Hi Sirk,
If you want some practical information on ploop: We are using it in a
highly productive environment.
It was either, try ploop and hope it works, or have the systems fail
every 2nd day.
So we decided to use ploop and are more than happy.
It even solves a lot of issues we had with the private areas directly
on the nfs share.
But of course, thats totally up to you.
I started with only a few "unimportant" CTs and then merged everything
after a while (42 CTs).
Thanks for the info, much appreciated!
Maybe a little off topic, but I am curious to know: At the moment I
find it very convenient to go directly into a containers filesystem
from the hardware node - i.e. something like
/vz/private/xxx/var/log/... etc - Would I be correct in presuming
that by using ploop this will no longer be possible? I know I could
just setup a test system and try it out but if you know already it
would save me some time ;)
It's not very practical to access the containers from the VZ/private
mount point, as it breaks for example the quota stats of the container.
If you still want to do things there better go for the VZ/root mount
point. (Advice given to me by one of the now-a-days developer of
Viruozzo) And as you already mentioned ploop, as far as I know the
ploop-container will be mounted to VZ/root of the CT and you'll still
have access to the info in there.
So you have a different FileSystem for the "problem"-Container that is
even on a different disk ?
If that is the case, this CT should not affect the others at all
in terms of IO.
Indeed, this is the only container on that filesystem and that
physical drive. This time there were no "spill over" but previous
times when load hit 50 or more the load certainly did spill into
other containers.
Best,
Rene
