[Gluster-users] Initial mount problem - all subvolumes are down

Mon Mar 30 23:11:09 UTC 2015

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:*

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.
