UIM - UMP - Linux - NFS Troubleshooting Tips

Blog Post created by Alessandro_Kuramoto Employee on Sep 22, 2017

Here is a quick post about the errors bellow, if you has a misconfiguration on your /etc/exports file when you configure Multiple UMP Servers:

 

On NFS server side:

 

if you ran:

exportfs -a

 

and got the error

exportfs: No options for /opt/ca/nimsoft/probes/service/data/document_library 10.y.z.10: suggest 10.y.z.10(sync) to avoid warning
exportfs: No host name given with /opt/ca/nimsoft/probes/service/data/document_library (rw,no_root_squash), suggest *(rw,no_root_squash) to avoid warning

 

 

And on NFS client side:

 

if you ran:

mount -t nfs <primary>:/<UIM_installation>/probes/service/data/document_library <UIM_installation>/probes/service/data/document_library

 

or

mount -a

 In case of you use /etc/fstab to mount the NFS automatically when OS start.

 

and got the error:

mount.nfs: access denied by server while mounting 10.y.z.10:/opt/ca/nimsoft/probes/service/data/document_library

 

 

Look to your /etc/exports and be sure if your configuration is ok:

File: /etc/exports - This configuration is ok
/opt/ca/nimsoft/probes/service/data/document_library 10.y.z.10(rw,no_root_squash)

 

The errors above was caused, because in my file had a space between 10.y.z.10 and (rw,no_root_squash), like this: 10.y.z.10 (rw,no_root_squash), so correct it.
