In nfs4 this is makes this export the root relative to which all others "base point under which all directories the server is exporting to a certain client are located"
nfs4.2
HOWTO
On server
show mounted exports in /proc
Not all are currently active, exportfs seems to update this
cat /proc/fs/nfs/exports
show clients
Not all are currently active
cat /var/lib/nfs/rmtab
list connected clients
IP=`ip route get 1 | awk '{print $NF;exit}'`
netstat -an | grep $IP | grep 2049 | awk '{ print $5 }'| sed 's/:.*//g'
FAQ
Client
mount.nfs: portmap query failed: RPC: Remote system error - No route to host
Could be firewall,
firewall-cmd --permanent --add-service=nfs firewall-cmd --permanent --add-service=mountd firewall-cmd --permanent --add-service=rpc-bind firewall-cmd --reload
mount.nfs: requested NFS version or transport protocol is not supported
portmap query retrying: RPC: Program not registered
mount to NFS server xxx failed: System Error: Connection refused.
SUNRPC: reached max allowed number (1) did not add transport to server
You might be using 2 interfaces connecting to same server
mount -t nfs taking very long
mount.nfs: No route to host
firewall, really
Failed: stale file handle
umount -fl
versions supported by server
cat /proc/fs/nfsd/versions
nfs: server 1.2.3.4 not responding, timed out
??
mount.nfs: access denied by server while mounting
Could be wrong path in exports, maybe nfs3 vs nfs4.2 confusion?
