[Gluster-users] mount with one alive node in replica set

It waits for the other node's glusterd also to be up so that they are in sync. You can override this behavior by doing a `gluster volume start <volname> force` to bring up the gluster process only on this node and then mount the volume. -Ravi

[Gluster-users] mount with one alive node in replica set
Thank you for you answer! I check recomendation: 1. On first node closed all connection from second node by iptables. Check that on both nodes "gluster peer status" return "Disconnected". Check that on both nodes share was mounted and work well like local file system. 2. Rebooted second node (remind first node closed by iptables). Second node booted without problem and proccesses of glusterfs started: # ps aux | grep [g]luster root 4145 0.0 0.0 375692 16076 ? Ssl 13:35 0:00 /usr/sbin/glusterd -p /var/run/glusterd.pid "gluster peer status" return "Disconnected" and volume started on localhost: # gluster volume info Volume Name: files Type: Replicate Volume ID: 41067184-d57a-4132-a997-dbd47c974b40 Status: Started Number of Bricks: 1 x 2 = 2 Transport-type: tcp Bricks: Brick1: xxx1:/storage/gluster_brick_repofiles Brick2: xxx2:/storage/gluster_brick_repofiles ?ut I cann't mount this volume: # cat /etc/fstab |grep gluster 127.0.0.1:/files /repo glusterfs rw,_netdev 0 0 # mount /repo Mount failed. Please check the log file for more details. Part of log I have sent in first message. If I will open first node by iptables I could mount without problem, but what must I do, when I lost one node and I have probability reboot another node? 2015-06-17 18:46 GMT+03:00 Ravishankar N <ravishankar at redhat.com>:> > > On 06/17/2015 07:04 PM, ????? ??????? wrote: > >> If we turn off one server, another will be work and mounted volume will >> be use without problem. >> But if we rebooted our another server, when first was turned off (or >> gluster was stopped on this server), our volume cann't mount (glusterd >> started). >> > If both nodes are down and you bring up only one node, glusterd will not > start the volume (i.e. the brick, nfs and glustershd processes) > automatically.
