arcserve-KB : "Write permission needed to continue" while adding NFS as Backup Storage.

Last Update: 2016-04-25 14:38:22 UTC

Error Message:

The following is the error message displayed while adding NFS as Backup Storage to CA ARCserve D2D for Linux Server.

'Write permission needed to continue'

Description:

The above screen explains adding 'NFS' as Backup Storage for D2D backups. You can also find the following errors in the webservice.log and webui.log files under /opt/CA/d2dserver/logs directory.

[ERROR] LinuximagingServiceImpl.convertServiceException2AxisFault - 12884901895

[ERROR] LinuximagingServiceImpl.convertServiceException2AxisFault - Write permission is needed to continue.

Solution:

While configuring NFS server, you must ensure the export options must be read/write and no root squashing for exported directory.

For example: 

Login as a root user, Open the NFS configuration file

#  vi  /etc/exports

/nfs   0.0.0.0/0(rw,no_root_squash)

In the above example, there is a directory in / partition named “nfs” is being shared with client IP “0.0.0.0/0” i.e., any address with read and write (rw) privilege, you can also use specific network or hostname of the client in the place of IP in above example.

rw: This option allows the client server to both read and write access within the shared directory.

no_root_squash  -- This phrase allows root to connect to the designated directory.

More Information:

Root squashing is enabled by default and you need to disable it explicitly.
