    Oracle VM Server 3.1.1 issues with NFS share

    470515
      Hi guys

      I am kind of stuck with the same issue for more than a week now. I have two virtual machines on Virtual box 4.1.8 (VM Server and VM Manager 3.1.1) and NFS following is disk/mount information on VM Server

      [root@oravms ~]# df -h
      Filesystem            Size  Used Avail Use% Mounted on
      /dev/sda3             3.0G  636M  2.2G  23% /
      /dev/sda1              99M   28M   67M  29% /boot
      tmpfs                 242M   16K  242M   1% /dev/shm
      /dev/sdb1             296G   17G  264G   6% /storage1
      /dev/sdc1             197G  320M  187G   1% /storage2
      none                  242M   40K  242M   1% /var/lib/xenstored
      192.168.0.20:/storage2
                            197G  320M  187G   1% /nfsmnt/cc745331-3df1-48d7-823c-b28faf2d87b3
      /dev/mapper/ovspoolfs
                             10G  263M  9.8G   3% /poolfsmnt/0004fb00000500005e689e9b4de9382f

      From last whole week I am trying to import a single VM template as a test object, Oracle E-Business suite 12.1.3 APPS tier and everytime once after a certain portion of the template unpacked, the VM server goes for a toast!! it either reboots or the NFS gets into a lock

      Both the virtual machines have 4GB memory, independant NICs dedicated for each virtual machine (as somebody else from forums suggested for it...)

      Please help me!!!

          Where is your NFS storage? Is it local?

          If its local. Why are you using NFS?

            Yes, I am exporting the local disks using NFS, and create a storage on NFS share, I don't know how else I could create a storage. I tried to read about local shares etc, no proper guidelines found
            If its local. Why are you using NFS?
            I don't know other methods to create storage and repositories. The only one plug-in storage section shows is "Oracle generic Network File System".

              hi user12273962

              I hope the following few details will assist you to provide me a suggestion to overcome this issue

              My Oracle VM server IP address: 192.168.0.20
              VM Manager IP: 192.168.0.23

              Both machines are tied to different NICs for avoiding excess traffic

              df -h on VM server
              [root@oravms ~]# df -h
              Filesystem            Size  Used Avail Use% Mounted on

              /storage1       192.168.0.20(rw,sync,no_root_squash,nohide)
              /storage2       192.168.0.20(rw,sync,no_root_squash,nohide)
              Should I export the mount points to another server? Please let me know.

              NFS was the only one file type recognized by the discovery process...I am quite new to virtualization, actually spent last whole week trying and fixing one or other issue with the VM server :D

              If you know how I could avoid NFS in the entire scenario (as this is just for learning purpose) I would be grateful :)

                Ok guys

                Looks like the problem is resolved. I shifted the NFS share from Oracle VM server to another server (this time VM Manager server) and the unpacking is happening without any troubles

                lesson learned, never ever TROUBLE VM server with anything else :)
