See docs/authentication.txt for more details. - -* To copy the data served by httpd into glusterfs mountpoint, glusterfs can be started with the - volume-specification file provided to mod_glusterfs.

If not on Linux gdb runs into errors like: - "Error while reading shared library symbols: - Cannot find new threads: generic error" - -* when used with ib-verbs transport, ib_verbs initialization fails. - reason for this is that apache runs as non-privileged user and the amount of memory that can be - locked by default is not sufficient for ib-verbs. to fix this, as root run, - - # ulimit -l unlimited - - and then start apache. diff --git a/mod_glusterfs/apache/2.2/src/mod_glusterfs.c b/mod_glusterfs/apache/2.2/src/mod_glusterfs.c deleted file mode 100644 index d2b9f323266..00000000000 --- a/mod_glusterfs/apache/2.2/src/mod_glusterfs.c +++ /dev/null @@ -1,3627 +0,0 @@ -/* - Copyright (c) 2008-2011 Gluster, Inc. <http://www.gluster.com> - This file is part of GlusterFS. - - GlusterFS is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published - by the Free Software Foundation; either version 3 of the License, - or (at your option) any later version. - - GlusterFS is distributed in the hope that it will be useful, but - WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
