NFS multiple write error.

Hi,

We are taking the mksysb backup to NIM server's NFS mount point (/backup). We have mounted /backup to all the clients /backup and full permission. When multiple mksysb backup starting simultaneously to the NIM server's shared NFS mount point then only one backup is running and all others are failing. One by one the backups are completing successfully. We are using soft option for mounting the NFS file systems. How we can write multiple backups simultaneously to the NFS shared mount point

  1. Command you use to mount NFS share
  2. grep your-share /etc/exports from NIM server
  3. Command you use to make a mksysb backup

What agent.kgb is hinting at is: you shouldn't export filesystems belonging to NIM by hand - never ever! Use the NIMs methods and it will automatically generate the necessary NFS shares, mount them, unmount them and deconfigure them afterwards. A typical problem with failing NIM methods is that supersets of the NIMs working directories are exported by hand.

To do a mksysb backup correctly means executing something similar to the following command from the NIM server:

 root@nim # nim -o define -t mksysb \
                          -a server=<nim master> \
                          -a location=/nim/path/to/image \
                          -a mk_image=yes \
                          -a source=<client>  image.name

I hope this helps.
