We have 2 server machines (Server1, Server2), they backup each other using keepalived. We have NFS servers (nfs-kernel-server) running on each of servers. We have a client PC which mounts NFS share like this: Code: 192.168.16.166:/var/acsd on /misc/acsd type nfs4 (rw,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=1200,retrans=2,sec=sys,clientaddr=192.168.26.67,local_lock=none,addr=192.168.16.166) 192.168.16.166 - is a keepalived interface for both servers. When we shut down Server1 - NFS mounting breaks like this: Code: ls: cannot open directory .: Stale NFS file handle If we remount just after this - everything works ok, I can see files from Server2. Something breaks when keepalived switches servers. Is there a way to fix that?
