History of Per Context Quota

== (for 2.4.22 as Test for 2.6.x) ==

you will need ...

* linux-2.4.22

* [patch-2.4.22-c17e.diff.bz2]

* [patch-2.4.22-c17e-mq0.11.diff.bz2]

* [patch-2.4.22-c17e-mq0.10-cx0.06.diff.bz2]

* [patch-2.4.22-c17e-mq0.11-cx0.06-cq0.11.diff.bz2]

* [patch-2.4.22-ctx17a-vr0.13.diff.bz2]

* [vr-tools-0.14.tar.bz2]

* [cq-tools-0.06.tar.bz2]

what should be tested?

* this will give you a separate quota space per vserver, which,

: after activation, independently tracks the quota for a specific

: context ...

how to start?

* get the tools, and the patches

* patch your kernel ...

:tar xvjf linux-2.4.22.tar.bz2

:mv linux-2.4.22 linux-2.4.22-test

:cd linux-2.4.22-test

:bzcat ../patch-2.4.22-c17e.diff.bz2 | patch -p1

:bzcat ../patch-2.4.22-c17e-mq0.11.diff.bz2 | patch -p1

:bzcat ../patch-2.4.22-c17e-mq0.10-cx0.06.diff.bz2 | patch -p1

:bzcat ../patch-2.4.22-c17e-mq0.11-cx0.06-cq0.11.diff.bz2 | patch -p1

:bzcat ../patch-2.4.22-ctx17a-vr0.13.diff.bz2 | patch -p1

** select the VROOT device and quota (old & new)

** select the Persistent Context ID method of your choice

** compile and install kernel and tools (vr/cq)

: after reboot ...

* mount the vserver filesystem with the 'tagctx' option

: (do not use remount, as it won't work)

: mount -o tagctx,usrquota,grpquota /dev/shared/device /vservers

* setup one vroot device for all vservers on a shared partition

: (as described in the INSTALL and on my pages) and use the folowing

: commands to activate quota for context N = 100

** create a vroot device

:: mknod /dev/vroot/device b 4 device

** copy the vroot device to the virtual server, or create an

:: apropriate block device node there ...

:: cp -va /dev/vroot/device /vservers/<name>/dev/hdv1

** add a context quota hash for the new context

:: cqhadd -v -x 100 /dev/vroot/device

:: (result will be success, if everything is okay)

** make sure that your vserver mtab entry looks like this

:: /dev/hdv1 / ufs rw,usrquota,grpquota 0 0

** change to vserver TEST (context = 100) and do quotacheck -vaug

:: (the quota files should be created)

** enable quota with quotaon -vaug ...

thats it ...

questions?

* please contact me, if you have any ...

you can use [patch-e2fsprogs-1.34-cti0.01.diff.bz2] to patch the tools

to show and change the context information for files ...
