[Gluster-users] Node failure timeouts and mount issues on boot
Hi folks, I have a test gluster vol setup between 2 physical servers. Centos 6 / Gluster ver 3.4.2-1.el6 Volume Name: storevol0 Type: Replicate Status: Started Number of Bricks: 1 x 2 = 2 Transport-type: tcp Bricks: Brick1: store01.gluster:/mnt/brick0 Brick2: store02.gluster:/mnt/brick0 Each node (store01 and store02) also mounts the gluster vol locally in fstab: store01.gluster:/storevol0 /home glusterfs defaults,_netdev 0 0 and store02.gluster:/storevol0 /home glusterfs defaults,_netdev 0 0 When one node reboots I notice 2 results: - The /home mount on the remaining node is unavailable for 30-60 secs before becoming available. - The rebooted server does not mount /home on boot, but a mount request after boot up works fine. I know I can tune the timeout setting and in my particular use case it wont matter so much, however how would this work if VMs where stored on this volume, surely the storage going missing for any number of seconds would cause a real problem with running virtual machines? How can I get the mount to work on reboot, _netdev seems not to be helping?
