NFS clients fails to mount the nfs share exported using wildcard character in /etc/cluster.conf

Solution Verified - Updated -

Issue

  • When the NFS share is exported using a wildcard, NFS server refuses the connection from clients. Below is the entry for nfsclient resource in /etc/cluster.conf file:
<nfsclient allow_recover="1" name="res_NFSclient" options="rw" target="Host*-nfs.net"/>
  • With above entry in cluster.conf, NFS clients fails to mount the share and following error is observed in logs:
Aug 26 01:11:28 nfsserver1 mountd[6102]: refused mount request from 192.168.0.20 for /mnt/share (/mnt/share): unmatched host
  • When above entry is modified as shown below, it works without any issues:
<nfsclient allow_recover="1" name="res_NFSclient" options="rw" target="Host1-nfs.net"/>
