fsid

fsid=0

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?
