Does a /etc/passwd with all the filesystem users UID's required only on the MDS ? Or does the OST's need them also? Testing for me shows only the MDS, but I could be wrong. We don't use LDAP or anything like that at the moment for UID GID mapping. Brock Palen www.umich.edu/~brockp Center for Advanced Computing brockp at umich.edu (734)936-1985
