[Gluster-users] [volume options] auth.allow fails to resolve hostname

[Jifeng Li]

Hi,

[environment]

1.       gluster version: 3.5.3

2.       os: redhat6.5

3.       volume info shown below:

Volume Name: gv0

Type: Replicate

Volume ID: 37742c27-9f6b-4a38-821f-ea68d1ec8950

Status: Started

Number of Bricks: 1 x 2 = 2

Transport-type: tcp

Bricks:

Brick1: dmf-ha-1-glusterfs:/export/vdb1/brick

Brick2: dmf-ha-2-glusterfs:/export/vdb1/brick

Options Reconfigured:

cluster.server-quorum-type: server

performance.cache-refresh-timeout: 60

performance.io-thread-count: 64

performance.cache-size: 8GB

cluster.eager-lock: ON

auth.allow: dmf-ha-1-glusterfs,dmf-ha-2-glusterfs

nfs.disable: ON

cluster.server-quorum-ratio: 51%

[issue]
When value of auth.allow is set to hostname of the client, one node mount succeeds, one node mount fails.  If auth.allow value is set to the IP address of the client, both nodes mount succeed.

The error log list below:

I also find similar problem described in https://bugzilla.redhat.com/show_bug.cgi?id=915153 . I'm confused why only one node fails . I think if hostname resolving problem, two nodes should fail.
Any tips about debugging further or getting this fixed up would be appreciated.
