+++ This bug was initially created as a clone of Bug #1294446 +++ +++ +++ +++ Use this bug to backport the fix to release 3.7. +++ Description of problem: When rpcbind is not running on the server (or is firewalled), and a Gluster volume is started (after create or stop), a hook script calls 'showmount' and hangs. Version-Release number of selected component (if applicable): current master How reproducible: 100% Steps to Reproduce (from memory): 1. stop the rpcbind service (also rpcbind.sock on systemd based installations) 2. create a volume 3. set the 'ganesha.enable' volume option 4. start the volume Actual results: The 'gluster volume star ...' command hangs, Expected results: No hang. Additional info: The cause seems to be the 'S31ganesha-start.sh' hook script. Instead of 'showmount', an equivalent dbus command could be used. --- Additional comment from Vijay Bellur on 2015-12-28 10:40:26 CET --- REVIEW: http://review.gluster.org/13098 (scripts: prevent running 'showmount' from the start/post hook script) posted (#1) for review on master by Niels de Vos (ndevos) --- Additional comment from Niels de Vos on 2015-12-28 10:54:58 CET --- (In reply to Niels de Vos from comment #0) ... > Steps to Reproduce (from memory): > 1. stop the rpcbind service (also rpcbind.sock on systemd based > installations) > 2. create a volume > 3. set the 'ganesha.enable' volume option > 4. start the volume It does not seem to be required to set the 'ganesha.enable' volume option. The 'showmount' command that hangs, is executed before this option is checked. --- Additional comment from Vijay Bellur on 2016-01-12 16:38:35 CET --- COMMIT: http://review.gluster.org/13098 committed in master by Kaleb KEITHLEY (kkeithle) ------ commit 2b2294d2a4ef221fccb6eb9f74e9b7dc233b9f1d Author: Niels de Vos <ndevos> Date: Mon Dec 28 10:26:20 2015 +0100 scripts: prevent running 'showmount' from the start/post hook script The 31ganesha-start.sh hook script tries to run 'showmount' to see if the volume that is getting started should get exported by NFS-Ganesha. It was reported that this caused the 'gluster volume start ...' command to hang in case rpcbind is not running. Instead of running 'showmount', we can use DBus to contact NFS-Ganesha directly, and request the available exports. This will immediately fail in case NFS-Ganesha is not running.
