I used quota in Ubuntu10.10 to configure/etc/fstab to restart
Quotacheck-avug
Quotacheck: you cannot guess the format of the file name on/dev/sda3. Specify an exact format in the command line.
Then run the quotacheck-uvgm command to indicate that the command parameter is incorrect.
The following error message is displayed when quotacheck-uvg/home is used:
Quotacheck: Mountpoint (or device)/home not found or has no quota enabled.
Quotacheck: Cannot find filesystem to check or filesystem not mounted with quota option.
The quota command cannot be used either.
How can I use quota correctly? Thank you!
