Re: Is Garden limiting disk IOs ?


Guillaume Berche
 

Thanks Will.

Would other existing limits (e.g. nice, or fair cpu share) prevent one app
from using up all of the host disk io, or could such app impact its
neighbor containers (and other DEA/Cell process), and possibly up to denial
of service (e.g. a compromised app that was to impact the cf platform that
host them) ?

Guillaume.

Hi Guillaume,

No, Garden-Linux does not currently do any disk IO limiting.

Thanks,
Will

Out of curiosity, I'd like to understand whether Garden is limiting disk
IOs, similar to [2].

I do see disk space, inodes..., and network IOs limits described into [1]
but did not find block IOs.

Thanks in advance,

Guillaume.
