Hello everyone,
I have a problem that I am trying to resolve and not sure which way to go so here I am asking for your advise.
What it comes down to is that upon initial boot of all my GlusterFS machines the shared volume doesn't get mounted. Nevertheless the volume successfully created and started and further attempts to mount it manually succeed. I suspect what's happening is that gluster processes/bricks/etc haven't fully started at the time the /etc/fstab entry is read and the initial mount attempt is being made. Again, by the time I log in and run a mount -a -- the volume mounts without any issues.
Details from the logs:

Volume configuration is:

Number of Bricks: 1 x 3 = 3
Transport-type: tcp
Bricks:

Brick3: host3:/opt/local/brick
Options Reconfigured:
storage.health-check-interval: 5

cluster.quorum-type: auto
network.frame-timeout: 60
I run Debian 7 and the following GlusterFS version 3.6.2-2.
While I could together some rc.local type of script which retries to mount the volume for a while until it succeeds or times out I was wondering if there's a better way to solve this problem?
Thank you for your help.
