Hi Dharmesh, we had seen a similar problem in our testing and reminoring the volumes that needs to be exported using "vxdg reminor" command to less than 255 solved the problem.
HTH thanks, Raghu -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dharmesh Kamdar Sent: Monday, October 16, 2006 7:44 AM To: Tom Stephens Cc: veritas-ha@mailman.eng.auburn.edu Subject: Re: [Veritas-ha] Unable to mount volumes on nfs-client in VSF 4.1MP2for RHEL 4 AS U3 hosts..... Hi Tom, Thx for the quick feedback.... We've already tried this suggestion (from Symantec tech support). This is what we did: 1) hastop -all 2) One one VCS host, assigned 2 BRAND NEW LUNS (non-shared) from our storage and created a new TEST_DISKGRP with those 2 LUNS. 3) Created one test volume and vxfs on it and mounted it on /mnt/testvol (perms were 777). (for e.g. mout -t vxfs /dev/vx/dsk/TEST_DISKGRP/testvol /mnt/testvol) 4) In the /etc/exports file, we put the foll.line: /mnt/testvol *(rw,sync) 5) exportfs -ra 6) From the NFS client, tested it via: $>mount -t nfs 192.168.2.185:/mnt/testvol /mnt/test_vol 7) The result was the same: "reason given by server: Permission denied." We've already checked the comms..The nfs-client can ping the vcs-servers and the virtual-IP addr (for NFS). Similarly the VCS-hosts can ping successfully the NFS-client... We got one more additional server with the same architecture and plain RHEL AS 4 U3 (NO VERITAS component)...we tried exporting a local FS and mounting it on our NFS-client successfully. While going thru' various NFS-mailing list, I came across one more possible soln is to add the following lines to /etc/fstab on VCS-hosts: nfsd /proc/fs/nfsd nfsd auto,defaults 0 0 sunrpc /var/lib/nfs/rpc_pipefs rpc_pipefs auto,defaults 0 0 (https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=126263) I've already added 1st line with no avail..But tomorrow I will try to add 2nd line and see if that helps.
