I was trying to setup quota for my ftp users on fresh Ubuntu 16.04. I was using this flow
But at the end came to flowing error, after running "quotaon /" i got error
quotaon: using //aquota.user on /dev/vda1 [/]: No such process
quotaon: Quota format not supported in kernel.
I found alternative tutorial here which uses
apt-get -y install linux-image-generic apt-get -y install linux-headers-generic apt-get -y install linux-image-extra-`uname -r`
kernel overwriting method which i think is not so good approach.
I wondered if there is not present some alternative to "quotaon" ? as it is removed from kernel then there should be some normal alternative functionality to it ? or some other way to enable quotaon without re installation of "linux-image-generic ..." ?
