gluster volume create volume01 replica 2 transport tcp server01:/brick01
server02:/brick01
gluster volume start volume01
Then server1 and server2 each mount the volume from themselves via
/etc/fstab entry:
localhost:/volume01 /glusterfs/vol01 glusterfs
defaults,_netdev,acl 0 0
This works, modifications inside /glusterfs/vol01 are seen by the other
host. However when I reboot either server01 or server02, the client mount
point on the surviving node (/glusterfs/vol01) hangs until the node
reboots. If the node never boots, the client mount point on the surviving
node hangs for 30 minutes. I have tried reducing frame-timeout to 10
seconds to no avail.
Also; once the rebooted server comes back online it fails to mount
/glusterfs/vol01, hanging, again for 30 minutes. A subsequent remount
succeeds. Cancelling the hung mount with umount -f /glusterfs/vol01 and
then re-mounting succeeds.
Any ideas what I am doing wrong?

glusterfs 3.2.4 to a pair of Red Hat Enterprise Linux 6.1 x86_64

of content between the two servers, which also serve and update the

mount points hang for 30 minutes or so if either node is brought
down.<br><br>The volfile will be at the end of this e-mail.<br><br>I
setup two bricks, one each on nodes server01 and server02, using ext4
