Gluster 3.4 QEMU and Permission Denied Errors

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello Andrew,

How are you booting/managing VM's? Which user you use to launch them?

Have you enabled Gluster mounting from insecure ports? It needs two 
changes. You have to edit glusterd.vol (in /etc/glusterfs directory) and 
add line "option rpc-auth-allow-insecure on". Also you have to set 
volume option server.allow-insecure on (ie. gluster volume set volname 
server.allow-insecure on). Restart of glusterd and stop and start of the 
volume is required for these changes to take effect.
