Hi! I get an error when I execute the command Code: mount -o remount / when installing quota. I've always had problems with mount on my hard drive. It is a Western Digital 200GB Serial ATA drive. Which reminds me that whenever my kernel boots, it says Code: ata2: disabling port . Right now my xfs file system is read only, but I can access it from KNOPPIX live cd.
What's the exact error message? If the mount command doesn't work, try to reboot your machine (instead of running the mount command). That should work then. I'm not quite sure if quota works flawlessly on XFS...
Ok, then run Code: shutdown -r now instead of Code: mount -o remount / Afterwards, you can go on with your quota configuration.
