I have never had to use quotas before so this is a totally new concept for me
to get my brain around.

before i continue, i assume that quotas will work on reiserfs ? every system
we have is reiser.

There are several documents about them for vservers but this one looks like it
may be the most current?


so... with the below quote from the page, i could arbitrarily choose a
vserverx block device?

Use vrsetup to tell the kernel what block device you want to handle quota for:

vrsetup /dev/vroot/0 /dev/evms/vs


vrsetup /dev/vroot/0 /dev/lvm/vserver0

so in my case since we use udev. i could issue
vrsetup /dev/vroot1 /dev/sda4 ?

what would i replace lvm or evm with? i am using neither.. i simply created
one huge volume on sda4 which all the guests use.

setting up a default mtab in /etc/vservers/guest/apps/init/mtab looks pretty
straight forward, and copying hdv1 looks easy enough..

so there are a few questions out of all this... arbitrarily choose a vserverx
block device? what to use in place of evm or lvm above? then the instruction

- inside the guest run:
quotacheck -maugv

umm.. there is no quotacheck program or script inside the guest that i can
find... what package is it included in?

basically all i want to do is assign each guest a limited portion of disk
space. not user sensitive, just guest sensitive. right now each of them sees
625gb free.. which is ok for the guest network servers i manage, but when we
move customer colo servers to this, when users see this much space they will
go crazy with it.

an alternative would be to create a fixed size (maybe 20g or 40g) file mounted
via loopback creating a virtual disk for each of the colos as their
'drive'..maybe that would be better? then they could never corrupt anything
to do with our main disks...
