##:~# quotacheck -avugm quotacheck: WARNING - Quotafile //quota.user was probably truncated. Can't save quota settings... quotacheck: WARNING - Quotafile //quota.group was probably truncated. Can't save quota settings... What does the above mean and what is it doing. Did a google search with with full warning and it's still a bit of a mystery?
Have you run this as root user? Did you get the same error when you run the command again? I think its a warning when the quota files are build the first time.
Nothing to worry about. This happens when the quota files are generated for the first time. As long as quotaon does not give an error everything is fine.
