I'm no expert at setting up disk quotas, but from what I've read, you seem to be mixing journalled and unjournalled mount options. Also, I don't know if using quotas on the root (/) partition is a good idea, the info I've found seems to be focusing on /home partitions, but like I said, I'm no expert here, so I'll assume you know what you're doing.

Just to make sure you can tell the difference, the unjounalled entry uses "usrquota", and the journalled entry uses "usrjquota" and an argument as well as the extra part "jqfmt=vfsv0". You were mixing the two, which may have caused the problem.
