: No matching key/data pair
found
I assume this isn't really an error; trove was probably just asked
to look up something that was expected to not exist. Should this
message be quieted?
