Objective
We want to know network load balancer backup pool will work with NFS or not. And how many latency when main pool switch to backup pool…
PS: This is just a lab… Using GCS bucket notification service to sync running servers’ file will better than others… Or using GCS as file read write service will excellent!
Network Load Balancer(nfs-lb / 130.211.245.39)
nfs-1(nfs-pool)
nfs-client(104.155.196.85)
nfs-2(nfs-pool-bk)
rsync
Prepare servers - nfs-1, nfs-2
● nfs server○ yum update -y && yum install rpcbind nfs-utils -y○ /etc/init.d/rpcbind start○ /etc/init.d/nfs start○ /etc/init.d/nfslock start○ chkconfig rpcbind on○ chkconfig nfs on○ chkconfig nfslock on
Prepare client - nfs-client
● nfs-client○ rpcinfo -p [remote address]○ mount -t nfs [load balancer ip]:/data /mnt
See the test - http://youtu.be/WsEyXOmI4OY
Issues
● rapidly switch nfs server will let nfs client crash● ever switch between main pool to back pool will
cost about 30sec ~ 60sec
