I have successfully added disk quotas to my FC6 system, so that the user "backup" cannot create files more than 1 block on / The reason I implemented this was because I backup my system to a USB drive mounted to /media/drivebay/backup1. However, if the drive is not mounted, then my root drive fills up (writing to the /media/drivebay/backup1 folder) and linux hangs. The problem is, that the user quota applied to / is also applying to my /media/drivebay/backup1 device too -only when accessed remotely as a SAMBA share! (I don't think that it should; although /media/drivebay is on the same partition as / the backup1 subdir is my mountpoint). In other words, the user "backup" cannot write more than 1 block to /media/drivebay/backup1 when accessing via SAMBA. Why is this - and how do I fix it? My goal is to prevent the user backup from writing more than 1 block to / , but as much as he wants to /media/drivebay/backup - when copying data from remote machines. What do I have to change? (I know that I could do something similar in a script, but I want to learn about quotas). the usrquota program does not exist in my distro (FC6), but "repquota /media/drivebay/backup1" shows: repquota: Mountpoint (or device) /media/drivebay/backup1 not found. repquota: Not all specified mountpoints are using quota. This suggests that quotas are not applied to that mount point. However....I can r/w just fine as user "backup" with quotas off, and not with quotas on. Thanks\M
