[Gluster-users] Gluster volume not automounted when peer is down

This is interesting, I think this is the same problem as mine.

Quoting myself from 1st message:
If I shutdown one of the servers (, and I reboot the
remaining one (, it won't come up as fast as it should. It
lags a few minutes waiting for gluster. After it eventually starts,
mount point is not mounted and volume is stopped:
This didn't happen before, so fine, I first have to stop the volume and
then start it again. It now shows as online:
Brick                           49155 Y       3473
Self-heal Daemon on localhost                           N/A Y       3507

# time mount -a
real    2m7.307s

# time mount -t glusterfs /var/www/hawaii
real    2m7.365s
Quoting myself from 2nd message:
Steps to reproduce:
1. probe server2, create and start volume
2. do not mount volume
3. reboot/poweroff server2; or add server1 to its iptables (with -j
DROP, not -j REJECT)
4. on server1 (while server2 is rebooting or dropping traffic from
server1): time mount -t glusterfs server1:/volume /some/path

PS: with -j REJECT it mounts instantly. with -j DROP it always waits
2mins 7secs

Can you also take a look and confirm it is the same? Also, while keeping one node down, please try that "time mount" command.

Hi all,

We're trying to use gluster as a replicated volume.  It works OK when both peers are up but when one peer is down and the other reboots, the "surviving" peer does not automount glusterfs.  Furthermore, after the boot sequence is complete, it can be mounted without issue.  It automounts fine when the peer is up during startup.  I tried to google this and while I found some similar issues, I haven't found any solutions to my problem.  Any insight would be appreciated.  Thanks.

gluster volume info output (after startup):
Volume Name: rel-vol
Type: Replicate
Volume ID: 90cbe313-e9f9-42d9-a947-802315ab72b0
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp

gluster peer status output (after startup):
Number of Peers: 1

Uuid: 8d49b929-4660-4b1e-821b-bfcd6291f516
State: Peer in Cluster (Disconnected)

Original volume create command:
gluster volume create rel-vol rep 2 transport tcp

I am running Gluster 3.4.5 on OpenSuSE 12.2.

This is shorter than it is when it works, but maybe that's because the mount spawns some more processes.

Some ports are down:
