Periodic maintenance
Periodic attention to storage management and repository integrity is an important administrative function. These topics describe VOB and view storage management tasks, the checkvob utility, and the DevOps Code ClearCase® scheduler, which you can use to automate many periodic maintenance chores.
About checkvob
VOBs have complex internal and external relationships that can sometimes be disrupted by system or network failures or when a VOB is restored from backup. checkvob is a cleartool subcommand that can find, and in many cases fix, a variety of problems in these relationships.
Using checkvob to find and fix internal VOB inconsistencies
A VOB storage directory contains a VOB database and a number of storage pools. Any operation that modifies VOB data makes changes to the database and at least one pool. When inconsistencies arise between the contents of a VOB database and the contents of its pools, VOB data integrity may be damaged.
Storage pool problems
Source, DO, or cleartext pool: Bad pool roots

Source, DO, or cleartext pool: Bad pool roots

Description: Misnamed or misidentified pools.
Cause: mkpool, rmpool, or rename pool in the interval between database and storage pool reference times.
Fix processing: Create the pool_id file if it is missing from an existing pool whose name and location are recorded in the VOB database. The checkvob command cannot fix any other problems related to pool names or location. It skips to the next pool kind as soon as it finds a pool of the current kind that has any problem other than a missing pool_id file.
