My distributed volume had an issue on Friday which required a reboot of the primary node. After this, I'm having a strange issue: When I have the volume mounted via ganesha-nfs, using either the primary node itself or a random workstation on the network, I'm seeing files from both volumes, but I'm not seeing any directories at all. It's just a listing of the files. But I *can* list the contents of a directory if I know it exists. Similarly, that will show the files (in both nodes) of that directory, but it will show no subdirectories. Example: $ ls -F /mnt flintstone/ $ ls -F /mnt/flintstone test test1 test2 test3 $ ls -F /mnt/flintstone/wilma file1 file2 file3 I've tried restarting glusterd on both nodes and rebooting the other node as well. Mount options in fstab are defaults,_netdev,nofail. I tried temporarily disabling the firewall in case that was a contributing factor. This has been working pretty well for over two years, and it's survived system updates and reboots on the nodes, and there hasn't been a recent software update that would have triggered this. The data itself appears to be fine. 'gluster peer status' on each node shows that the other is connected. What's a good way to further troubleshoot this or to tell gluster to figure itself out? Would "gluster volume reset" bring the configuration to its original state without damaging the data in the bricks? Is there something I should look out for in the logs that might give a clue?
