Clearcase - Unable to access VOB - ls: reading directory - Permission denied

问题

Clearcase Server Version - 8.0.1.19
OS – Centos - 7.6.1810 (Core)

Problem: Created new VOB, Mounted the VOB then created dynamic view on server successfully. From VOB root directory ls command shows below error.

ls: reading directory .: Permission denied
total 0

I have executed below protect commands.

cleartool protectvob -f -chown ccadmin -chgrp testvob-grp /vobstg/testvob.vbs
cleartool protect -chown ccadmin -chgrp testvob-grp -chmod 775 -r .


[root@VOB-Server /]# cleartool desc -l vob:/vobstg/testvob

View owner has rwx (all) permission. So in newer version of Clearcase do I need to enable configuration for even root id and VOB-owner ID?

I am using default config spec

element * CHECKEDOUT
element * /main/LATEST

Dynamic view created with root account. While describing the VOB tag it shows below error.

[root@VOB-Server]# cleartool desc -l /vobstg/testvob
cleartool: Error: No permission to resolve: "/vobstg/testvob".
cleartool: Error: Unable to access "/vobstg/testvob" because either it is unreadable or its containing VOB is not accessible to the current user.

Whereas with VOB Owner’s account/ID (ccadmin), I can able to describe the VOB.

回答1:

First, it depends on your config spec (I will assume element * /main/LATEST)

Second, your question mentions root@VOB-Server: make sure to do the ls test as the view owner: ccadmin.testvob-grp

Still as the view owner, do a id -a to check if the primary group (or one of the secondary groups) is part of the VOB group (VOB, not view, which is correctly protected)

See "Access control for VOBs" and "About Additional Groups in the VOB's group list"

You can use the cleartool describe command to display the owner, group, and supplemental group list for a VOB.

cleartool descr -l vob:/vobs/vobtag

Whereas with VOB Owner’s account/ID (ccadmin), I can able to describe the VOB.

That is expected: only user with the primary Vob group as part of their group would be able to access the Vob. root has not testvob-grp in its groups (id -a)
