+++ This bug was initially created as a clone of Bug #996511 +++ Description of problem: We are suggesting (documenting) customers to set "server.allow-insecure on" for samba/smb share access from RHS servers. But if i list the help of gluster volume set i.e. "gluster volume set help" it is not there. However I can run the command successfully. Check the below commands and their output #gluster volume set server.allow-insecure on [root@rhs21ISoTest samba]# gluster volume info Volume Name: gfs-vol1 Type: Distribute Volume ID: 887dc3fe-5f93-4d45-85c9-91a714114de2 Status: Started Number of Bricks: 2 Transport-type: tcp Bricks: Brick1: 10.70.35.220:/bricks/gfs-vol1-b1 Brick2: 10.70.35.220:/bricks/gfs-vol1-b2 Options Reconfigured: performance.stat-prefetch: off server.allow-insecure: on I checked the code found that the volume set option "server.allow-insecure" is defined as "NO_DOC" type, which needs to be changed to fix the issue. xlators/mgmt/glusterd/src/glusterd-volume-set.c { .key = "server.allow-insecure", .voltype = "protocol/server", .option = "rpc-auth-allow-insecure", .type = NO_DOC, .op_version = 1 }, Version-Release number of selected component (if applicable): glusterfs-server-3.4.0.17rhs-1.el6rhs.x86_64 How reproducible: always Steps to Reproduce: 1. run gluster volume set help 2. check if help for "server.allow-insecure " is present Actual results: "server.allow-insecure " is not present in "gluster volume set help" Expected results: "server.allow-insecure " should be present in "gluster volume set help" Additional info: --- Additional comment from Christopher R.

If the user does not enable server.allow-insecure, Samba (via vfs_glusterfs and libgfapi) will run out of available ports and fail to connect to the Gluster server daemon. This will cause the SMB clients to fail to connect to the server with only an error message in the Samba logs. See bug #981612. This setting must be documented and available to users. --- Additional comment from Vivek Agarwal on 2015-12-03 12:23:20 EST --- Thank you for submitting this issue for consideration in Red Hat Gluster Storage.
