I have a strange situation here at the customer site that I have never seen before and I am hoping someone can point me in the right direction.
I have a server that is able to mount a volume via NFSv3 from a vserver. When I try to mount another volume from the same vserver via NFSv3 I get this message:
[root@fgtd-333333-aspadavecchia-db001 mnt]# mount -t nfs -v -o rw,nointr,noacl,noatime,rsize=32768,wsize=32768,defaults,vers=3,tcp,mountproto=udp,bg,hard,nolock vsnfsbbl.bbcs1.trcl1va2.mhint:/bbl_nfs_td1_333333_aspadavecchia_dbo/db001 /home/oracle

mount.nfs: mounting vsnfsbbl.bbcs1.trcl1va2.mhint:/bbl_nfs_td1_333333_aspadavecchia_dbo/db001 failed, reason given by server: No such file or directory
If I mount using no options, the mount is successful but only with NFSv4
[root@fgtd-333333-aspadavecchia-db001 mnt]# mount -v vsnfsbbl.bbcs1.trcl1va2.mhint:/bbl_nfs_td1_333333_aspadavecchia_dbo/db001 /home/oracle
mount: no type was given - I'll assume nfs because of the colon
mount.nfs: timeout set for Wed Jul 27 21:04:10 2016

Here is the volume that we can mount via NFSv3:
[root@fgtd-333333-aspadavecchia-db001 mnt]# mount -t nfs -v -o vers=3 vsnfsbbl.bbcs1.trcl1va2.mhint:/asp/asp /mnt/asp
mount.nfs: timeout set for Wed Jul 27 21:09:59 2016
mount.nfs: trying text-based options 'vers=3,addr=10.8.236.7'
mount.nfs: prog 100003, trying vers=3, prot=6
mount.nfs: trying 10.8.236.7 prog 100003 vers 3 prot TCP port 2049
mount.nfs: prog 100005, trying vers=3, prot=17
mount.nfs: trying 10.8.236.7 prog 100005 vers 3 prot UDP port 635
vsnfsbbl.bbcs1.trcl1va2.mhint:/asp/asp on /mnt/asp type nfs (rw,vers=3)
I even tried using the same export policy that the /asp volume uses.
