This is the fstab entry: 1.1.1.1:/nfsshare/all /shared nfs4 defaults,tcp,intr,relatime,async,acl= 0 9 The NFS server crashed and was offline, that made all clients block. Ev= en=20 after the NFS server was up again, most clients were stuck to the point= they=20 had to be rebooted. What mount options should we use so clients don't b= lock=20 completely when the NFS server is gone? It's no problem to unmount the = NFS=20 share, or get errors, but the clients must not stop their work. --=20 mit freundlichen Gr=C3=BCssen, Michael Monnerie, Ing.
