From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0) Description of problem: i'm setting an NFS service using the NFS druid. I have 2 nodes (A and B) and NFS configuration is Active/Passive. i have configured 2 NFS Export Clients with rw permission (A and B). if NFS server is running on A, then i cannot mount NFS client on A while i can mount it on B; if NFS server is running on B, then i cannot mount NFS client on B but only on A. I have added in /etc/fstab on both nodes: 10.6.34.109:/san /mnt/san nfs rw,rsize=8192,wsize=8192 0 0 if i have NFS server running on A and start nfs client on A, i get: [root@A]# service netfs start mount: 10.6.34.109:/san failed, reason given by server: Permission denied if i start nfs client on B i get success. now if i change permission in NFS Export Clients (using NFS druid) and allowed rw at world magically i can mount NFS client on A too.
