[Gluster-users] one node gluster fs, volumes come up "N/A"

[Jarosław Prokopowski]

Hello,
I'm new here. I tried to google the answer but was not successful.
To give it a try I configured one node Gluster FS with 2 volumes on CentOS
7.5.1804. After server reboot the volumes start but are offline. Is there a
way to fix that so they are online after reboot?


#gluster volume status
Status of volume: os_images
Gluster process TCP Port RDMA Port Online Pid

After running:
gluster volume start <volume_name> force
the volumes become Online.

Upon server reboot, glusterd has the responsibility of re-starting bricks
for started volumes.Checking the brick & glusterd log files can help in
determining why the bricks did not start up.

Yes,

It looks like network.service fails and the glusterd.service is set up to
start after network.service. In my case networking is set up by
NetworkManager.service that starts later.
There is no dependency on NetworkManager.service in glusterd.service

# cat /usr/lib/systemd/system/glusterd.service
[Unit]
Description=GlusterFS, a clustered file-system server
Requires=rpcbind.service
After=network.target rpcbind.service
Before=network-online.target

I will investigate why network.service fails and maybe try to add
NetworkManager.service to "After" list.

Thanks
Jarek
