Today, let me share this problem that we could see on working on Rhel 6.x and CC.
Inside a dynamic view, and vob directory, we are unable to read elements unless we check out them first.
Where the ClearCase Client machine runs Red Hat 6.x and reaches the View and Vob Stores through NFS.
By default Red Hat 6.x uses nfs version 4, so if the VobServer or NAS device supports NFS version 4, the client machine will mount using nfs 4 that will present the wrong behaviour.
3.2) Alternate to Vob directory.
3.3) Try to read some files.
4) How to solve this problem?
This is fixed in ClearCase 7.1.2.10 and 8.0.0.6.
Remount the VobStore using nfs version 3 instead 4.
For while we have some issues when using NFS version 4, so keep using version 3 instead.
