[Gluster-users] Access to Servers hangs after stop one server...
I think your mount statement in /etc/fstab is only referencing ONE of the gluster servers. Please take a look at "More redundant mount" section: https://www.jamescoyle.net/how-to/439-mount-a-glusterfs-volume Then try taking down one of the gluster servers and report back results.

I have followed the very same instruction that found in the James's website. One of method his mentioned in that website, is create a file into /etc/glusterfs directory, named datastore.vol, for instance, with this content: volume remote1 type protocol/client option transport-type tcp option remote-host server1 option remote-subvolume /data/storage end-volume volume remote2 type protocol/client option transport-type tcp option remote-host server2 option remote-subvolume /data/storage end-volume volume remote3 type protocol/client option transport-type tcp option remote-host server3 option remote-subvolume /data/storage end-volume volume replicate type cluster/replicate subvolumes remote1 remote2 remote3 end-volume volume writebehind type performance/write-behind option window-size 1MB subvolumes replicate end-volume volume cache type performance/io-cache option cache-size 512MB subvolumes writebehind end-volume and then include this line into fstab: /etc/glusterfs/datastore.vol [MOUNT] glusterfs rw,allow_other, default_permissions,max_read=131072 0 0 What I doing wrong???
