Atin,
Could it be because bricks are started with PROC_START_NO_WAIT?
That's the correct analysis Pranith. Mount was attempted before the
bricks were started. If we can have a time lag in some seconds between
mount and volume start the problem will go away.
Atin,
I think one way to solve this issue is to start the bricks with
NO_WAIT so that we can handle pmap-signin but wait for the pmap-signins
to complete before responding to cli/completing 'init'?

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.

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.
