GlusterFSで 0-nfs: readv on XX.socket failed が出まくる問題の対応

GlsuterFSのNFS機能を使ってないのに /var/log/glusterfs/etc-glusterfs-glusterd.vol.log に↓こんなログが大量に出ていたら。

ボリュームの nfs.disabled を確認して false だったら true に変えてあげましょう。

[root@r17 glusterfs]# gluster volume get vol1 nfs.disable
Option                                  Value
------                                  -----
nfs.disable                             false
[root@r17 glusterfs]# gluster volume set saba2 nfs.disable true
volume set: success
