Thanks to all those that replied.
Had various replies ranging from:
- use quotacheck to "fix" the discrepancy
- open files are not cleaned up by verify
- use the vdf or vdu command
What I found:
- quotacheck does not work on clusters. I get the error "quotas are not
supported in a cluster environment"
- The verify I ran was an offline verify so there were no open files and the
verify did not resolve the problem.
- The "vdf domain#fileset" command reports exactly the same usage
information as df, which is wrong.
- The "vdf domain" reports correct domain usage, but is not fileset
specific.
- There is no vdu command.
So I still do not have a solution. Any other ideas?
Thanks,
Mark.
