Reqmaster fails even if reqmaster is allowed at remote replica

 Technote (troubleshooting)
 
Problem(Abstract)
This technote explains how to resolve an error, You do not have permission to request mastership from the sibling replica, that can occur when requesting IBM Rational ClearCase MultiSite mastership even if reqmaster is allowed at the remote site.
 
Symptom

Running a reqmaster command fails with an error:


$ cleartool reqmaster -nc my_element@@/main

cleartool: Error:  my_element@@/main

The following blocked the "reqmaster" operation at replica "remote_replica".

    You do not have permission to request mastership from the sibling replica.

 
Cause

If the VOB is stored remotely on a network attached storage (NAS) device, the root user on the VOB server may not have write permission to the NAS device where the VOB storage is located.
 
Diagnosing the problem

At the remote site (where the mastership is requested):

$  cleartool describe my_element@@/main

branch "my_element@@/main"

  created 20-Dec-04.17:35:11 by me.Domain Users@my_pc

  branch type: main

  master replica: remote_replica@/vob/my_vob

  request for mastership: allowed

  Element Protection:

    User : vobadm   : r-x

    Group: mygroup   : r-x

    Other:          : r-x

  element type: text_file


At remote site, mastership ACL cannot be retrieved:

$ multitool reqmaster -acl -get vob:/vob/my_vob

msadm_vob_rfm_get_acl_V1: RPC: Unable to receive; errno = Connection reset by peer

multitool: Error:  vob:/vob/my_vob

The following prevented the local "get ACL" operation.

Could not get Request Mastership ACL.

 
Resolving the problem

Refer to the Enabling requests for mastership section in the IBM Rational ClearCase information center for information about enabling mastership requests for replicas in a VOB family.

Make sure that the root user on the VOB server has write permission to the NAS device where the VOB storage is located.
